Vimpex Loop Controller Module - Single Loop - DINT1

The Vimpex Loop Sounder System is based around the DINT Loop Controller Module, which is interfaced with a standard sounder circuit. Sounders are activated and monitored just like any other conventional sounder circuit. The small module is designed for DIN rail mounting within the PS18181-11m wall-mounted enclosure which is available from Vimpex. 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 shortcircuit 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.
