Edwards Signaling SD4WJ


  • Also known as: ED-SD4WJ

    • The EDWARDS-SIGNALING-SD4WJ is a 4-wire duct smoke detector with photoeletric type that features environmental compensation with differential sensing, which enables the unit to be immune from sensitivity drift a common cause of false alarms.

    Every eight minutes the SD4WJ checks its environment for dirt, humidity other conditions that normally interfere with sensor operation, and automatically adjusts its sensitivity to compensate. The unit can be tested for dirt contamination remotely, eliminating the need to physically access the detector with a sensitivity tester.

    The SD4WJ's snap-in RJ45 connectors reduce time spent on controller/detector interconnection to just a few seconds, while sampling tube spacing - and even field wiring connections - match standard configurations.    		Features:
    • Less than 2" deep for easy installation and applications where space is tight
    • PCB mounted photoelectric sensor with on-board inteliigence
    • Environmental compensation with patented differential sensing
    • Standard RJ45 interconnection
    • Status LEDs remain visible even after installation
    • Cover tamper reed switch
    • Sampling tubes install from room-side or air-side
    • Magnet-activated test/dirty switch
