AL.

: The contact is activated due to the
gas alarm.

FAU.

: The contact is activated due to the
fault alarm.

A. or F.

: The contact is activated due to the
gas alarm or the fault alarm.

WARNING



When the detector is turned off, an alarm may be triggered on the upper (central) system.



Before turning off the detector, INHIBIT (point skip) on the upper (central) system must be
activated. Decide whether the power can be turned off by checking the operation of the
devices connected to the external output or external contact output terminal of the detector.



If the alarm contact is energized (option), it is activated when the detector is turned "OFF".
