By providing an overview of the various scenarios when doors should be released, it looks at control arrangements for actuation of mechanisms that unlock, release or open doors in the event of fire, before covering recommendations for the interface between fire detection and alarm systems, as well as equipment not covered in any other standards.

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.

Similarly, restricting the spread of fire and heat in such a situation relies upon the use of well-engineered fire doors that can be reliably closed in the event of a fire.

Those attending will also gain an valuable understanding of the three categories of actuation – A criticalB standard and C indirect – and the circumstances under which the control mechanisms should revert to their fail safe position to protect escape routes and prevent the spread of smoke in the event of a fire. Imagine not having the security of knowing that a fire was contained because the doors had not gone into fail safe mode.

Actuation of release mechanisms for doors. Designers must ensure that the 7723-4 itself is also failsafe. The update of BS addresses some of 7273–4 reasons for its lack of uptake clarifying the classification of the category of installation as well as when they should be used.

Adhering to BS is increasingly important, as the guidance in Annex A of the Code of Practice is now normative, which means that if control of doors is performed by a fire detection system the requirements of the category must be met.

Only a very few of the more intelligent systems can identify whether for instance a fault on a single detector will impact the operation of the door release system.

Category B and C applications should both fail safe when the Critical Signal Path is interrupted by a short or open circuit.

If the listed faults occur in either the door management system, the fire detection system, or the interconnection between the two, the system should perform as it would in the event of a fire and release the doors. Overview Product Details What is this standard about? However, it should be remembered that this type of system might be inappropriate in certain environments such as banks, hospitals and prisons, due to security issues, where doors could be held open to allow access to people who should have bw movement.

Fire doors are typically designed to be kept closed at all times so that fire and heat are contained and their spread minimized. This standard relates to the engineering of fire alarm systems and in particular mechanisms to interface with fire doors and secured fire exits.

It is fair to say that since its original introduction the standard has been largely ignored apart for a few isolated cases of best practice. It helps to ensure that 72734- building gs be safely evacuated where there are fire doors held open or exit doors that need to be released by the fire alarm system.
