Please complete the form below. 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 restricted movement.
Text has been shortened and simplified to make the standard more straightforward to use. Standard Number BS WHEN a fire breaks out in a building, every second counts when it comes to people getting out safely.
There can be no one size fits all approach to configuring a BS compliant system and fire doors and exits should be considered individually so that people, property and assets are protected as well as they possibly can be in the event of a fire. Take the smart route to manage medical device compliance. This is intended to make the recommendations clearer and to remove possible confusion where a single diagram has been used to convey several principles applying to detector siting and spacing There have been changes in terminology to assist users of the standard.

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. Please download Chrome or Firefox or view our browser tips.
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.

This will encourage a uniform approach by enforcing authorities and others in specifying objectives that ensure that people, property and assets are protected as well as they possibly can be in the event of a fire. It addresses safety critical arrangements that enforcing authorities rely on to ensure a building can be evacuated safely – where fire doors are held open or exits secured which need to be released by the fire alarm system.

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.

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. 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.
This standard relates to the engineering of fire alarm systems and in particular mechanisms to interface with fire doors and secured fire exits.

Previously, a device local to the doors effectively switched the doors to fail safe mode and released electrically secured fire exits and closed fire doors held open on magnetic door retainers.
Overview Product Details What is this standard about? Body Although it was first introduced inthe revision of BS has brought the subject of release mechanisms for fire doors into sharp focus. Designers must ensure that the controller itself is also failsafe. If be guidelines are not followed it is likely that the fire door provision fails to satisfy the fire risk assessment.
BS covers the electrical control arrangements for actuation of mechanisms that unlock, release or open doors in the event of fire. As one door opens Category B and C applications should both fail safe when the Critical Signal Path is interrupted by a short or open circuit. Title Gs one door opens This is a full revision of the standard and introduces the following principal changes: The update of BS addresses some of the reasons for its lack of uptake clarifying the classification of the category of installation as well as when they should be used.
Imagine not having the security of knowing that a fire was contained because the doors had not gone into fail safe mode.
One of the key reasons behind the standard was to ensure that door management systems for doors critical to the safe management of a building in a fire situation must be fail safe such that the protection of the building is not impacted if for any reason the automatic control is compromised.
Category A – the most stringent – is to be applied for the highest risk situations, requiring fail safe operation when the cabling forming the communication path is broken, and when there are faults or disconnections that prevent the operation of the mechanism in a fire. Some of the commentary has been moved to new informative annexes and some of the previous text has been tabulated The diagrams relating to the location of smoke detectors in relation to electrically held-open fire doors have been revised.
