LifeSafety Power C4 Four-Output Fused Lock Output Module

Provide four independently fused lock-output circuits for electrically controlled doors and other locking-device connections. Each C4 output is fused at 3 A, giving each connected circuit its own protection point rather than placing all four outputs behind one shared fuse. The module supports fail-safe and fail-secure lock operation, covering common electrified hardware behaviors used at controlled openings. FAI support lets the module participate in fire-alarm-interface requirements where lock power behavior must be coordinated with the life-safety system. This matters in access-control installations using electrified locks, strikes, or other locking devices whose release or locking state must follow the selected operating mode. Select the fail-safe or fail-secure configuration appropriate to the connected hardware and site requirements. LifeSafety Power C4-BOXED is the boxed four-output version for installations that need multiple protected lock circuits from one module. Its defining characteristics are the four output count, 3 A fuse rating per output, FAI capability, and support for both common lock operating modes. It fits projects that need to separate lock circuits by opening, device group, or connected hardware type while retaining a consistent lock-power control approach.
