The GAQ series are Air Quality Sensors and Controllers that automatically react to air pollution sources.
They sense tobacco smoke, toilet odors, strong kitchen smells, etc. and mechanically regulate ventilated areas such as cinemas, pubs, restaurants, toilets or conference rooms.
The sensor switches the fan on when air quality drops below a preset, adjustable level.
The sensing head of the unit is self - cleaning, a process which occurs each time the unit is triggered.
When atmosphere has returned to normal, the fan switches off.
The air quality sensor should not be used for the detection of combustible gases and is not designed for use as a smoke detector in an alarm system!
