4.8.5 Relay Output Connections
Five “voltage free” relay outputs (TB2 – TB6) are provided and can be configured for a variety of uses.
 Alarm - activated on device alarm conditions and “Function” programmed logics. The relay
is turned off during a ALARM disable condition.
 Sprinkler - activated on device alarm conditions and “Function” programmed logics.
 Fault - activated on all fault conditions and “Function” programmed logics. The relay is
turned off during a FAULT disable condition.
 Isolate - activated on all isolate conditions and “Function” programmed logics.
 Battery Fail - activated on battery fail conditions and “Function” programmed logics.
 Mains Fail - activated on a mains power fail condition and “Function” programmed logics.
 Warning System - activated on evacuation, device alarm conditions and “Function”
programmed logics. If the activation of this relay is due to an evacuation condition, then the
relay is turned off during an Alarm (sounder) disable or Alarm (sounder) silence condition.
 Ancillary - activated on device alarm conditions.
 General Purpose - activated via “Function” programmed logics
