FAP-OTC 420 / FAP-DOTC420
An FAP-OTC 420 will deactivate its C sensor after 5 years of operation due to the gas
sensor's limited life cycle.
On the panel, the detector in question is displayed with "EMERGENCY OPERATION" and
it continues to function as an OT or O detector.
With the FAP-DOTC420, the gas sensor has a life cycle of 6 years. Once the gas sensor
has been switched off, this detector continues to function as a DOT or DO detector and
is displayed on the panel with "EMERGENCY OPERATION".
This is why multisensor detectors with C sensors need to be exchanged every 5-6
years.
Optical fire detectors should, depending on the environmental conditions, be cleaned
and exchanged regularly.
In especially dusty environments, cleaning and exchange may be necessary earlier.
Every detector base has a Chamber Maid Plug
(cleaning opening with a plug) for blowing out
the optical chamber with compressed air (not
required for the FAH-T 420 Heat Detector).
