This standard relates to the engineering of fire alarm systems and in particular mechanisms to interface with fire doors and secured fire exits. Find Similar Items This product falls into the following categories. Text has been shortened and simplified to the standard more straightforward to use.
BS Although it was first introduced inthe revision of BS has brought the subject of release mechanisms for fire doors into sharp focus. 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.
Skip to main content. 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. BS operation of fire protection measures Category B and C applications should both fail safe bbs the Critical Signal Path is interrupted by a short or open circuit.
Please complete the form below. It is vital that there is a common approach to fire alarm design with regard to these interfaces. Control of doors within a building by the fire detection system has been commonplace for many years.
You may experience issues this site in Internet Explorer 9, 10 or Although it was first introduced inthe revision of BS has brought the subject of release mechanisms for fire doors into sharp focus. Search form Search Means of Escape. One of the key reasons behind the standard to ensure that door management systems for doors critical to the safe management of a building in a situation must be fail safe such that the protection of the building is not impacted if for any reason the automatic control is compromised.
This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Those attending will also gain an valuable understanding of the three categories of actuation — A criticalB standard and C indirect — and be 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. Category applications require additional consideration as bss apply when the fire system connects to the release system indirectly, for example via an access control system.
Actuation of release mechanisms for doors Status: Overview Product Details What is this standard about? Imagine not having the security of knowing that a fire was contained because the doors had not gone into fail safe mode.
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 stands to reason that the prompt evacuation of a burning building requires as few obstacles and obstructions as possible.
Designers must ensure that the controller itself is also failsafe. 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.
This is a full revision of the standard and introduces the following principal changes: 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.
As such BS It covers recommendations for the interface between fire detection and alarm systems, as well as equipment not covered in any other standards. Standard Number BS Relevant opportunites Please tick if you do not wish to be contacted regarding relevant opportunities. Simon Foulkes, Product Owner at Gent by Honeywell, examines this revised code of practice and explains why more attention should be given to this important subject.
This question is for testing whether you are a human visitor and to prevent automated spam submissions. This question is for testing whether you are human visitor and to prevent automated spam submissions. 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.
This is a full revision of the ba and introduces the following principal changes:. Balance this with the need to conveniently use the building in normal operation and you can potentially have conflicting priorities. Body Although it was first introduced inthe revision of BS has brought the subject of release mechanisms for fire doors into sharp focus. Who is this standard for? The recommendations also cover how the mechanisms to unlock, release or doors interface with the fire detection and fire alarm systems.
If the guidelines are not followed it is likely that the fire door provision fails to satisfy the fire risk assessment.
BSI Revises BS 7273-4:2015 Code Of Practice For Fire Protection
Download PDF version The standard relates to the engineering of fire alarm systems, fire doors and secured fire exits BSI , the business standards company has revised BS Code of Practice for the operation of fire protection measures - Part 4: Actuation of release mechanisms for doors. Fire doors are typically designed to be kept closed at all times so that fire and heat are contained and their spread minimised. This is achieved through use of well-engineered fire doors. This standard relates to the engineering of fire alarm systems and in particular mechanisms to interface with fire doors and secured fire exits. 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.
What you need to know about BS 7273-4:2015
BS Code of practice for the operation of fire protection measures — part 4: Actuation of release mechanisms for doors was published on 30 June It replaces the version, which is superseded, and although the version is heading towards three years old, it is all too easy to forget which parts were updated. So, for those of you who need a refresh, read on… BS in a nutshell is about the operation and release of fire doors. It recommends how to actuate mechanisms that unlock, release or open doors in the event of fire in all buildings including dwellings except where stated. It provides recommendations for the design, installation, commissioning and 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 also enhances some of the recommendations of BS with regard to detector siting and spacing in certain categories of system.
