Lifesafety Power FPO250/250-3C8P5D8PE12M/P24-A Dual Voltage Access Control Power System
Overview
The FPO250/250-3C8P5D8PE12M/P24-A is a UL-listed power supply and access control module platform delivering 500W total output across dual-voltage channels. It integrates 24 relay-based lock outputs and 40 auxiliary power-limited outputs in a single 48″H × 36″W × 8.5″D enclosure, pre-wired for rapid commissioning. This architecture eliminates separate power and control infrastructure — lock supervision, battery charging, fault detection, and door-unlock signaling all converge in one cabinet, reducing wiring labor and panel real estate in security closets, server rooms, and multi-door access deployments.
Key Features
- Dual-voltage output by zone: 12V and 24V channels assignable per output, accommodating legacy and modern lock hardware without converters.
- 24 relay lock outputs (3 C8P boards): 2.5A Class 2 power-limited per channel, each programmable for failsafe/failsecure, supporting both voltage and dry-contact logic.
- 40 auxiliary outputs (5 D8P boards): 2.5A Class 2 outputs for door strikes, magnetic locks, or sensor power across 12V or 24V buss per zone.
- Fire alarm disconnect: Dedicated relay triggers automatic door unlock on fire panel signal — meets life-safety code integration without external relay logic.
- Battery backup with charger: Integrated fast charger prolongs cell life; low-battery cutoff prevents over-discharge and premature backup failure.
- Fault monitoring: AC and system fault Form C contacts (dry relay) triggered by low/no battery, ground fault, supply failure, or blown fuse — direct integration into access control or VMS alarm inputs.
- OutSmart dual-color LEDs: Per-zone status indication (12V green, 24V blue) for field diagnostics without meter or software.
- Optional Netlink module: Remote battery testing, power supply health monitoring, and integration into NetLink dashboard for 24/7 supervision.
- Enhanced surge immunity: Input and output surge protection rated for utility and load transients.
Compatibility
The enclosure pre-wires for one LP1502 module and eleven MR52 modules — compatible with LifeSafety Power reader and relay control boards. The 3 C8P, 5 D8P, and E12M/P24-A module stack integrates directly into Panduit rail systems and existing access control wiring schemes. Consult LifeSafety Power documentation for reader-board and third-party panel integration specifics.
Installation Notes
Enclosure dimensions: 48″H × 36″W × 8.5″D. System weight: 114.65 lbs — wall or rack mount with appropriate structural support. 120 VAC input; dual 12V/24V output bussing hardwired per zone. ProWire factory pre-termination includes lock control, tamper, fault, and communication connections — verify all connections before energizing. Fused inputs protect against short to ground and supply faults.
