Lifesafety Power RC75/150-C16 Rackmount Dual-Voltage Lock Control

Overview

The RC75/150-C16 is a rackmount DC power distribution and lock control module that manages 16 solenoid lock outputs in a single 1U form factor. It supplies dual-voltage power — 12V at 6A and 24V at 6A — from a shared internal power supply, allowing you to run mixed-voltage access control systems (keypads, maglock solenoids, electric strikes) without separate bulk power supplies scattered across the cabinet. This is the right choice for access control installations where you need centralized power management for entry gates, server room doors, equipment cabinets, or perimeter security zones.

Compatibility

The RC75/150-C16 integrates with access control panels and power distribution architectures that use 12V or 24V DC solenoid locks and electronic strike mechanisms. Verify that your control system outputs low-voltage dry-contact relay signals or 0–10V analog control to trigger the module's lock outputs. The 16-output design accommodates standard electromagnetic locks, buzzer releases, door strikes, and gate operators in parallel or series configurations — check your solenoid current draw against the 6A per-voltage-rail limit. Compatible with distributed access control systems running Lifesafety Power infrastructure, legacy hardwired relay logic, or modern ONVIF-capable access control appliances that supply relay closure or analog trigger signals.

Installation Notes

Mount the RC75/150-C16 in a 1U rack space with adequate airflow around the rear power connectors and terminal blocks. Incoming AC mains and low-voltage lock trigger wiring connect via screw terminals — use 18 AWG to 12 AWG wire for lock solenoid returns and control signal inputs depending on current draw per output. Ensure the control panel's relay output ratings match the RC75/150-C16's input logic levels (typically 12–24V DC logic, not line voltage). Each solenoid circuit should include a back-EMF suppression diode on the lock coil return to protect solid-state output drivers. The internal power supply is short-circuit protected, but oversized loads on a single output rail (>6A sustained) will trigger shutdown — distribute high-current locks across both 12V and 24V rails when possible. Verify local electrical code compliance for emergency egress locks, fail-safe interlock requirements, and battery backup integration if the installation is life-safety-critical.
