ASA Linear smoke detector unit
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 to 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 matter. The built-in alarm indicator signals the alarm
status locally. For various distances‚ different reflectors are available.
The optics can be efficiently adjusted to the reflector by single-handed
alignment via the adjustment device FDLU291.
The base FDLB291 must be ordered separately.
