The DH400AC/DC-E duct detector can be used either as part of a fire detection system with a control panel or as a stand-alone duct smoke detector which can be used to activate a sounder and shutdown fans, blowers or airconditioning systems, so preventing the spread of toxic smoke and fire gases through the protected area. The wist-in, twist-out heads allow for quick and easy cleaning or application changes without removing the duct housing. Since duct detectors are often mounted in inaccessible areas, the RTS-451 remote test station can be mounted at a convenient location and allows the detector head to be tested without the need for access to the duct detector. Sampling tubes are available separately in four different lengths to suit ducts from 0.3m to 3.6m wide.
