Basic Operation

WARNING
•
When the detector is turned off, an alarm may be activated on the upper (central) system.
Before turning off the detector, the 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), they will activate when the detector is turned "OFF".
•
If the detected gas is absorptive, the detector must be flushed thoroughly with fresh air before turning
"OFF" the detector.
