Code of practice for the operation of fire protection measures - Actuation of release mechanisms for doors Ingestion-build-67170BS 7273 4: 2007 gives recommendations for: design installation commissioning maintenance of electrical control arrangements for actuation of mechanisms that unlock, release or open doors in the event of fire. It applies to all aspects of the interface between these mechanisms and a fire detection and fire alarm system, including interfaces that incorporate acoustic coupling and radio transmission. It does not recommend whether the above mechanisms
