LS82101, Loop Deep Base Sounder and Beacon - Red Sounder/LED

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.

Component parts are approved by LPCB to relevant parts of EN 54 and 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 significantly enhances the reliability of any sounder system. With conventional radial circuits a single open or short circuit fault on a sounder circuit could result in the loss of at least half of the sounders in an area of a building.

The Vimpex Loop Sounder System has been fully tested and approved by LPCB 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.

Each sounder is supplied with a bi-directional short-circuit isolator fitted within its base. In the event of a short circuit the isolators will activate and disconnect the faulty section of cable while reporting (in monitoring mode) the fault to the control panel. When the sounders are activated, the loop is driven from both ends ensuring that all sounders will remain operational even in the event of a single short-circuit or open-circuit fault. Sounders and their isolator bases are installed just like any other conventional sounders on the twin core circuit.
