EN54 FIREFINDER PLUS INSTALLATION,COMMISSIONING & OPERATION
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 FARE 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 FWRE disable condition.
 Isolate - activated on all isolate conditions and “Function” programmed logics.
 Battery Fail - activated on battery fail conditions and “Function” programmed logics.
 EWIS - 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.
 AUX / ANC - activated on device alarm conditions.
 General Purpose - activated via “Function” programmed logics
These outputs have been designed to be able to switch predominately resistive loads as listed
below.
