Installing a Vimpex Loop Sounder System with short-circuit isolation provides complete sounder circuit integrity. By wiring the sounder circuit in a loop instead of a traditional radial, all sounders will remain operational in the event of a short-circuit or open circuit fault.
The system and its components have been tested by leading European notified bodies and have been shown to comply with EN 54-3, EN 54-17 and EN 54-18. The system is fully compliant with BS 5839-1 using a single sounder loop. Use of the Vimpex Loop Sounder System will greatly increase the reliability of the sounder circuits and in many cases result in a saving in the amount of cable used. Each loop can accommodate up to 45 sounders. Suitable for use on both conventional and addressable fire alarm systems, the system provides much greater protection against faults than the ‘dual radial’ circuit arrangements commonly used.
The Vimpex Loop Sounder System has been fully tested and approved by LPCB and Intertek to relevant EN 54 standards - certificates are available on request. This system is detailed in BS 5839-1:2002+A2:2008 (clause 12.2.2 j and Fig 1b) as an alternative to the use of dual radial circuits. A detailed application guide is available from Vimpex as is a system loop calculator.
