تماشای ویدئو Line type heat detector SecuriSens ADW 535 from Securiton از آی-ویدئو

The SecuriSens ADW 535 uses a physical principle to its advantage: If the ambient temperature increases in the event of fire, the volume of heated air also expands. Air-filled sensing tubes transmit this pressure increase to a sensor in the cable terminal processor. The system triggers an alarm as soon as a defined limit is exceeded. Two sensing tubes (Double Tube) can be connected to the SecuriSens ADW 535. This means that the monitoring area is doubled and the system can be optimally adjusted according to
