BS 7273-4:2015

Code of practice for the operation of fire protection measures. Actuation of release mechanisms for doors

Status : Current   Published : June 2015



What is this standard about?

BS 7273-4 covers the electrical control arrangements for actuation of mechanisms that unlock, release or open doors in the event of fire. 

Who is this standard for?

  • Fire alarm manufacturers and installers
  • Enforcing authorities including building control bodies and fire and rescue 
  • Fire consultants
  • Fire risk assessors

Why should you use this standard? 

It helps to ensure that a building can be safely evacuated where there are fire doors held open or exit doors that need to be released by the fire alarm system. The recommendations also cover how the mechanisms to unlock, release or open doors interface with the fire detection and fire alarm systems. This leads to a better understanding of safety measures and complies with the latest fire safety legislation.

What’s changed since the last update?

This is a full revision of the standard and introduces the following principal changes:

  • Revised diagrams for the siting and spacing of the smoke detectors in relation to electrically held-open fire doors
  • Inclusion of which category of actuation is appropriate for a particular application
  • Simplified recommendations and terminology, with some of the commentary text tabulated and moved to new informative annexes
