Who can monitor an LTEIA-ADT?
Only ADT can monitor an LTEIA-ADT. The LTEIA-ADT is a proprietary dual-path communicator that only works with ADT services. It connects with the AT&T LTE Network and a local IP network through ethernet. A new communicator is needed to use the existing system with a different alarm company.
ADT uses many proprietary communicators with their monitoring services. One of which is the LTEIA-ADT. This communicator is basically the same as the Honeywell LTE-IA Dual-Path Communicator. The only difference is that the the LTEIA-ADT has been designed so that it will only work with monitoring services from ADT. If you try to bring the LTEIA-ADT to a different monitoring company, such as Alarm Grid, it will not work. Meanwhile, the LTE-IA can be used with any monitoring company that is registered with AlarmNet.
If you want to leave ADT and you have an LTEIA-ADT, then it doesn't necessarily mean that you need to replace your entire security system. The LTEIA-ADT is used with the same Honeywell VISTA Panels that are used with the LTE-IA. All you will need to do is remove the LTEIA-ADT and replace it with a non-branded communicator that can be used with a different monitoring company. Obviously, the LTE-IA is the most likely candidate for this task. But there are other communicators you can choose as well. The LTE-IV will offer service from the Verizon LTE Network instead of the AT&T LTE Network. And the LTE-XA will offer AT&T LTE service but no IP connectivity. Losing IP connectivity isn't a huge problem, as cellular is more reliable.
The process for replacing an existing ADT Communicator is actually very easy. The first step is to power down the panel by disconnecting the backup battery and unplugging the transformer. Next, you should disconnect the LTEIA-ADT. It is recommended that you only disconnect the wires at the module itself. You can keep the wires connected to the panel so that they can be used with the new communicator. You must also physically remove the LTEIA-ADT from the panel. The new communicator can use the same wires and connect in the same location. From there, you can activate the communicator for alarm monitoring service.
You might also want to take this opportunity to replace the PROM Chip. This will make it easier for your new monitoring company to program your system. Replacing the PROM Chip is generally seen as an optional step, but it can make your life easier in the long run. But as long as you have an ADT Safewatch PRO 3000 System with a PROM Chip of Version 9.12 or higher, then you will still be able to use Total Connect 2.0 without a replacement. If you are looking for a replacement PROM Chip, then we sell VISTA 20P PROM Chips on our site that can be used with an ADT Safewatch PRO 3000. We also sell some kits that include both a new communicator and replacement PROM Chips. The most notable is the Honeywell LTEIA-TC2, which includes the LTE-IA and PROM Chips for 15P and 20P Systems.
Keep in mind that there may be complications when replacing the PROM Chip for an existing ADT System. There are too many considerations for us to provide a complete guide here. For that reason, it is strongly recommended that you contact Alarm Grid directly if you are considering a PROM Chip replacement for your ADT Security System. We will ask that you include the specifics of your ADT Alarm System when contacting us. This will include the system model number, what communicator you currently have, and the revision number of your current PROM Chip. You can reach Alarm Grid by emailing email@example.com or by calling (888) 818-7728 during our regular business hours of 9am to 8pm ET M-F.
