Field relay Requirements:
Coil resistance – 2k6 to 4k5 Ohms
Voltage 24VDC Nom
[min 18V, max 30V]
Fitted with suppression diode as shown.

Fire and Fault output
wiring shown for the
monitored/powered
configuration
For Fire and Fire Protection O/Ps:
Quiescent: 2VDC [open circuit voltage]
Active [fire]: 24V – [nom]
For Fault O/P:
Quiescent: 24VDC [nom]
Active [fault]: 2VDC [open circuit voltage]
Connections:
Observe correct polarity.
[+ = Positive, - = Negative]
Fire Routing, Fault Routing and Fire Protection O/P configuration - Output specification:
When configured as monitored/powered outputs:
For Fire and Fire Protection O/Ps:
Volt free relay contacts shown in quiescent [de-energised]
condition.
For Fault O/P:
Volt free relay contacts shown in healthy [energised]
condition.
Connections:
Connect to normally open or normally closed contact as
required. [P= Pole, C= Closed, O= Open]
Applied voltage must not exceed 30VDC.
When configured as volt-free changeover relays:
Terminal identification notes:
C/C = Class Change.
