How Do I Upgrade a DSC Impassa to Use LTE?
You can upgrade a DSC Impassa to use LTE by installing and activating a compatible LTE cellular communicator for the system. The best communicator to use is the DSC TL8055LTVZ, which connects across the Verizon LTE Network. The Impassa will use this module to communicate with Alarm.com.
Like any alarm system, the DSC Impassa needs a communicator for monitoring service. With the impending 3G and CDMA sunset, only LTE communicators can be activated for connectivity with Alarm.com as of late 2020. Luckily, the Impassa has a great LTE communicator option in the DSC TL8055LTVZ. Since this is an LTE communicator, you will be able to keep your Impassa monitored well into the very distant future. Verizon has publicly stated that they plan on maintaining support for the LTE network, even as 5G networks come into fruition.
You will need a monitoring plan to activate the DSC TL8055LTVZ. If you get monitoring service with Alarm Grid, then you can choose between a Gold Level Plan and a Platinum Level Plan. Both self-plans and central station plans will work fine. Choose the best plan for your needs. We also offer a Cellular-Only Plan, which is good if you only want central station service, without the interactive and remote access features of Alarm.com. You can learn all about Alarm Grid monitoring plans in this comprehensive blog post.
The DSC TL8055LTVZ is a dual-path communicator, meaning that it connects across both IP (internet protocol) and cellular. Alarm.com requires the cellular portion of the communicator to be activated and registered, but internet is technically optional. However, most users will activate for both IP and cellular, because it never really hurts to have multiple communication paths available. Just remember that the Impassa System must be running at least Firmware Version 1.3 to support the communicator. If your Impassa is on a lower firmware, then you may want to consider replacing the panel. Finally, make sure you get adequate coverage from the Verizon LTE Network. Check coverage maps if you aren't sure. A cellular antenna or cellular amplifier may be added to boost signals.
For this FAQ, we will assume that the Impassa is on Firmware Version 1.3 or higher. Complete the following steps to upgrade a DSC Impassa to LTE:
1. Power down the panel. Always power down the system before installing a cellular communicator. Open up the panel, and disconnect the backup battery. Then unplug the transformer from the wall outlet. You may need a screwdriver to unplug the transformer if it is is screwed into the wall outlet. The panel should power down.
2. Install the communicator. With the system fully powered down, remove the old communicator, if applicable. Then install the new DSC TL8055LTVZ Communicator. Refer to the instruction manual for the communicator for more info on how to complete the upgrade process. Make sure to note the IMEI number on the communicator, as you will need it when activating. The IMEI should be found on a sticker somewhere on the unit, or on the product packaging.
3. Power on the panel. Connect the backup battery first. You can then close the panel. Then plug the transformer back into the wall outlet. Reapply the set screw for the transformer if applicable. The system should power on.
4. Activate for monitoring. The communicator must be activated for monitoring service. If you are setting up service with Alarm Grid, then an activator will reach out to you at your scheduled activation slot. You should have the communicator installed inside the system prior to this time. Please follow these tips to ensure that your activation goes as smoothly as possible.
