Maintenance and Service
In Germany, maintenance work and inspection work on security systems are governed by the
regulations of DIN VDE 0833; these regulations stipulate reference to the manufacturer’s
instructions for maintenance intervals.
–
Maintenance and inspection work should be carried out regularly and by trained
personnel.
–
BOSCH ST recommends carrying out a functional and visual inspection at least once a
year.

FAP-OTC 420 / FAP-DOTC420
An FAP-OTC 420 will deactivate its C sensor after 6 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.
