Security Door Controls 602RF 1 A 12/24 VDC Fire Relay Power Supply

Provide regulated low-voltage power for an access-controlled opening while keeping fire-alarm interface and standby-battery charging functions in the same enclosed assembly. Security Door Controls 602RF supports 12 VDC or 24 VDC applications at up to 1 A, making it suited to controlled-door hardware and associated access control equipment that require a dedicated protected power source. The integrated fire relay provides a connection point for fire-system release requirements, while the battery charger supports a backup-power arrangement within the power enclosure. This combination reduces the need to assemble separate supply, charging, and relay components around a single opening or small controlled-door circuit. The cabinet measures 11 x 11 in, providing an enclosed installation location for the power system. Select this model where output voltage must match either a 12 VDC or 24 VDC device circuit and where 1 A capacity meets the connected load. Its integrated fire relay separates it from a basic standalone DC supply, and the charging function distinguishes it from a power source without battery support. Verify connected-device voltage, current demand, fire-system wiring requirements, and battery requirements before installation.
