Menu for the input to function as per the manufacturers specifications and be in accordance with the
relevant Standard.

As can be seen from above the;
1.
Gas Fired Output can be wired to any interfacing or 1A monitoring circuit that requires a closed
relay contact to indicate a change of state. This could be a relay or a solid state device.
2.
System Inoperative Outputs 27V @ 1A to supply interfacing, signage and aural alarms to
indicate the system has been taken out of service or has developed a fault.
