Kidde Graviner Oil Mist Detection system Mk7 detectors

The Mk7 detectors still use optical sensing; (light scatter) as it’s detection method and continually monitors the oil mist density in the crank space to which it is connected. In addition, it self checks for any internal faults. The Control Unit interrogates each detector in turn, identifies the position connected at the Control Unit, the oil mist density value and determines the status of the detector.
