5-8. How to exit
To turn off the gas detector, turn "OFF" the power switch located on the rear side of the main unit. Then, turn
off the power supply to the gas detector.
WARNING

When the gas detector is turned off, an alarm may be triggered on the upper (central) system.
Before turning off the gas 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 gas detector.

If the alarm contact is energized (option), it is activated when the gas detector is turned "OFF".

If the gas to be detected has an adsorptive property, the gas detector must be cleaned thoroughly
with fresh air before turning "OFF" the gas detector.
