Lifesafety Power FPO150-3C8E4M Mercury Power System 120 VAC 150W

Overview

The FPO150-3C8E4M is a 150W Mercury unified power system designed to centralize power distribution for access control, card readers, electromagnetic locks, and related security devices in small to mid-size installations. Operating from 120 VAC input, it provides 24 relay lock outputs—the standard for door locks and fail-safe devices in commercial security deployments. This model handles the power management load for facilities where you need reliable, supervised power to multiple egress points without running individual circuits to each device.

Compatibility

The FPO150-3C8E4M integrates with Lifesafety Power control panels and any access control system that accepts 24 VDC relay-switched outputs. It pairs with electromagnetic locks (mag locks), electric strikes, request-to-exit buttons, and card reader arrays in integrated security systems. Verify input voltage compatibility with your facility's main power panel—this model requires dedicated 120 VAC service. Output relay configurations support standard lock control protocols used across commercial building automation and standalone access control installations.

Installation Notes

Requires a dedicated 120 VAC circuit sized for 150W continuous load. Install in a temperature-controlled equipment room or wall-mounted cabinet away from high humidity and direct moisture—standard placement alongside your access control panel. Ensure proper grounding per local electrical code. All wiring connections (input power, relay outputs, ground) must be terminated by a licensed electrician. Test relay outputs under load before commissioning to confirm lock activation under full system capacity.
