Dual-Path Alarm Communicators Posts

Johnson Controls released a Technical Advisory Bulletin on Monday noting that some PowerSeries Neo, Pro LTE, and Internet Dual-Path Communicators have labeling errors. The serial number on the box appears to be incorrect. Comms built between August 15, 2021, and July 29, 2022, are affected.

The model numbers affected are the DSC TL880LECVZ, TL880LECAT, TL880LEBAT, TL880LEBTL, and TL880LECTL. This is a labeling error only and does not affect the signal transmitting, or Alarm.com remote control capabilities of these communicators in any way. The mixup seems to be with the name on the label on the product, and the serial number on the label on the box.

The model name listed on the label of the product is incorrect, while the serial number listed on this label is accurate. The model name listed on the sticker for the box is correct, but the serial number listed on the box is incorrect. So, be sure when registering one of these units that you use the serial number from the sticker for the product and not the one from the box.

The following products, built during the listed date range, are affected:

Beginning July 29, 2022, new, updated and correct labels should be placed on these products. Remember, the performance of communicators that were manufactured during this timeframe is not compromised. This is only a labeling error, so as long as the serial number taken from the sticker affixed to the product itself, or the IMEI number from the printed circuit board is used everything should work as intended. DSC offers a handy Date Code Lookup tool at this site. You can find information on looking up a date code for any DSC product on that page.

The fact that this issue wasn't discovered sooner seems to indicate that this is a very minor issue. What do you think about this announcement? Do you often use these communicators? Have you run across this issue? Leave us a comment below and tell us what you think. We always enjoy hearing from our readers. That's all for today, until we meet again, stay safe!

On July 5, 2022 Resideo announced that all LTEM-PA, LTEM-PV, LTEM-PIA, and LTEM-PIV communicators will undergo a slightly revised activation process. Upon registration, if the communicator is not using the latest firmware version, it will automatically receive an Over-the-Air (OTA) update.

This announcement came in the form of MyWebTech Technical Notification #83. For those communicators with a WIFI or Ethernet connection, the OTA update will be performed using this communication path. If WIFI or Etehrnet is not available, then cellular data will be used. The update process typically takes about five (5) minutes, but when cellular is the only communication path available, it may take longer. The length of time a cellular upgrade takes also depends on the cellular signal strength.

During the update, the communicator's LED's will light according to where the communicator is in the two-stage process:

• Firmware Downloading: REG, Status, and Fault LEDs will fast-blink in unison.
• Upon Firmware Completion: The device will reset, then all five (5) LEDs, REG, Status, Fault, Cell, and WIFI/Ethernet will fast blink in sequence.

The OTA software update will cause the communicator to generate a few different messages to the central station. These messages indicate the beginning and end of the software update process. The messages sent are as follows:

• E903 - Application Code Update (Remote Download begins)
• R903 - Application Code Update Restore (Remote Download Completed)
• E904 - Application Code Update Failure (Remote Download/Update Failed)

For Alarm Grid customers, this notice means that if you are using one of the LTEM-P Series communicators listed above, it is more important than ever that you have your equipment installed and ready when your activation appointment time rolls around. In particular, anyone who will be using cellular communication only, as any OTA update required may take some time to complete, and we currently have no way of knowing how long.

If you have any questions about this notice, reach out to your alarm dealer for details. If you are an Alarm Grid customer, you can send us an email at support@alarmgrid.com. We're here Monday - Friday from 9:00 am - 8:00 pm Eastern time to answer your questions.

The Resideo LTEM-PA and LTEM-PV are dual-path capable communicators that use the LTE Cat-M1 network. During the global chip shortage, these radios have come to prominence because of their availability in the absence of other LTE communicators. They provide nearly the same speed as LTE comms.

Another feature that differentiates the LTEM-PA and LTEM-PV from other communicators is their modular design. These radios are considered a part of the ProSeries lineup, which includes the Honeywell Home PROA7 and PROA7PLUS and the Resideo PROA7C and PROA7PLUSC. The reason for this is that many of the add-on modules that can be used with the ProSeries panels can also be used with the LTEM-P communicators. Including the PROWIFI or PROWIFIZW, the PROLTE-A or PROLTE-V, and the PRODCM.

The LTEM-P Series communicators support an ethernet connection, but if you find yourself in a situation where a wired connection is not possible, then you can install the PROWIFI or PROWFIZW, which will give you WIFI, or WIFI and Z-Wave Plus capabilities. The ability to add a modular cellular unit is exciting as it allows you to install a separate LTE communicator to use instead of the built-in LTE Cat-M1 communicator. This will come in handy if you purchase an AT&T LTEM-PA, but find out later that Verizon would provide a better signal in this particular installation. Also, far in the future, when LTE is eventually phased out, whatever takes its place can easily be installed in the unit, rather than having to replace the entire communicator.

The PRODCM is a dialer-capture module. It allows the LTEM-P Series communicator to work with an alarm panel that has a built-in dialer and can report using Contact ID Format. The PRODCM installs inside a slot in the LTEM-P Series communicator, then two wires are connected between it and the Tip and Ring terminals on the alarm panel. The panel believe's it is dialing out over a phone line, but the module captures the signal, and transmits it via IP, or Cellular. Many of these add-on modules are also compatible with the ProSeries panels, which is why the LTEM-P Series are considered a part of the ProSeries lineup.

Tip 1: Power Wiring

The LTEM-PA and LTEM-PV come with a 9VDC power supply. Depending on the communicator you may be replacing there could be an existing AC Transformer in place. Do not make the mistake of trying to use the existing transformer. You have two (2) options when it comes to powering the LTEM-PA or LTEM-PV. You can use the included power supply, making sure to observe proper polarity with the power wires, or you can wire it so that the communicator receives all its power from the alarm panel. If you choose the latter option, be sure to calculate the current draw for the communicator correctly, and if you decide to leave the battery out of the LTEM-P Series device, turn off the radio's Low Battery Reporting.

Tip 2: Installing A WIFI Module

If you want to add support for WIFI to your LTEM-P module, you can add the PROWIFI module. When the PROWIFI module is installed, the ethernet connection becomes unavailable, so you can only use one or the other of these, but not both. If you want to add both WIFI and Z-Wave Plus capabilities to your system, then you can choose to install the PROWIFIZW.

Using the PROWIFIZW can add Z-Wave support in a situation where it would otherwise be unavailable, such as when using the LTEM-P with a non-VISTA panel. The PROWIFIZW cannot be used as a secondary controller, so it can't be used to extend the range of another controller such as the Tuxedo or VAM. Using the PROWIFIZW also doesn't give you an option to create scenes through Total Connect 2.0, only manual control of Z-Wave devices is available.

Tip 3: Always Default the Communicator

We've found, through painful experience, that it is a good idea to always default the LTEM-PA or LTEM-PV once all the wiring is completed, prior to account creation and activation. To default, hold down the red button on the upper right side of the main communicator board for at least 20 Seconds. The LEDs on the communicator should begin going through their initial power-on sequence. This is how you can tell the default has completed.

Once the communicator has booted completely up, then do one last power cycle. Do this by unplugging the transformer and disconnecting the red battery lead. If the communicator is being powered completely by the panel, simply power the panel down and back up by unplugging its transformer and backup battery. If the communicator battery is still connected though, be sure to disconnect this battery as well to completely power the communicator off. Wait about 30 seconds, then power back on as you normally would. For VISTA panels, plug in the transformer, then the battery. If the communicator has its own DC Power Supply, plug in the communicator battery, then plug in the power supply. Now you can proceed with programming and activation.

An announcement on the AlarmNet360 page shows that they will send a remote reset command to some LTEM-PA, LTEM-PV, LTEM-PIA, and LTEM-PIV radios. This will occur today, Friday 04/15/22 between 2:00 pm - 3:00 pm ET. This may cause a trouble condition, and queued alarm reports could be sent.

It's unclear why this is being done. After a successful reset occurs, the radio will send an "E339-EXP. Module Power ON / Reset" message to the monitoring station. If the radio was in comm failure prior to the reset and any unsent alarm signals were queued, this reset may cause those alarm messages to be sent. These signals would show up immediately following the E339 signal at the central station. We assume this would also cause the same alarm messages to show up in Total Connect 2.0, and to be sent as notifications.

In addition, depending on how the panel is programmed, this event may cause the panel to display a bF or Check 103 message, and could also cause trouble beeping from the keypad. Disarming the system twice should clear the message and return the system to its normal state.

A convenient option when using a 3G or CDMA radio on a VISTA panel was the ability to share a single transformer for both devices. This was possible because both units used AC power. The new LTEM-PA and LTEM-PV communicators use a DC transformer, so attempting to share will cause issues.

The Resideo LTEM-PA and LTEM-PV dual-path communicators are a part of the new ProSeries lineup. In addition to these communicators, the Honeywell Home PROA7 and Honeywell Home PROA7PLUS and the Resideo PROA7C and Resideo PROA7PLUSC help to make up the ProSeries. These products may seem to make strange bedfellows, but the modular design shared by the All-in-One (AiO) panels and the stand-alone communicators is no accident. With some modules, such as the LTE communicators being shared between the two product lines. This is one reason why the LTEM-PA and LTEM-PV use DC power, rather than AC.

It's a natural assumption to make, thinking that since the older communicator from a particular manufacturer was an AC step-down transformer, the new communicator would employ a similar design. But in this case, that assumption can get you into a lot of trouble. Attempting to keep the original transformer from the 3G or CDMA communicator in place, and just connecting the LTEM-PA or LTEM-PV in place of the older one, can damage the VISTA panel, the transformer, or both.

The symptoms seen by Resideo Tech Support, when this mistake has been made are as follows:

• The transformer is damaged. Once this occurs, the VISTA panel will show an AC loss condition. Naturally, the next step is to replace the bad transformer with a good one. This can lead to the second symptom that has been seen.
• The VISTA board is damaged. Once the damaged transformer is replaced with a new one, feedback on the panel's power circuit causes one or more of the diodes on the VISTA board (above terminals 1 and 2) to become damaged. This can cause a burning smell and may even cause the panel to catch fire in a worst-case scenario.

In the image below, you can see a damaged diode. This area of the printed circuit board is just above Terminal 1 and Terminal 2 on a VISTA panel.

It is possible for the LTEM-PA or LTEM-PV to receive power from the panel so that only one transformer is required in the setup. However, the power comes from the 12 Volt DC auxiliary power output, not the transformer. You can see how to properly configure that setup in this helpful FAQ.

Alarm.com announced on Friday, October 22, 2021 that they plan to discontinue sales of the Concord 4 Dual-Path VoLTE Module and Gateway at the end of October. Interlogix, which is now owned by UTC (United Technologies Corporation) stopped making the Concord 4 panel in late 2019.

There were two (2) VoLTE Dual-Path communicators formerly offered by Alarm.com. The Alarm.com CD-411-US-AT AT&T LTE version, and the Alarm.com CD-421-US-VZ Verizon LTE version. Both of these modules have been on backorder for some time during the global chip shortage, which may have played a part in the decision to discontinue them.

As of now, there is still a Verizon LTE cellular-only communicator available for the Concord 4 panel. The Interlogix GE 600-1053-LTE-VZ connects to the Verizon LTE network for fast and reliable delivery of alarm signals and Alarm.com notifications. With Alarm.com service, the user also has the ability to review status and send alarm system commands remotely using the Alarm.com app or website.

UPDATE 10/26/21! We've discovered that the Interlogix GE 600-1053-LTE-VZ is not available from any of our vendors. We haven't seen an official discontinuation notice, but it seems it may have been. This means that currently, we can't offer any new LTE communicators for the Interlogix/GE Concord 4. For alarm reporting only, the Resideo LTEM-PA or LTEM-PV with the Resideo PRODCM Dialer Capture Module can be used.

The Concord 4 panel is not one that Alarm Grid sells. However, for those users with a Concord 4 in the field that is still working just fine, an updated communicator allows them to continue using a system they're comfortable with, while taking advantage of newly introduced features.

With a subscription to Alarm.com and one of the Verizon LTE communicators, not only can the user view the status of their system, arm and disarm remotely, and receive text, email, or push notifications on alarm events, but they can also add the convenience of Z-Wave functionality to the system. Z-Wave is a communications protocol that allows various devices in your home or business to communicate with the main system to do things such as turn on lights, set the thermostat to a particular temperature based on a Geo-Fence or on the armed status of the panel, and many more options. The Concord 4 panel just needs to be on version 4.0 or higher to support the use of the 600-1053-LTE-VZ communicator.

What do you think about Alarm.com discontinuing these modules? It's only been about a year since they were introduced. Do you think the global chip shortage led to the demise of the Concord 4 Dual-Path communicators? Leave a comment below and we can discuss further. As always, we look forward to hearing from you.

DSC PowerSeries NEO users should be pleased to learn that a new firmware update is available for their system communicators. Firmware Upgrade Version 191a offers improvements for Over-The-Air (OTA) connectivity and stability improvements. It also corrects some minor issues that were present.

Firmware Upgrade Version 191a is applicable to both DSC PowerSeries NEO and DSC PowerSeries PRO Systems. For DSC PowerSeries NEO users, the firmware update is technically optional, but still recommended. In order to receive the update, you must have it pushed down manually to your alarm panel from the Alarm.com servers. Assuming that you have internet connectivity set up for your PowerSeries NEO Alarm System, you should not incur any fees as part of the updating process.

Alarm Grid monitored customers with PowerSeries NEO Security Systems can request the update by emailing support@alarmgrid.com. We will work on pushing the update down to your panel at our earliest convenience upon receiving your request. This is also a great email to use if you have any further questions about alarm systems, or if you are interested in starting new monitoring service with Alarm Grid. Remember that we are here to check your emails from 9am to 8pm ET M-F. We look forward to hearing from you!

Hi DIYers! We are excited to announce that we now have dual-path communicators available for the Interlogix Simon Series Systems. Compatible panels include the Simon XT (1.3+), Simon XTi, Simon XTi-5 and the upcoming Simon XTi-5i System. There are AT&T LTE and Verizon LTE options available.

If you are an Interlogix Simon user, then you know how important it is to add an alarm monitoring communicator to your system. These systems don't come with an integrated communicator, and you need to add one if you want reliable alarm monitoring service and connectivity with the Alarm.com platform. By accessing Alarm.com, you can arm and disarm your system, check current system status, control Z-Wave devices, and view your ADC Cameras from virtually anywhere in the world.

What's great about these new communicators is that they utilize dual-path connectivity across an LTE network and a local IP network. In other words, you get the ultra-fast speeds of IP monitoring, plus the full reliability of cellular connectivity. If one path goes down or becomes unavailable, the other path will be there to back it up. This is ideal for situations where the internet goes down or when an electrical outage takes your router offline. Your system will still have cellular service to fall back on.

You get more than just trustworthy dual-path connectivity with one of these new communicators. They are also effective Z-Wave Plus controllers that you can use to start building a complete smart home network. You can add classic Z-Wave and Z-Wave Plus devices to the panel for use with Alarm.com. This includes the ability to start creating smart scenes for automatic operation based on a set schedule or with certain system events. We recommend using Z-Wave Plus devices for optimal battery life and wireless signal range.

It's important to note that these are LTE and IP dual-path communicators. If you aren't aware, LTE stands for "Long-Term Evolution", and cellular service providers have promised to support their LTE networks well into the very distant future. By upgrading to one of these modules, you are ensuring that your Interlogix Alarm Panel can receive fast and reliable monitoring service for many years to come.

These dual-path communicators come in AT&T LTE and Verizon LTE options. Remember, this has nothing to do with the cellular service provider for your smartphone. You can certainly have an AT&T Smartphone and use a Verizon Communicator for your alarm system, or vice-versa. You should simply choose whichever service provider works more effectively in your area. The new communicators are as follows:

• Alarm.com XT-511-US-DP-AT - AT&T LTE & IP Communicator
• Alarm.com XT-511-US-DP-VZ - Verizon LTE & IP Communicator

Remember, you will need a Self Gold Level Plan or higher from Alarm Grid to use these communicators. This is the only way to gain access to the Alarm.com platform for security and smart home control. More information about our alarm monitoring plans is available on our alarm monitoring page.

If you have any questions about these new Interlogix Dual-Path Communicators, please reach out to us. The best way to contact us is to email support@alarmgrid.com. We will check this email at our earliest convenience and reply back as soon as possible. You may also call us at (888) 818-7728 during our regular business hours of 9am to 8pm EST M-F. We look forward to hearing from you.

Choosing an alarm monitoring plan can feel overwhelming with options for central station service, self-monitoring, automation, and video surveillance. This guide explains Alarm Grid monitoring plans clearly so you can compare features and choose the service that fits your home or business.

What is Alarm Monitoring?

Alarm monitoring is a service that allows a security system to send signals when alarms, troubles, or other system events occur. Depending on the plan, those signals may go to a central monitoring station, an interactive service platform where it is forwarded to the end use, or both.

Without monitoring, a system can still sound sirens locally. But if you are away from the property, a local alarm may not be enough to alert you or request help.

Monitoring can provide off-site alerts, remote system control, and automatic emergency dispatch. Some centrally monitored customers may also qualify for a homeowner's insurance discount with a Certificate of Alarm.

What is a Central Monitoring Station?

A central monitoring station is a facility where trained dispatchers respond to incoming security system alarms and other signals. When an alarm signal is received, the dispatcher can see the alarm type and the location of the protected premises.

Alarm signals may include burglary, fire, medical, carbon monoxide, panic, and other emergency events. The dispatcher follows a set of instructions for the account, including attempting to contact the end user, before requesting dispatch, unless account notes or local rules require a different procedure.

In most cases, the central station will attempt to verify the alarm before dispatching authorities. The user may need to answer the phone and provide their false alarm passcode to cancel a false alarm.

If the user cannot be reached, or the user contacted cannot provide the correct false alarm passcode, or gives a duress code, the central station operator will request dispatch. Some areas may also have special rules, such as verified response requirements.

Alarm Grid customers in the United States who choose central station monitoring are connected with Criticom Monitoring Services. CMS operates three networked monitoring centers in Florida, New Jersey, and California. If one center is affected by a major event, signals can be rerouted to another center.

Our Canadian customers who choose central station monitoring have their signals sent to Rapid Response Monitoring Service. You can learn about Rapid Response in their own words: "Deploy the definition of multi-redundancy. Two bicoastal, hardened Command Centers and one secure, hosted Customer Care Center stand ready to serve you 24/7/365. Our headquarters Command Center, home to our original monitoring & data center, is based in Upstate NY. Our redundant Command Center, full-load capable monitoring & data center, is based in Southern California. Our operations branch out in a hub-and-spoke model to include our secure, hosted Customer Care Center in Southern Nevada".

In addition to their load sharing capabilities, Rapid Response also has impressive power capabilities: "Through our digitally-controlled CATERPILLAR diesel generators, Rapid Response has enough private power generation at each of our Command Centers to equivalently power 30 homes for 30 days. Power generation is ensured by months of on-site fuel storage in independent redundant tanks.

Electricity runs through multiple enterprise-scale UPS (uninterruptible power supply) battery banks with digital switching controls to eliminate gaps between grid failure and generator spinup. Combined with quad-bus wiring to every piece of equipment in our facilities, power failure is practically impossible."

What is Self-Monitoring?

Self-monitoring connects the system to an interactive service platform without connecting it to a central station. Instead of a dispatcher responding to alarms, the end user receives an alert via email or push notification and contacts the authorities if needed.

Self-monitoring is often used by customers who want app access and notifications, but do not need central station dispatch. It can also be useful for customers outside areas where central station service is available, and for customers in areas where verified response is required or where false alarm fees are high.

Self-monitoring does not provide a Certificate of Alarm. Because no central station is involved, it is less likely to qualify for a homeowner's insurance discount.

What is an Interactive Service Platform?

Interactive service platforms allow users to receive alerts, check system status, and control compatible systems remotely. Alarm Grid customers commonly use Total Connect 2.0, Alarm.com, or Telguard, depending on the system and communicator.

Total Connect 2.0 and Alarm.com can provide remote arming and disarming, text and email alerts, push notifications, Z-Wave automation, and video features. Available features depend on the monitoring plan and installed equipment.

Let's Discuss Monitoring Plans!

Alarm Grid monitoring plans are divided into Bronze, Silver, Gold, and Platinum tiers. Each tier has a central station version and a self-monitoring version.

Central station plans are often called Standard plans. These plans connect the system to a central monitoring station for emergency dispatch. Self-monitoring plans provide app access and alerts without central station dispatch. We also offer a plan for cellular alarm monitoring (central station monitoring via cellular with no app access), and one for video-only monitoring (video-only self monitoring with no alarm panel).

Each monitoring plan covers one security system. If you need monitoring for a second system or a second alarm control panel, you will need a separate monitoring plan.

Quick Plan Comparison

Bronze & Self-Bronze

The Bronze level is the most basic Alarm Grid monitoring tier. Standard Bronze provides central station monitoring using landline or internet communication. This plan offers NO ACCESS to an interactive service platform.

Self-Bronze provides basic interactive service without central station dispatch. It can support email, text, and push notifications to the end user, IP communication (WIFI or Ethernet), and remote arming or disarming on systems that support it. Self Bronze provides NO ACCESS to remote control of automation devices.

Bronze plans are best for customers who want basic monitoring or basic remote alerts at the lowest monthly cost. Standard Bronze is $15 per month, and Self-Bronze is $10 per month.

Silver & Self-Silver

Silver plans add interactive monitoring features and remote smart home automation. This level is a good choice for users who want to control their system from an app and manage compatible Z-Wave devices remotely.

Standard Silver includes central station monitoring, internet monitoring, remote arming and disarming, alerts, and remote home automation. Self-Silver provides interactive service and automation without central station dispatch.

Silver plans are best for compatible systems using internet communication where remote access and automation are important. Standard Silver is $25 per month, and Self-Silver is $15 per month.

Gold & Self-Gold

Gold plans add cellular communication. Cellular monitoring is generally more reliable than internet-only monitoring because it does not rely on the property's internet service.

Customers with compatible equipment can also use dual-path communication with both internet and cellular. This provides added redundancy when supported by the system and communicator.

Alarm.com service requires a monitoring plan that supports cellular communication. Customers using an Alarm.com-compatible system should expect to choose Gold, Self-Gold, Platinum, Self-Platinum, or another qualifying cellular plan.

Gold plans are a strong option for customers who want cellular reliability, Alarm.com service, or dual-path monitoring. Standard Gold is $35 per month, and Self-Gold is $25 per month.

Note: Alarm.com Image Sensor support may be available with compatible systems and services.

Platinum & Self-Platinum

Platinum plans add video surveillance features. These plans allow users to view compatible security cameras through Total Connect 2.0 or Alarm.com.

Video features may include live viewing, saved clips, and remote access through the appropriate mobile app. Available camera features depend on the selected service, installed cameras, and account settings.

Platinum plans are best for customers who want security monitoring, remote automation, cellular service, and video surveillance together. Standard Platinum is $45 per month, and Self-Platinum is $35 per month.

Other Monitoring Plans

Alarm Grid also offers alternative monitoring plans for customers who do not fit into the standard Bronze, Silver, Gold, or Platinum structure. These include the Cellular-Only Plan and the Video-Only Plan.

The Cellular-Only Plan is similar to Standard Bronze, but it allows for cellular monitoring service. It connects the system to the central station without adding interactive service features such as app control, remote automation, or video.

This plan is useful for customers who want cellular reliability and central station dispatch, but do not need an interactive app. The Cellular-Only Plan is $25 per month.

The Video-Only Plan is for customers who only need video service through Total Connect 2.0 or Alarm.com. A security system is not required for this plan.

Customers may also combine Video-Only service with another compatible monitoring plan to add cameras to an existing account. The Video-Only Plan is $15 per month.

Hi DIYers! Unfortunately, we have to keep this news brief, as we are currently preparing for ISC West 2019 in Las Vegas, NV. But a new dual-path communicator from Resideo for their VISTA Systems is now available. Presenting, the all-new Honeywell LTE-IV Verizon LTE Dual-Path Communicator!

The Honeywell LTE-IV uses a hardwired ethernet cable to connect a VISTA Panel to an IP network. If the internet goes down, it will have the ultra-fast and reliable Verizon LTE Cellular Network as a backup. Either way, the system will remain connected with the AlarmNet 360 Servers and the Total Connect 2.0 Service.

This release is huge, as this is currently the only dual-path communicator for a VISTA System that can connect with an LTE Network. Before this, the VISTA Panels had to rely on the Honeywell LTE-XV and Honeywell LTE-XA modules, which had no IP capabilities. Now with the Honeywell LTE-IV, VISTA owners have a dual-path LTE option that will keep their system connected for many years to come!

Note that the Honeywell LTE-IV connects with the Verizon LTE Network. We expect a similar AT&T communicator to be released at some point. You can purchase the Honeywell LTE-IV from the Alarm Grid website. If you have any question, please email support@alarmgrid.com or call (888) 818-7728 from 9am to 8pm EST M-F.

Alarm Grid will post more information about the Honeywell LTE-IV as it becomes available.
