Customers who want the latest dual-path communicator from Honeywell look no further than the Honeywell Home LTEM-PV. This communicator from Honeywell Home works with all Honeywell VISTA Systems that support ECP mode. It has cellular service through the Verizon Cat M1 Network and IP connectivity.
For those users who are familiar with the earlier Honeywell LTEM-XV, the Honeywell LTEM-PV is a somewhat similar AlarmNet Communicator. Both the LTEM-XV and the LTEM-PV offer cellular communication using the cutting edge Verizon LTE Cat M1 Network. These communicators differ in that the LTEM-XV is cellular-only, but the LTEM-PV offers IP connectivity in addition to cellular. By setting up both internet and cellular, what is referred to as a dual-path system, your alarm will stay monitored if one communication pathway goes down or becomes unavailable. While you can certainly choose to set up just one path (internet OR cellular), virtually all buyers of the LTEM-PV will opt for dual-path connectivity as it gives the greatest opportunity for the alarm system to communicate successfully in the event of an emergency. If you want cell-only, then the aforementioned LTEM-XV is recommended. If you want internet protocol (IP) only, and you don't want the option to change your mind and add cellular at a later time, then the Honeywell 7847i may be a good option for your VISTA System.
An important thing to note about the Honeywell Home LTEM-PV is that it is an AlarmNet Communicator. This means that it connects with the Resideo AlarmNet Servers for the transmission of alarm signals when a customer has monitoring service. When AlarmNet receives a signal from the VISTA System, it can then forward the signal to the Total Connect 2.0 interactive security notification and automation platform, as well as a central monitoring station, depending on the monitoring plan the customer is using. Some alarm monitoring plans include service with Total Connect 2.0 (TC2) only, some are central station only, and others include both TC2 and central station service. Check with your monitoring provider to determine which monthly monitoring plan is right for you.
Note that a VISTA-15P or VISTA-20P needs a PROM Chip of 9.12 or higher to support TC2. You can get PROM Chip upgrades for the 15P and for the 20P if needed. Meanwhile, all versions of the VISTA-128BPT support TC2, and any VISTA-250BPT running Version 10.3 or higher will support the service. While the VISTA-10P can still use the LTEM-PV for central station monitoring, it cannot support Total Connect 2.0. Please see this FAQ for more information on checking and replacing PROM Chips.
The ability to communicate through internet is a bit unique with the LTEM-PV. While most IP communicators for Honeywell VISTA Systems are wired ethernet only, the LTEM-PV has changed things up. In the past, users with VISTA systems who wanted to use an IP based communication path were forced to use a wired ethernet connection. If WIFI was desired, or in some cases needed, then the only way to achieve a WIFI connection was by using an ethernet to WIFI bridge. Alarm Grid offers one of these devices in the Alarm.com ADC-W110. These devices usually connect to an electrical outlet near the communicator. The ethernet cable from the communicator is connected to the adapter, and then from the adapter to the router the connection uses WIFI, usually set up via WPS (WIFI Protected Setup). This connection is vulnerable to AC Power outages, though. The LTEM-PV now has the ability to have a WIFI-capable module installed directly into the communicator so that it can connect to WIFI natively, without any type of ethernet to WIFI converter. The modular design means that the LTEM-PV doesn't carry the UL-985 Listing for Residential Fire. If you require a communicator with this listing, you'll need to look to the Resideo LTEM-PIV.
New to the LTEM-PV is the ability to set up a wireless WIFI connection path by using one of the ProSeries WIFI Modules. Either the Honeywell Home PROWIFI (WIFI only) or the Honeywell PROWIFIZW (WIFI & Z-Wave Plus) can be added to the LTEM-PV to allow support for a WIFI connection. If you opt to use one of the ProSeries WIFI Modules to connect the LTEM-PV to the internet, then the setup can either be configured by your alarm installer using the AlarmNet 360 website or the AlarmNet 360 App. This connection can also be configured by the end-user through Total Connect 2.0. Both of the ProSeries WIFI Communicators support 2.4 GHz WIFI networks only. The ProSeries WIFI devices do not support using 5 GHz WIFI networks.
Please Note: It is not possible to use both a wired ethernet connection and a ProSeries WIFI Module simultaneously with the Honeywell LTEM-PV. Only one (1) of those compatible internet connection options can be used at any given time.
Another new and exciting feature of the LTEM-PV is its ability to be used with Non-Honeywell manufactured panels. The communicator can be connected to certain legacy DSC (PC1616, PC1832, PC1864) and Interlogix panels (NX-8 and NX-8V2, NX-6V2, and NX-4V2) using the panel's keypad data bus. For the supported panels, this introduces the ability to interface Non-VISTA hardwired panels with Total Connect 2.0 for the very first time! When a PROWIFIZW is used with the LTEM-PV, the Total Connect 2.0 account can even support the use of Z-Wave devices, and Smart Scenes. For information about the models supported, and how to wire them, check out the Installation Guide, starting on Page 11. For other Non-VISTA panels where a keypad bus connection is not supported, Honeywell offers a new and improved PRODCM dialer capture module. This device will allow the LTEM-PA and LTEM-PV Series communicators to be used with any panel that can report in Contact ID Format, and supports a phone line dialer.
Something else that's new to the LTEM-P Series communicators is the fact that a wiring harness is supplied for the data bus connection. The harness assumes that the LTEM-PV will be mounted right on top of the metal enclosure. The harness provides a 3-Wire connection, Data In (Green), Data Out (Yellow), and Ground (Black). When the harness is used, it connects to TB1, located right next to the terminal block (see page 10 in the Installation Guide). If the wiring harness is too short, for those installations where the LTEM-PV is not going to be mounted right on top of the alarm panel's metal cabinet, then separate wires can be run between the panel's terminal block and the communicator for Data In, and Data Out. If the wiring harness will not be used, then either 18-gauge 4-conductor, or 22-gauge 4-conductor wire can be used. The longer the wire run, the thicker the wire gauge should be. Again, see the Installation Guide for complete information. If you find that you need to run wire, but don't need a whole box of alarm wiring, we offer 22-gauge 4-conductor wire in 10', 15', and 25' pre-cut sections.
There is no wire supplied with the LTEM-PV for a connection to its transformer. You must use your own. Most users find that 18-gauge 2-conductor wiring works perfectly for this. The unit gets its primary power from the included DC transformer. The fact that the transformer is DC means that the LTEM-P Series communicators cannot share a transformer with the alarm panel. This has been possible with some communicators in the past. It also means that you must be careful to observe proper polarity when connecting the power wires to both the transformer and the communicator. It is possible to power the communicator using the panel's auxiliary power. You can see how to wire that in this FAQ. Inside the LTEM-PV is its backup battery, which comes included. The LTEM-PV measures 9.1" X 9.1" x 2.2" (23.2cm x 23.2cm x 5.7cm). It weighs 1.5lbs (700g) without its backup battery, or 3.3lbs (1500g) with the battery. It includes LED lights to indicate current device and connection status. The unit supports tamper detection to let the system know if someone tries to open or disable the communicator. Note the device's current draw of 70 mA when idle, which rises to 386 mA when used with cellular AND WIFI through a PROWIFI/PROWIFIZW. The maximum current draw will be less if wired ethernet is used instead.
