Beam báo cháy Siemens FDL241-9

Thông tin chi tiết

FUNCTION
– The detector consists of a light emitter and a light receiver. The light emitter emits a bundled infrared ray, which is scattered back by the prism-shaped reflector to the light emitter. The receiver converts the received infrared signal in an electric signal, which is evaluated by the microprocessor-controlled electronics.
– Smoke penetrating the measuring section attenuates the infrared signal. When the signal reaches predefined measuring values, the detector transmits the corresponding danger level to the control unit.
– Distance measurement for the recognition of foreign matters.
– The built-in response indicator signals the alarm status locally.
