Guidance – Fire Detection and Alarm Maintenance

BS 5839, part 1 2013 provides recommendations for the planning, design, installation, commissioning and maintenance of fire detection and fire alarm systems in and around buildings, other than domestic premises.

Routine testing by the user

Weekly

1. Test a manual call point during normal working hours to confirm that the control panel and sounders operate satisfactory. The weekly test should be carried out at approximately the same time each week and occupants should be asked to report any instance of poor audibility. In premises where employees only work hours outside when the fire detection and alarm is tested, then additional test(s) should be carried out at least once a month.

2. Each week a different manual call point should be tested, so that all points in the building are tested over a prolonged period. The result of the weekly test and identification of the manual call point operated should be recorded in a log book.

3. The duration of the fire alarm activation should not normally exceed one minute so that occupants can determine the difference between a weekly test and real fire.

4. Voice alarms should be tested weekly in line with BS 5839 part 8.

Monthly

1. Any automatically started emergency generator should be tested by simulation of power failure and operated on-load for at least one hour in line with any manufacturer’s instructions.

2. Any vented batteries used as a standby power supply should have a visual inspection. Action should be taken to rectify and defect, including low electrolyte level.

Inspection and Servicing by a competent person

Periodic inspection and servicing needs to be carried out by a competent person, with specialist knowledge of fire detection and fire alarm systems. This will normally be done by an outside fire alarm servicing organisation. Competence can be assured by the use of an organisation that is third party certificated by a UKAS accredited body, to carry out inspection and servicing of fire alarms.

The period between successive inspection and servicing visits should be based upon risk assessment. The recommended period between visits should not exceed 6 months.

BS 5839, part 1 2013, section 6 provides a comprehensive list of recommendations for periodic inspection and testing of the fire detection and alarm system.
