Detecting fires under extreme conditions

The line-type heat detector ADW 535 is applied in areas where a standard fire detector has its limits. Under extreme conditions like humidity, steam, heat (up to 800°C) etc. the ADW 535 detects faster than regular heating cables because of its two sensor tubes (Double Tube Technology).

A pressure sensor measures the air pressure of the sensor tubes permanently and analyses the data by differential analysis and maximum analysis. The ADW 535 can be programmed individually to its ambient conditions. For variable requirements the tubes of the ADW 535 are available in copper, stainless steel or teflon. The unique Dynamic Heat Watch Technology prevents unwanted alarms caused by fast increase in temperature.
