Description of BS 5446-4:2020 2020

This part of BS 5446 specifies requirements and type test methods for multi-sensor fire alarms, using one of the following combinations of sensors:

  1. smoke and heat;

  2. smoke and carbon monoxide;

  3. carbon monoxide and heat; and

  4. smoke, carbon monoxide and heat.

It is applicable to multi-sensor fire alarms intended solely for permanent installation on ceilings or walls of dwellings, and to multi-sensor fire alarms suitable for use in leisure accommodation vehicles (LAVs).

It is not applicable to multi-sensor fire alarms incorporating ionization smoke sensors.

NOTE 1 Equipment conforming to this part of BS 5446 might not be suitable for use in boats used as a means of accommodation on inland waterways, due to the corrosive atmosphere.

NOTE 2 Although not covered by this part of BS 5446, equipment is available for use with multi-sensor fire alarms to provide a suitable warning system for use by deaf and hard of hearing people (see BS 5446‑3).

NOTE 3 This part of BS 5446 does not cover the requirements for devices intended for incorporation in fire detection and alarm systems (see BS EN 54‑1).

NOTE 4 This part of BS 5446 does not include detection of carbon monoxide as a toxic gas (see BS EN 50291‑1).

NOTE 5 This part of BS 5446 does not include detection of fire using heat only (see BS 5446‑2).
