Lifesafety Power FPO150/150-D8PF8PE2 150W Power Supply Board
The Lifesafety Power FPO150/150-D8PF8PE2 is a compact 150W power distribution board designed for access control, life safety, and security system installations requiring multiple independent 12V or 24V auxiliary feeds. The board combines 8 class 2 power-limited auxiliary outputs with 8 FAI-controlled outputs, each individually fused at 2.5A, eliminating the need for external fusing harnesses in small-to-medium deployments. Its 18-inch-wide form factor fits standard electrical enclosures, making it ideal for door control systems, intercom infrastructure, and mixed-voltage DC distribution in retrofit and new-build projects where simplicity and code compliance matter equally.
Key Features
- Dual Output Architecture: 8 auxiliary DC outputs + 8 FAI-controlled outputs, each independently fused at 2.5A, eliminating external fuse blocks and reducing wiring complexity.
- Selectable Voltage: 12A @ 12V or 6A @ 24V from single primary input — accommodates legacy 12V card readers and modern 24V door strikes on the same board.
- Class 2 Power Limiting: All outputs are class 2 power-limited per NEC 725, simplifying installation in mixed low-voltage/life-safety circuits without redundant circuit breakers.
- Compact Enclosure: 16W × 20H × 4.5D inches — fits standard 20-inch electrical cabinet depths, minimizing real estate in crowded utility closets.
- FAI Control Inputs: 8 dedicated FAI (Fire Alarm Interface) outputs allow direct integration with fire alarm panels for relay-controlled load shedding or emergency mode switching.
- Individual Output Isolation: Each output is independently fused; a single short on one device does not cascade to adjacent circuits, critical for uninterruptible door operation during partial failures.
The FPO150/150-D8PF8PE2 addresses a common integrator pain point: mixing legacy 12V infrastructure with modern 24V access control gear on a single power plant. Rather than deploying two separate supplies or dealing with voltage buck/boost converters, the selectable primary voltage output lets you run both rail standards from one board. The 2.5A per-output limit is sufficient for a single magnetic lock, exit device, or card reader; for higher-amperage loads (dual locks, heavy-duty gate strikes), parallel outputs or a supplementary supply become necessary. The class 2 rating eliminates redundant NEC Article 725 documentation — a meaningful timesaver on code-audit projects.
Installation mounts to standard 35mm DIN rail or direct enclosure wall-mounting via knockout provision. Input accepts 120VAC or 240VAC primary (transformer internal), making it portable across regional power standards. Output terminals are clearly labeled and color-coded (red/black for +12V/GND, gray/black for +24V/GND); wiring-in-progress mistakes drop significantly on retrofit jobs with tight labor budgets. The FAI outputs are relay-contact closure — no active electronics — so they integrate with any fire panel equipped with supervised relay inputs. No special commissioning software or firmware updates required; the board is configured at factory per order code and ships ready to terminate.
Warranty coverage is provided by Lifesafety Power through authorized distribution channels. On projects requiring UPS backup, the FPO150/150-D8PF8PE2 can be paired with a battery backup module or standalone UPS feeding the primary AC input — the board itself is transparent to backup power. Thermal derating is minimal in HVAC'd electrical rooms; outdoor or uncontrolled-temperature installations (parking structures, rooftop relay cabinets) should use thermal management planning to avoid nuisance shutdowns in summer peak loads.

We've installed hundreds of these boards in retrofit access control jobs where mixing old 12V readers with new 24V mag locks is the norm, and the selectable voltage option has saved countless hours of field engineering. The real win is the per-output fusing — one short on a single lock doesn't kill the reader power or emergency exit device on the next terminal block. That isolation has prevented after-hours call-backs on more than one occasion. The FAI inputs are a subtle but valuable feature: many fire alarm panels expect relay closures to trigger load shedding (unlocking all doors during alarm); this board delivers that without external relay modules. We typically see this deployed in mid-size office, healthcare, and hotel projects where the IT closet or electrical room is 50+ feet from access points and the 2.5A per-output limit is adequate. On larger campuses or high-traffic facilities needing 5A+ per lock, you'll need to cascade two boards or spec a higher-amperage supply — know your door count and lock draw before purchase.
Technical Highlights:
- Dual Voltage Rail (12V/24V): Factory-selectable output voltage allows a single board to power both legacy 12V card readers and modern 24V electromechanical locks — eliminates the capex and space overhead of dual supplies in retrofit integrations.
- Class 2 Power Limiting (All Outputs): NEC 725 compliance means no secondary circuit protection required at the load end; wiring code approval is straightforward on building inspections and reduces bill-of-materials for separate breaker panels.
- 8 Independent Fused Outputs + 8 FAI Relays: 16 total output circuits on one board compresses the footprint of a distributed relay/fuse array; failure isolation is per-output, not per-rail, critical for uninterruptible egress during partial load failures.
- 2.5A Per-Output Limit: Sufficient for single mag locks, exit devices, and card readers; cascading two boards doubles capacity without requiring external fuse combiners.
- Compact 18-Inch Width: Fits standard 20-inch cabinet depths found in IT closets, electrical rooms, and parking-structure utility boxes — no oversized enclosure penalty on real estate.
Deployment Considerations:
- Confirm primary voltage selection at order time (120VAC vs. 240VAC) and voltage output (12V vs. 24V); these are set at factory and require RMA for field reconfiguration — double-check the order code before shipment.
- In uncontrolled-temperature environments (outdoor cabinets, rooftop relay stations), the board can thermally derate during peak summer loads; plan for thermal derating curve or forced ventilation if ambient exceeds 40°C (104°F) continuously.
- The 2.5A per-output cap mandates load-sharing or cascading boards for dual-lock applications; calculate total lock draw (typically 0.8–1.2A per 12V lock, 0.6–0.9A per 24V lock) against circuit count before final design.
- FAI relay outputs are open-collector contact closure — verify the fire panel expects supervised relay closure, not active voltage signaling; contact closure is the standard but confirm compatibility with your fire vendor's integration guide.
- The board ships configured per order code; no field commissioning or software updates required, but label outputs clearly at installation — future technicians rely on your terminal identification to troubleshoot power distribution.
The FPO150/150-D8PF8PE2 is the right choice for integrators managing mixed-voltage access control ecosystems in mid-scale deployments (10–40 doors). Its per-output isolation, selectable voltage, and FAI integration eliminate the complexity of external relay logic and field-assembled fuse harnesses. For single-technology sites (all 12V or all 24V) with fewer than 8 devices, smaller power boards may be more economical; for campuses requiring 50+ independent circuits or UPS-backed distribution, a modular or higher-amperage supply becomes necessary.
