ELKRON FIRE 80SD5700121 FDT500 Low profile digital heat detector. complete with self-learning circuit

FDT500 Low profile digital heat detector. complete with self-learning circuit. EN54 part 5-17 certification No. 1293-CPD-0342

Low profile heat detector, complete with self-learning circuit and short circuit isolator. Heat detectors monitor the temperature within the area in which they are installed. A microcontroller analyzes and compares the signal it receives from a precision NTC-type temperature sensor, activating the alarm if the temperature exceeds 58°C. Power supply voltage: 20Vcc (modulated voltage from -15% to + 10%) Average absorption at rest: 250 uA@20Vcc Absorption in alarm: 2mA@20Vcc Static alarm threshold: 58° Two-colour LED: red alarm - green normal operation Humidity relative max: 93%. Operating temperature: 0 ÷ 50°C Weight: 70 g. Dimensions: ø 90 x 40 (H) mm. EN 54 part 5 class A1S and 17 certificate (1293-CPD-0140)
