Part 4 of BS 7273 provides recommendations for the design, installation, commissioning and maintenance of electrical control arrangements for actuation of door release mechanisms, namely arrangements that:
- release fire doors that are normally held in the open position (e.g. by electromagnets), so permitting them to close automatically under the action of the self-closing device when the fire alarm system operates;
- unlock doors on escape routes that are normally electronically locked (e.g. by a solenoid or magnetic lock); or
- cause powered, sliding doors on escape routes to become permanently open.
The scope of BS 7273-4 includes acoustically actuated and radio-actuated door release arrangements. Advantages and disadvantages of both methods of actuation are described in annexes.
