Guidance on the installation of fire detection and alarm systems is given in Approved document B.

The latest version of Approved document Part B does not give minimum distance from a light fitting, it only states that; Fire detection and alarm systems must be properly designed, installed and maintained.

A design, installation and commissioning certificate should be provided for fire detection and alarm systems.

Usually, the manufacturer’s instructions are consulted for minimum distance from walls and light fittings.
