Regin brand detectors of the SDD series are suitable for placement in ducts, pipes and ventilation systems . They meet all the requirements of a fire alarm installation . They have an alarm for early warning of smoke. Detectors with relays are not connected to the control panel, but allow the detector to trigger an alarm independently without being connected to the control unit.

Ionization type detectors respond to visible and invisible smoke particles . They operate on the principle of two chambers, one of which is closed and serves as a reference and the other is open and receives particles from the surrounding air. When smoke particles enter the open chamber, the values change compared to the reference chamber and an alarm is triggered. Ionization detectors are suitable for fast burning fires.
