6.4 PERIODIC INSPECTION & SERVICING
Inspection & servicing should only be carried out by a ‘Competent Person’ who has sufficient knowledge to
check the whole system. This would normally be a qualified electrical contractor or fire alarm specialist.
Inspection & servicing visits are normally conducted on a quarterly basis unless such factors as a dirty
environment warrant servicing on a more regular basis. The maximum period between inspections must not
exceed six months.
Recommendations of BS5839-1 for periodic service visits include:
• Every device on the system should be tested annually. The testing of each device can be split between
periodic visits but with a minimum of one detector or call point tested on each circuit, per visit.
• On each visit the ‘Competent Person’ should check the record of false alarms. Any persistent occurrence
should be investigated and corrective action taken as appropriate.
• Battery and connections should be examined and load tested to check serviceable condition and that they
are not likely to fail before the next service visit.
• All other devices and control & indicating equipment should be checked for correct operation and any faults
should be recorded and rectified.
• Details of the service visit must be recorded in the log book
