Lifesafety Power FPO250/250-3C85D8PE12M/T24-A Unified Power Sys

In our experience deploying unified power platforms across office parks, healthcare facilities, and multi-tenant buildings, the FPO250/250 is one of the rare products that genuinely simplifies panel assembly without sacrificing control granularity. The dual-voltage zone selection eliminates a real pain point: field integrators no longer have to choose between a 12V system (cheaper, less noise margin on long runs) and a 24V system (more robust for electromagnetically noisy environments). With the FPO250/250, you can zone-select per output — run 24V to remote electronic locks on long runs, 12V to readers in the same cabinet, all from one supply. The fire alarm disconnect is factory-certified, so you don't need a separate relay module and custom logic to unlock on alarm; it's a form C contact that fires on FAI signal, dramatically reducing commissioning risk and liability. We've seen integrators eliminate entire pages of relay logic and wiring diagrams by spec'ing this unit. Battery management is conservative — low-battery cutoff prevents the NVR or lock controllers from brownout, and the dedicated fast charger isn't a trickle circuit; it meaningfully extends battery service life. Netlink dashboard is optional but worth considering on larger deployments — it lets you monitor bank status and run battery self-tests remotely without a technician visit.

Technical Highlights:

• 500W Dual-Voltage Output: Carrier-grade capacity for 20+ doors, CCTV NVR, and reader/lock distribution. Zone-selectable 12V or 24V per output eliminates the capex and footprint of separate supplies and reduces wiring complexity and error risk on large panels.
• 3 Relay Outputs + 40 Auxiliary Outlets: 3A fused relay outputs support failsafe/failsecure lock control and FAI logic; 40 Class 2 outlets (2.5A per zone) feed badge readers, mag locks, and exit devices. Prewired and modular — no cross-voltage mistakes.
• Integrated Fire Alarm Disconnect (FAI): Form C relay certified for life-safety unlock on alarm signal — eliminates external relay module, reduces assembly time, and satisfies AHJ fire code requirements without custom logic.
• Low-Battery Cutoff + Fast Charger: Prevents deep discharge (extends battery life 3-5 years vs. trickle-charged systems) and enables rapid recharge after alarm testing or extended outage. Form C fault contacts report AC loss or fuse blown for immediate NOC awareness.
• Prewired for 12 Doors Out-of-Box: Enclosure ships configured for one LP1502 main board and eleven MR52 expansion modules — ready for lock and reader wiring immediately upon delivery. Reduces field assembly labor by ~40% vs. bare-panel builds.
• Lifetime Warranty: Unconditional lifetime materials and labor — no expiration, no surprise deductible. Unusual in the power-supply market and reflects genuine component confidence.

Deployment Considerations:

• 48-inch height and 114.65 lbs weight require wall mounting with appropriate structural backing — plan rack or panel space early in the design phase. Won't fit standard 19-inch equipment racks; requires custom cabinetry or wall-mount installation.
• Netlink module is optional and sold separately — if remote battery testing or IP dashboard visibility is a requirement, budget for the add-on module and plan network connectivity (Ethernet drop to enclosure). Local LED status is provided without Netlink, so offline operation is fully viable.
• 120 VAC input only — no single-phase 240V option. Site power planning must route standard branch circuit UPS power to the enclosure. Verify site power layout before specifying; some facilities require separate UPS circuits for security vs. life-safety loads.
• Prewiring is factory-set for one LP1502 and eleven MR52 boards. If your deployment requires a different board configuration, contact Lifesafety Power for custom factory prewiring — don't attempt field rewiring of the internal bus structure.
• Fire alarm FAI input is dry contact; verify fire panel output is dry relay or supervised dry contact. Some proprietary fire panels require supervised input — confirm compatibility with AHJ and fire panel documentation before commissioning.

The FPO250/250-3C85D8PE12M/T24-A is the ideal choice for integrators building campuses or multi-floor facilities where central power distribution, battery backup, fire life-safety logic, and modular lock control must coexist in one UL-listed, pre-engineered solution. If your project has 10+ doors, CCTV NVR backup, and an AHJ requirement for certified fire alarm disconnect, this system saves weeks of panel design work and eliminates field assembly risk.
