Lifesafety Power FPO250-2C8P3D8PE6M1/P16-A Power Supply Board 250

Lifesafety Power FPO250-2C8P3D8PE6M1/P16-A Access Control Power System with Battery Backup

Overview

The FPO250-2C8P3D8PE6M1/P16-A is a UL-listed, single-voltage power supply system designed to centralize power distribution and battery backup for multi-door access control installations. The unit combines 250W total output capacity with dual-voltage switchable modules, serving 16 relay lock outputs and 24 auxiliary outputs in a prewired, 30-inch tall enclosure. This is the system to deploy when you need managed fault reporting, automatic fire alarm door unlocking, low-battery protection, and visual status indication across multiple access control zones without custom wiring.

Compatibility and Integration

The FPO250-2C8P3D8PE6M1/P16-A accepts 120 VAC input and delivers switchable 12V or 24V outputs per zone, making it compatible with standard Class 2 power-limited access control architectures. The enclosure ships prewired to support one LP1502 board and seven MR52 expansion boards, allowing you to scale door control and auxiliary circuits without additional integration labor. AC fault and system fault Form C relay contacts trigger on low/no battery, short-to-ground, supply failure, or blown fuse — critical for integrating with central monitoring or building management systems that require real-time status.

Key Features

• Fire Alarm Disconnect: Automatically unlocks doors on fire alarm signal, meeting life-safety code requirements without additional relay logic.
• Low-Battery Cutoff: Prevents deep discharge of backup batteries, extending cycle life and ensuring reliable failover during extended outages.
• Dual-Voltage Zone Switching: Each of the 2 C8P relay modules and 3 D8P auxiliary modules supports independent 12V or 24V selection per zone via OutSmart dual-color LEDs (green 12V, blue 24V).
• Enhanced Surge Immunity: Built-in surge protection on input and output stages protects connected locks and readers from transient damage.
• Programmable Lock Outputs: 16 relay outputs (2.5A Class 2 each) configure as failsafe, failsecure, FAI, or dry relay with NC/NO logic per zone.
• Optional Network Monitoring: Netlink module support adds real-time remote battery testing and power supply status visibility from a centralized dashboard.

Installation Notes

The enclosure measures 30.0H × 23.0W × 6.5D inches and weighs 49.20 lbs, fitting standard 30-inch electrical racks with Panduit cable management pre-installed. Input requires 120 VAC; verify available amperage before installation. Fused outputs protect each zone; replace fuses matching the load rating of connected locks. Prewired harnesses to LP1502 and MR52 boards eliminate field termination for the primary configuration, reducing integration time and wiring errors. Fire alarm and tamper switch inputs are factory-landed and ready for supervised connection.
