The LTEM-PA/LTEM-PV Allow Non-Honeywell Panels to Access TC2

Until now, only alarm systems manufactured by Resideo, Honeywell Home, or Honeywell could be used with Total Connect 2.0. That changes with the new LTEM-P Series communicators. Some DSC and Interlogix panels can now be connected to and used with TC2. A supplemental wiring guide is provided.

The LTEM-PA AT&T LTE Communicator, and the LTEM-PV Verizon LTE Communicator available from Resideo can be used to send alarm signals on behalf of all the same VISTA panels that were compatible with the older AlarmNet communicators such as the Honeywell LTE-IA, and the Honeywell LTE-IV. In addition, certain versions of some of these panels can also be used with Total Connect 2.0 Remote Services when one of these communicators is attached to it.

With the release of the LTEM-P Series communicators, DSC PC1616, DSC PC1832, and DSC PC1864 panels can support both reporting through the communicator when it is connected to the panel's keypad bus and integration with Total Connect 2.0. In addition, Interlogix NX8E, NX-4V2, NX-6V2, and NX-8V2 panels can also be used with the LTEM-P Series communicators to both send signals, and integrate with TC2.

With the DSC PC Series panels, this is purely a keypad bus connection. The communicator's RX, TX, and Ground terminals will connect to the DSC panel's Green, Yellow, and Black keypad bus terminals. On the Interlogix NX Series panels that are supported, there is a connection to RX on the communicator from the terminal marked DATA on the panel's keypad bus. COM from the NX Series panel will connect to GND on the Communicator. In addition to this, the LTEM-P Series communicator will require a Resideo PRODCM Dialer Capture Module, which will connect to the panel's Tip and Ring terminals. The PRODCM will be installed inside the communicator. Panel signals are sent via the PRODCM, and Data Bus information for Total Connect 2.0 is sent from the bus.

There are some programming options that will need to be configured properly, for example the NX panel must be set to report in Contact ID format. In fact, all signals for both panel types will be sent to the monitoring station using Contact ID. The wiring connections should be made while both the panel and communicator are powered down. The alarm panel is powered up first, and all troubles, faults, and alarms must be cleared. Once they are, power up the communicator and it should begin to scan the panel's bus for zone information. This process can take up to ten (10) minutes.

This is not meant to be a step-by-step guide to setting up this feature, it's just an introduction to the feature for those who may not be aware that it is available. We offer an FAQ for using the DSC panels with TC2 here. If you have one of the compatible DSC or Interlogix panels, and you are considering using it with one of the LTEM-P Series communicators, check out the Resideo LTEM-P Series Installation Guide, the Resideo Supplemental Install Guide for Non-VISTA panels, and for those using a compatible Interlogix NX-Series panel, also check out the Resideo PRODCM Install Guide. We have not yet had an opportunity to create our own in depth FAQs for this process on the Non-VISTA panels, but we will get to those in the near future.

Have any thoughts about Resideo and Honeywell Home finally embracing the use of their communicators with competitor's panels? They offered a dialer capture module in the past, but it installed outside the communicator and was somewhat unwieldy. Leave a comment below and tell us what you think. We always look forward to hearing from our readers!
