System Sensor D4P120 4-Wire Photoelectric Power Board, Component Only

Optimize duct smoke detection reliability with the System Sensor D4P120 4-Wire Photoelectric Power Board. Designed as the component power board for the InnovairFlex D4120 duct smoke detector, the D4P120 delivers dependable monitoring with low standby current, simplified wiring using SEMS screws, and secure mounting to a standard electrical box. Field sensitivity metering (when used with RTS2/RTS2-AOS and SENS-RDR) helps you meet NFPA 72 requirements without lengthy bench testing, while the built-in test switch and remote Test/Reset support simplify routine inspections and reduce downtime. The removable cover and insect screen make maintenance fast, and the compact, low-profile design integrates cleanly into security and surveillance systems that require unobtrusive duct smoke detection. Ideal for facility managers, integrators, and security teams who need a reliable power-board component for duct-mounted photoelectric detectors. Add the D4P120 to your next duct smoke detection upgrade or contact us to specify this component for your monitoring and safety application.
