Lifesafety Power FPO250/250-2C82D8E8S 500W Dual Voltage Power Supply
Overview
The FPO250/250-2C82D8E8S is a 500W dual voltage power supply rated for 120 VAC input, designed to support access control and security infrastructure in small to mid-size commercial deployments. The unit provides 16 relay lock outputs and 16 auxiliary outputs, enabling simultaneous control of multiple doors, magnetic locks, exit devices, and auxiliary equipment without daisy-chaining multiple power boards. A compact footprint makes it suitable for wall mounting in electrical closets, server rooms, or equipment racks where space is constrained.
Compatibility
This supply integrates with access control systems and fire alarm panels that require multiple supervised relay outputs for door strikes, mag locks, and auxiliary devices. Verify your control panel's output relay voltage and current requirements (contact your panel manufacturer) before installation — the FPO250/250-2C82D8E8S is designed as a distributed power node rather than a universal retrofit. Confirm that your facility's breaker or UPS can sustain 500W at 120 VAC during worst-case load (all 16 relays energized simultaneously).
Installation Notes
Input voltage must be stable 120 VAC; do not exceed 132 VAC or fall below 108 VAC — fluctuations outside this range may damage the supply or cause nuisance relay drops. Ensure a dedicated 15A or 20A circuit breaker (minimum) is installed upstream. If batteries or UPS backup is required, confirm the UPS can deliver the required wattage and that its output voltage matches 120 VAC. Relay and auxiliary outputs are unsupervised by default — consult your access control system documentation to determine if supervised (end-of-line) resistor configuration is needed on any outputs. All wiring must use appropriately rated wire gauge for the expected current per output; undersized wire creates fire hazard and relay chatter.
