7. COMMUNICATION
7-1 Dry Contact Communication Terminal
The “Dry Contact” terminal is the interface for two Form C
relays. The relays are used for switching the voltage provided
by the user’s external alarm system.
One contact set is for “DC Abnormal” and the other one is for
“FAULT”. When alarms in each classification trigger, the relay
switches state. (Ref: Sec. 6-3 Alarms) Connection to the
terminal should be made to external sensor circuits with
appropriate sized wire. The terminal can support 5A / 250VAC
in either NC or NO configurations.
