ADW

 

How It Works

The Transafe ADW thermal fire detector analyses the physical change in volume of gases and temperature fluctuations in the systems copper sensor tube.

 

A fully electronic pressure transducer calculates the absolute pressure in the sensor tube. By adjusting the on-board sensors the response behaviour of the detector can be adjusted precisely to the detection requirements.

 

A test motor with a pressure pump generates an intentional, exactly defined excess pressure in the sensor tube at regular intervals.

 

If the measured value of the pressure sensor does not correspond to the required value, for example due to a leak or compression of the tube, a fault indication occurs.
