The smoke detector is intended for detecting fire in its early phase. The detector has an optic, scattering smoke sensor. The application of such type of a sensor allows to detect fire quick and with certainty. Additionally, the detector has the flashing visual signalling device built-in due to which the detector fire alarm is visible from a large distance. The detector operates within the AWEX fire alarm system. The element can be installed on the detection loops or stub detection circuits.
The smoke detection takes place in a detection chamber equipped with photoelectric diodes. Smoke goes to the chamber during fire. The particles of smoke reflect the light emitted by light emitting diodes which causes that an IR diode receives the signal and transmits it to a microprocessor. Then, it recognises the type of alarm and transmits it to the supervisory line, and to the control unit.
