Temperature Detector DIL SwitchAddressed:
Standard Temperature Detector, DIL style, 55000-465IMC High Temperature Detector, DIL style, 55000-475IMC Our DIL Switch Addressed (DSA) Context Plus temperature detectors have a low air flow resistance case made of self-extinguishing white polycarbonate. The devices monitor temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. The response to heat increases of the standard temperature detector enables the detector to be utilized as an EN54–5:2000 A2S heat detector, which is equivalent to an EN54–5:1984 Grade 2 detector. A high temperature detector, which has similar characteristics at 25°C but reaches a 55 count at 90°C, is available for use in normal ambient temperatures of up to 55°C. This detector meets the requirements for a CS detector in EN54–5:2000. The address of DSA Context Plus temperature detectors is set using the DIL switch located on the underside of the device. All segments are set to 0 (ON) or 1 (OFF), using a small screwdriver or similar tool. The address should be written on the label and the rear of the detector sealed.
The Context Plus XP95 Manual Call Point is intended for indoor applications and incorporates a short circuit isolator which will ensure its operation in the event of a short circuit fault on the loop. The Call Point is surface mountable and has an easily resettable element rather than a break glass. It also features a unique ‘Plug and Play’ installation concept designed specifically to reduce installation time. The call point utilises a terminal block, where all installation cabling is terminated. Its address is set at the commissioning stage by means of a seven-segment DIL switch. A single bi-coloured alarm LED is provided which is controlled independently of the call point by the control panel. The LED is illuminated red when the call point has been activated and amber/yellow to indicate a short circuit. Once activated, the Call Point can be reset by inserting the test key into the bottom of the unit until the key clicks into position, next remove the test key and push the front cover up until it clicks home.
