Edwards Signaling SD-4WPCBT

Reliability and stability are two features built into every SuperDuct detector. SuperDuct features environmental compensation with patented differential sensing. This achieves a level of stability and reliability never before achieved for devices of this type. With differential sensing, SuperDuct sensors are immune from sensitivity drift – a common cause of false alarms. Every eight minutes the SuperDuct sensor checks its environment for dirt, humidity other conditions that normally interfere with sensor operation, and automatically adjusts its sensitivity to compensate. The result is unparalleled reliability and rock solid stability – two features essential to any duct smoke detection application.
