IGSMHS Installation and Setup Guide
Wiring for ECP, 4204 and Two-4204 Modes
Most Honeywell control panels support ECP data communication. Check the Installation
and Setup Guide for the control panel you are using to see if it supports ECP communication.
Connect the IGSMHS to a compatible Honeywell VISTA control panel's ECP terminals, in
parallel with keypads and other peripheral devices such as RF receiver, VIP module, etc.
Wire length / gauge limitations are the same for the module as they are for keypads and other
peripheral devices. To wire the module for ECP or 4204 modes, see Figure 2-2 and make the
following connections:
Wiring for Zone Trigger Mode
To trip a zone using a positive trigger, the voltage level must be:
6V or greater = positive trigger. (Levels above +14V may cause damage to the unit.)
4V or less = restore.
To trip a zone using a negative trigger, the voltage level must be:
4V or less = negative trigger.
6V or greater = restore. (Levels above +14V may cause damage to the unit.)
NOTE: Remember to program the communications module zone for the desired trigger type.
Connect a wire from the triggering source (bell output, voltage trigger, etc.) of the control
panel to the zone input of the module, and connect a common ground between the module
and control panel. Examples of zone connections follow:
