What is BS EN 54-22 about?
BS EN 54-22 is the twenty-second part of a multi-series applies to resettable line-type heat detectors consisting of a sensing element using an optical fibre, a pneumatic tube, or an electrical sensor cable connected to a sensor control unit, either directly or through an interface module, intended for use in fire detection and fire alarm systems installed in and around buildings and other civil engineering works.
BS EN 54-22 specifies the requirements and performance criteria, the corresponding test methods and provides for the Assessment and Verification of Constancy of Performance (AVCP) of resettable line-type heat detectors to this EN.
BS EN 54-22 also covers resettable line-type heat detectors intended for use in the local protection of plant and equipment.
Who is BS EN 54-22 for?
BS EN 54-22 on alarm systems. intrusion and hold-up systems applied for the following:
- Manufacturers and service providers of fire alarm system
- Emergency response team
- Security management system of a building
- Installers and Maintainers of resettable line-type heat detectors
- Manufacturers of resettable line-type heat detectors
Why should you use BS EN 54-22?
Resettable line-type heat detectors (RLTHD) have been incorporated into fire alarm systems for a considerable number of years. These detectors are typically used in areas where point type heat detectors are presented with challenging environmental characteristics and also where access to the detectors may significantly influence the fire alarm system design.
BS EN 54-22 defines the minimum system functionality for RLTHD products. RLTHD are based upon many unique operating principles. BS EN 54-22 helps you with the common operating characteristics for each type of RLTHD in conjunction with existing EN 54 detector standards, so that resettable line-type heat detectors have a response behaviour comparable to that of point type heat detectors.
Due to the various applications for RLTHD, it is necessary to devise separate environmental classification tests for the sensing element and the sensor control units of these systems.
For this purpose, BS EN 54-22 indicates two general fields of application, room protection and secondly local protection. The standard defines separate response test classifications for these two fields.
BS EN 54-22 is useful because it can enable you to get an early signal of something that could be tragic basically saving your lives. A fire alarm alerts you when you are busy, working, or sleeping.
