SMOKE DETECTOR WITH THE VISUAL SIGNALING DEVICE SF

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.

Characteristics of the smoke detector:

  • The level of sensitivity comply with the EN 54 standard
  • Recognition of the state of soiling
  • Regulation of alarm threshold which compensates the influence of the environment
  • Indication of an alarm by means of the LED diode
  • Additional LED diodes for the testing state
  • External status indicator
  • Integrated short-circuit isolator
  • A casing with a low profile
  • Operation in the addressable systems
