7.2 Performance check
The selftest automatically subjects the detectors to an extensive electrical
performance check. Regular performance checks of the detectors are required
nonetheless. These can be performed using test gas or hot air.
Recommendation:
●
Perform a visual inspection on all detectors every year. Detectors that are
heavily soiled or mechanically damaged must be replaced.
●
All detectors should be replaced after 6 to 8 years of service, depending on the
ambient conditions.
