BS EN 54 is a European Standard on fire detection and fire alarm systems. The main objective of the BS EN 54 series is to establish efficient safety and protection systems that play a positive role during a fire emergency. BS EN 54-7 is the seventh part of the series that specifies requirements, test methods, and performance criteria for point smoke detectors that operate using scattered light, transmitted light, or ionization, intended for use in fire detection and fire alarm systems installed in and around buildings. For other types of smoke detectors, or smoke detectors working on different principles, this BS EN 54-7 should only be used for guidance. Note: Smoke detectors with special characteristics and developed for specific risks are not covered by this BS EN 54-7. Who is BS EN 54-7- Point smoke detectors for? BS EN 54-7 on point smoke detectors is relevant to: Manufacturers of fire detection and fire alarm systems Manufacturers of smoke detectors Product design engineers Installers Entities involved in fire safety engineering Fire safety departments Local authorities Why should you use BS EN 54-7 - Smoke detectors? A smoke detector is a device that senses smoke and will sound an alarm whenever there's a threat of fire on your property. BS EN 54-7 covers best industry guidance and requirements for compliance, operational reliability, response time, activation conditions/sensitivity, tolerance to supply voltage, performance parameters under fire conditions, amongst others. If you are a manufacturer, testing and compliance with BS EN 54-7 is beneficial to determine the performance and durability of your products. You can evaluate whether the smoke detectors are resistant to the corrosive effects of sulfur dioxide as an atmospheric pollutant. Moreover, properties such as resistance to temperature, humidity, vibration and electric stability can also be evaluated. As a result, you can identify failure of alarm and fault signals and minimize incidents of delayed and false alarms. By establishing performance and conformity of point smoke detectors using scattered light, transmitted light or ionization with BS EN 54-7, you can demonstrate reliability for your products. What’s changed since the last update? BS EN 54-7:2018 supersedes BS EN 54-7:2001, which is withdrawn. BS EN 54-7:2018 includes the following new clauses and annexes: Clause 6, Assessment, and verification of constancy of performance (AVCP) Clause 7, Classification Clause 8, Marking, labelling, and packaging Annex N (normative), Test set up for testing the protection against the effect of moving objects Annex O (normative), Apparatus open detector static object test Annex P (informative), Data supplied with point smoke detectors
