LED smoke detector WM 4000

Together with the RZ-24 central unit Characteristics Heat differential detector tested in accordance with EN 54-5 Responds not only when a certain temperature has been reached, but also when the temperature increases rapidly Should be used whenever there’s a danger of false alarm from smoke detectors caused by smoke or similar airborne particles (e.g. dust) that may occur during normal working conditions (ATTENTION: observe national regulations in your country!!!) Standard temperature level between 54 °C and 65°C. Heat detectors with different levels of demand are also available on demand Operated together with the RZ-24 central unit which supplies the necessary voltage to the detector and simultaneously evaluates it. This reduces the cost of the system considerably. Single operating states are indicated via integrated LED with 360º visibility in two colors (red/yellow) and different flashing frequencies Product information Supply voltage8.5 to 33 VDC Power consumptionØ quiescent current + switch-on surge current at 24 VDC: 95 μA Alarm current at 24 VDC: 40 mA Heat measurementby means of a thermistor, 1 measurement every 4 seconds Operating temperatureA1R: static response temperature between 54 °C and 65 °C; operating temperature: -40 °C to +50 °C (without alarm) Alarm indicatorintegral LED for status indication IP ratingIP 23D Material casingmoulded in white polycarbonate
