ELKRON FIRE 80SD1V00121 FDTD400 Low Profile Rate of Rise Heat Detector

FDTD400 Low profile rate-of-rise detector. EN54 part 5 certification No. 1293-CPD-0348

Velocimetric heat detectors monitor the temperature increase 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 increase exceeds 5°C per minute. Power supply voltage: 20Vdc (voltage modulated from -15% to +10%) Average absorption at rest: 40 mA@20Vdc Absorption in alarm: 23 mA@20Vdc Static alarm threshold: 58° C +/- 5% LED at 3 colours: red alarm - green normal operation - green flashing with yellow flashing sequence fault state Max relative humidity: 93% Operating temperature -10° ÷ 55°C Material ABS VO Weight 70 g Dimensions: ø 90 x 40 (H) mm EN54 part 5 class A1R certified, certification number: 1293-CDP-0180
