BS5839-1:2017 Section 6, 44.2

Recommendations for weekly testing by the user


NOTE 1:   When testing the fire detection and fire alarm system, there might be a need to disable ancillary outputs.


The following recommendations are applicable.

  • a) Every week, a manual call point should be operated during normal working hours. It should be confirmed that the control equipment is capable of processing a fire alarm signal and providing an output to fire alarm sounders, and to ensure that the fire alarm signal is correctly received at any ARC to which fire alarm signals are transmitted. It is not necessary to confirm that all fire alarm sounder circuits operate correctly at the time of this test.


NOTE 2:   It is essential that any ARC is contacted immediately before, and immediately after, the weekly test to ensure that unwanted alarms are avoided and that fire alarm signals are correctly received at the ARC.


NOTE 3:   The user needs to take account of the manufacturer’s recommendations, particularly when battery powered devices are being tested, e.g. within radio-linked fire detection and fire alarm systems.

  • b) The weekly test should be carried out at approximately the same time each week, occupants should then be instructed that they should report any instance of poor audibility of the fire alarmsignal. In systems with staged alarms incorporating an “Alert” and an “Evacuate” signal, the two signals should be operated, where practicable, sequentially in the order they would occur at the time of a fire (i.e. “Alert” and then “Evacuate”).

  • c) In premises in which some employees only work during hours other than that at which the fire detection and fire alarm system is normally tested, an additional test(s) should be carried out at least once a month to ensure familiarity of these employees with the fire alarm signal

  • d) A different manual call point should be used at the time of every weekly test, so that all manual call points in the building are tested in rotation over a prolonged period. There is no maximum limit for this period (e.g. in a system with 150 manual call points, the user will test each manual call point every 150 weeks). The result of the weekly test and the identity of the manual call point used should be recorded in the system logbook [see 40.2d)].

  • e) The duration for which any fire alarm signal is given (other than solely at CIE) at the time of the weekly test by the user should be at least 5s, but should not normally exceed 60 s, so that, in the event of a fire at the time of the weekly test, occupants are warned by the prolonged operation of the fire alarm devices.

  • f) Voice alarm systems should be tested weekly in accordance with BS 5839-8.
