Maintaining your fire alarm system
Regular servicing and maintenance is an important part of limiting the false alarms that may occur on a system. BS 5839-1 gives recommendations for periodic inspection and test of the system in Section 6.
Tests for detectors (all types) should ensure that products of combustion are capable of passing into the sensing chamber of the detector and this testing should be carried out by a competent person.
The period between successive inspection and servicing visits should be based upon a risk assessment, taking into account the type of system installed, the environment in which it operates and other factors that may affect the long term operation of the system.
