7 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 recommends carrying out a functional and visual inspection at least once a year.

– With the FAP-425-DOTC-R, the chemical sensor has a life cycle of max. 6years. Once the
chemical sensor is 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 FAP-425-DOTC-R detectors need to be exchanged every 5-6 years.
– With the FAP-425-DOTCO-R, the chemical sensor has a life cycle of 10years. Once the life
cycle of the chemical sensor is exceeded, the detector cannot support new sensitivity
settings (for VdS 6017, VdS 6018, VdS 6019) anymore. No emergency operation is
possible as CO sensing is essential for those settings.
This is why FAP-425-DOTCO-R detectors need to be exchanged after 10 years at the
latest.
– 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 has a Chamber Maid Plug
(cleaning opening with a plug) for blowing out
the optical chamber with compressed air (not
required for the Heat Detector).
