Vimpex ELS2A4AO Loop Sounder with Shallow Base in White

Vimpex ELS2A4AO Loop Sounder with Shallow Base in White

Vimpex ELS2A4AO Loop Sounder with Shallow Base in WhiteInstalling 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 5839-12002A22008 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.

Aritech EV1116 16m PIR Volumetric Detector With 11 Curtains Grade 2

Aritech EV1116 16m PIR Volumetric Detector With 11 Curtains Grade 2

Aritech EV1116 16m PIR Volumetric Detector With 11 Curtains Grade 2Aritech motion sensors have the most advanced and sophisticated optics in the security industry. This unique optical mirror technology is a step and gliding focus which creates a continuous curtain resulting in a sensor that never loses track of the object.To increase detection coverage the EV1100 series sensors incorporate a 3-step gliding focus which produces 11 continuous curtains to detect infrared signals up to a 16 m distance.5D signal processing5D is the next generation of Aritech signal processing. It builds on the current strengths of 4D but adds an intelligent differentiation between fast and slow moving signals.When a slow thermal source is detected the signal processing switches automatically to the 5D mode and executes additional pattern recognition to distinct this signal from a slow walking person. If the signal fits it must be an intruder and an alarm is generated. If there is no fit the signal is ignored which ensures signals such as moving reflection of sunlight are filtered out.The result is a unique combination of high sensitivity detection with high false alarm immunity without the need for manual sensitivity adjustment.Key FeaturesPassive Infra Red motion sensor3Brid Step Gliding Focus Curtain mirrorPlug-in electronicsSealed optics5D signal processing for false alarm immunityCloak and umbrella immunityFull under crawl detectionSelectable coverage pattern using mirror masksAuto focus with constant range sensitivityNo adjustment required for different mounting heightsTolerates wall angle deviationCertified EN50131-2-2 Grade 2Several European approvals
