BS 7273-6:2019

Code of practice for the operation of fire protection measures. Fire detection and fire alarm systems. Interface with ancillary systems and equipment | Status: Current, Under review

1 Scope This part of BS 7273 gives recommendations for the design, installation, commissioning and maintenance of interface arrangements between fire detection and fire alarm systems conforming to BS 5839‑1:2017 and various ancillary systems and equipment (ASE), where this interface is required by the fire strategy for a building, excluding the interface with those systems covered in other parts of the BS 7273 series. Arrangements covered by this part of BS 7273 include the interface between fire detection and fire alarm systems and:

• • smoke control systems;
• • lifts and other lifting appliances;
• • gas valves;
• • fire-resisting shutters and active fire curtain barrier assemblies;
• • electricity supplies;
• • ventilation systems;
• • lighting, intelligent signage and wayfinding; and
• • paging systems.

This part of BS 7273 does not apply to the interface between ASE contained solely within a private dwelling and the fire detection and fire alarm system within that dwelling. It applies to systems installed in the common parts of blocks of flats (e.g. activation of the smoke control system), and where the actuation of the detection within a dwelling is intended to interact with a system within common parts (such as in sheltered housing). The scope of this part of BS 7273 is shown diagrammatically in Figure 1.

NOTE 1 Any special recommendations for provision and siting of fire detectors and manual call points are within the scope of this part of BS 7273.

NOTE 2 The effect of failures of power supply for the devices is within the scope of this part of BS 7273.
