The module can signal alarm, trouble, and supervisory conditions. The Wiring the D185 figure,
24 shows the module being used to signal alarm and trouble conditions only. With a third relay
(available from the eight-relay expansion module) and an additional leased line, supervisory
conditions can also be signaled.
In the example in the Wiring the D185 figure, Relay 1 must be programmed to operate on
Alarm (Zone 63) and Relay 2 must be programmed to operate on Trouble (Zone 62). Program
Input 4 to operate as a Supervisory point. Any alarm causes the voltage to the monitoring
station to be interrupted. Placing the D185 in test mode causes a SUPERVISORY TROUBLE.
