What is BS EN 54-27– Duct smoke detectors about?

BS EN 54 is a European Standard on fire detection and fire alarm systems. It aims to establish operationally efficient safety equipment and systems that play a positive role during a fire emergency.

BS EN 54-27 is the 27th part of multi-series that specifies requirements, test methods, and performance criteria for fire detectors that detect smoke in air ducts in buildings as a part of fire detection and fire alarm system or as an actuator for a fire protection system.

Note: Certain types of detectors contain radioactive materials. The national requirements for radiation protection differ from one member state to another and are not specified in this BS EN 54-27.

Who is BS EN 54-27 - Duct smoke detectors for?

BS EN 54-27 on duct smoke detectors is relevant to:

Manufacturers of fire detection and fire alarm devices
Manufacturers of duct smoke detectors
Product design engineers
Fire safety department
Insurers
Entities involved in fire safety engineering
Local authorities

Why should you use BS EN 54-27- Duct smoke detectors?

Duct smoke detectors (DSD) are used as part of a fire detection and fire alarm system or as a stand-alone actuator for a fire protection system to sample the air within air ducts of a building. Detection of smoke can be used as a signal to the connected control and indicating equipment and can be used as a signal to an airhandling system to prevent the spread of smoke within the building.

A DSD is required to function satisfactorily not only in the event of a fire, but also in the conditions likely to be met in practice such as corrosion, vibration, direct impact, indirect shock and electromagnetic interference. Some tests specified are intended to assess the performance of the DSD under such conditions. The performance of DSD is assessed from results obtained in specific tests.

Overall, BS EN 54-27 can demonstrate the reliability and performance of duct smoke detectors, thus playing a positive role in the optimal performance of fire detection and fire alarm systems, for a successful and timely emergency response.
