GJD023 12v PIR External White
A robust external 35 metre passive infra red intruder detector designed to give reliable event-based triggers that simultaneously or individually control cameras, VCR’s, DVR’s and all low voltage switching requirements. ADAPTABILITY The Elite offers a high level of programmability, there are seven different modes of operation giving various permutations of normally open and normally closed arrangements for the two pairs of volt-free relays, plus a selection of timing and functional options for the relay changeover contacts. Other programmable parameters include the duration of timed changeover, a pulse count feature and a choice of detection ranges from 10 to 35 metres. In addition there are two switched negative outputs. The 'A' output gives a single 400ms trigger every time the detector activates and is generally used in conjunction with the GJD lighting controllers to give 24-hour visual and audible alarm indication. The 'S' output is the only photocell-controlled output giving a fixed 60-second trigger on activation. The flexibility of the four outputs and timers allows the Elite to be used in multiple situations without the need for any further customised equipment. The integral dual axis tilt sensor allows 180º of pan and 90º tilt. This increases the speed of the outdoor installation and provides incredibly accurate aiming of the detection pattern. The electronics module is acrylic coated for additional component stability. It is encased in a vandal-resistant high impact ABS housing with a UV stabilised translucent front cover ensuring the sensor is impervious to and unaffected by weather conditions. The Elite's effective design gives a neat appearance with no visible indication of the orientation of the detector head, and totally hides the wiring. RELIABILITY Detecting emitted infrared energy of humans equates to recognising subtle changes of energy in the detectors field of view whilst rejecting changes in other wave lengths that are caused by other factors. The Elite's custom designed ASIC microprocessor combined with our unique optical system, filters the information received to give the required precision detection performance. GJD combine this technology with a double silicon shielding of the pyroelectric sensor. The combination of precision electronics, digital white light filter and double shielding resists more than 50,000 lux of unwanted sunlight, therefore eliminating false alarms from visible light sources.
