Edwards Signaling SD-CJ SuperDuct Series Controller, RJ45, 24V DC/AC, 120/230VAC Operating Voltage, 18VDC Auxiliary Output, Normally Open

Optimize duct smoke detection and building monitoring with the Edwards Signaling SD-CJ SuperDuct Series Controller. This detector accessory delivers reliable, professional-grade performance in confined spaces thanks to a slim profile under 2 inches that simplifies mounting inside ducts, plenums, or compact control enclosures. The PCB-mounted photoelectric sensor uses on-board intelligence and patented differential sensing to reduce false alarms and compensate for changing environmental conditions common in HVAC systems. With wide voltage support (24V DC/AC plus 120/230VAC) and an 18V DC auxiliary output, the SD-CJ integrates seamlessly into fire, security, and surveillance installations, allowing you to power and network ancillary devices via the RJ45 interface. Its normally open configuration and robust sensing make it ideal for commercial and institutional applications where dependable monitoring and quick response are essential. Upgrade your detector accessories and bases with an Edwards Signaling SuperDuct controller to enhance safety, reduce service calls, and simplify system design—perfect for duct detection in hospitals, schools, office buildings and industrial facilities.
