Lifesafety Power RC150B-C8D8 Rackmount Dual Voltage Lock Control
Overview
The RC150B-C8D8 is a rackmount power control unit that supplies dual-voltage DC output for access control systems. It delivers 12V@4A and 24V@4A simultaneously, with 8 dedicated lock control outputs and 8 auxiliary outputs — solving the integration problem where a single power rack must feed mixed-voltage solenoid locks, strikes, and auxiliary relay loads across a multi-door access control installation. This is the control layer that bridges your access control panel to distributed field devices without needing separate power supplies per voltage class.
Compatibility
The RC150B-C8D8 integrates with standard 19-inch rackmount access control ecosystems. It pairs with legacy and modern door controllers that require dual 12V and 24V DC feeds. The 8 lock outputs and 8 auxiliary outputs support common solenoid strikes, magnetic locks, and relay-driven door hardware across Lifesafety Power installations and compatible third-party access control panels that use isolated 12V or 24V logic. Verify your panel's output isolation and voltage requirements before integration — mixed-voltage systems demand careful wiring to avoid cross-voltage faults on shared grounds.
Installation Notes
Mount the RC150B-C8D8 in a standard 19-inch rack alongside your access control panel. Provide AC mains input (confirm voltage rating from your unit's label) to the internal transformer. Wire each lock output pair (12V and 24V banks) to its corresponding solenoid or strike according to the device datasheet — mismatched voltage on a solenoid coil will shorten its life. All 8 auxiliary outputs draw from the same rails; total load across all outputs must not exceed the rated current per rail. Use appropriately gauged wire for the distance from rack to field devices; voltage drop over long runs (>50 feet) to distant locks will reduce energizing force. Ensure the access control panel's output logic is isolated or properly buffered before connecting to the relay inputs on the RC150B-C8D8 to prevent ground loops.
