Power Connections and Options
Powering the Communicator
There are three ways to power the communicator (see illustrations below):
Standard Installation – The communicator is powered by the supplied AC plug-in transformer.
ULC Commercial Fire and Burglary Compliant Installation – The communicator must be
powered by the control panel.
Shared Transformer Installation – In this installation the supplied AC plug-in transformer may
be used to power both the communicator and the control panel under the following conditions:
You must use the Honeywell 1361-GT Transformer.
This configuration ONLY applies to the VISTA-15P, VISTA-20P control panels when used
with the LTE-I Communicator.
DO NOT use this configuration with any other control panel.
This configuration has not been evaluated by UL.
For all installations, the control panel ground (GND) must be connected to TB1-4 GND on the
communicator. In addition, if using ECP communication, you must connect the +12VDC AUX
voltage output on the control panel (9.6V-13.8V typical) to TB1-3 on the communicator.
