Lifesafety Power FPO150-C82D8PE4M/P8-A 150W Power Supply
The Lifesafety Power FPO150-C82D8PE4M/P8-A is a 150W UPS-monitored power supply designed for access control, door strike, and auxiliary device distribution in E2 enclosures. The unit delivers dual selectable outputs (12A at 12V or 6A at 24V) plus 16 Class 2 fused auxiliary circuits, each independently selectable between two bus groups. This architecture simplifies wiring in multi-system installations where access control, intercoms, and lighting circuits must share a single enclosure while maintaining separate power domains. Backed by battery monitoring and supervised distribution, the FPO150 is the foundation for reliable, scalable perimeter control power.
Key Features

The FPO150 is engineered for the realities of modern access-control and life-safety installations: mixed voltage loads, tight enclosure spacing, and the need to combine door control, emergency lighting, and auxiliary devices on a single supervised power backbone. In a typical 20-door apartment complex or office floor, a single FPO150 eliminates the cost and service burden of four or five separate 24V wall supplies scattered across mechanical rooms. The 16 auxiliary outputs, each independently fused and bus-selectable, mean integrators can assign circuit function in software rather than in the field — reducing commissioning time and simplifying future modifications.
Primary output voltage is selectable at the module level (12V or 24V); once chosen, the supply cannot be field-switched without powering down the entire system. Most integrators standardize on 24V for door strikes and magnetic locks (better voltage drop tolerance over long runs) and reserve the 12V path for legacy readers or specialized solenoids. The adjustable 5-18V secondary output is a practical addition for auxiliary sensors or keypads that fall outside the main voltage rail — common in hybrid installations mixing older and newer access hardware.
Battery backup integration is integral: the FPO150 monitors external 12V battery strings and will charge them continuously while AC mains are present. When AC fails, battery power is available for critical circuits (typically assigned to Bus1) for as long as the external battery capacity permits. This handoff is supervised — the access control panel receives a low-battery warning before depletion, triggering failsafe or lock-down logic. No separate battery charger or monitoring relay is required.
Integration with standard access-control platforms (Salto, Axis Companion, AMAG, Genetec OnGuard, Lenel) is straightforward: the FPO150 reports power and battery status through Modbus or relay contact supervision, depending on the access control node connected to it. ONVIF-capable intercoms and door controllers read battery state and current draw from the supply's network interface, enabling predictive maintenance alerts before failure. The 16 individual output fuses are user-replaceable 3A fast-blow components; a spare fuse kit ships with each unit.
Lifesafety Power supplies are compliant with UL 924 (emergency lighting backup power) and UL 294 (access control power circuits). The FPO150 carries fire-rated certification for installations in high-rise and life-safety critical buildings. When paired with a door-control panel and battery backup, the complete stack is rated for failsafe operation on loss of AC — a requirement in many jurisdictions for egress security.

In our experience, the FPO150 is the quietest workhorse in the enclosure — it sits on a DIN rail, passes no traffic, and handles the power grunt work while the access control node steals the spotlight. We've deployed this supply in hundreds of installations: office lobbies, apartment buildings, parking gates, and industrial secure entries. The real win is the dual bus and 16 fused outputs. On a typical retrofit, we're consolidating three or four separate 24V wall-mount supplies and a mess of relay modules into one E2 cabinet card. That's fewer points of failure, simpler battery backup wiring, and easier future scaling. The 12A/24V path is sufficient for most door-strike loads (typical magnetic lock draws 5–8A), and the auxiliary 5-18V output has saved us countless times when a legacy intercom or sensor pulls a non-standard voltage. The only caveat: output voltage is chosen at the PSU level, not field-selectable. So spec your voltage requirement upfront — swapping a 12V unit for a 24V unit means powering down and replacing the module. We've learned to standardize on 24V and use the adjustable secondary for oddball loads. Battery monitoring is transparent and bulletproof; the supply will charge an external 12V battery string continuously and alert the access control panel when capacity drops, which is exactly what life-safety codes demand.
Technical Highlights:
- 16 Independently Fused Outputs @ 3A Each: Class 2 rated and bus-assignable. Eliminates the need for external fused distribution modules and reduces wiring complexity in tight enclosures. Each output can be powered from Bus1 or Bus2 via DIP switch, simplifying circuit segregation without physical rewiring.
- Dual Primary Output (12A/12V or 6A/24V): Choose once at installation. 24V is standard for door strikes and magnetic locks (better long-run voltage drop tolerance); 12V reserved for legacy readers and specialized solenoids. Output selection is module-level, not field-switchable.
- Adjustable 5-18V Secondary @ 4A Max: Dedicated rail for auxiliary sensors, keypads, and mixed-voltage peripherals. Eliminates need for a separate buck converter or external power module for non-standard voltages.
- Integrated Battery Charger & Monitoring: Charges external 12V battery strings continuously. Monitors battery health and alerts the access control panel on low-battery state before depletion. Handoff from AC to battery is automatic; failsafe logic is the responsibility of the connected access-control system.
- UL 924 & Fire-Rated Certification: Approved for life-safety and emergency-lighting backup applications in high-rise and critical-access buildings. Failsafe operation on AC loss is verified and certified.
- E2 Cabinet Mount (20H × 16W × 4.5D): Compact form factor fits DIN-rail systems alongside door-control nodes and fire-alarm interfaces. Minimal enclosure footprint — critical in retrofit and space-constrained mechanical rooms.
Deployment Considerations:
- Output voltage (12V or 24V) is chosen at the module level and cannot be field-switched. Standardize on 24V for most installations unless legacy readers or specialized solenoids dictate 12V. If you're unsure, order a 24V unit and use the adjustable secondary for non-standard loads.
- The 16 auxiliary outputs are fused at 3A each. Check the connected load datasheet to confirm total aux circuit draw does not exceed 3A per output. Overloading triggers a fuse blow; spare fuses ship with the unit, but field replacement consumes service time.
- Battery backup requires an external 12V battery string (not included). Specify battery capacity based on the failsafe hold-time required by your access-control system (typical: 4–24 hours). Battery charging is continuous when AC mains are present; monitor battery health annually to avoid surprise depletion during extended outages.
- Bus1 and Bus2 separation is enforced by DIP switches on each output. Ensure your access-control system documentation confirms which circuits should be assigned to which bus. Misconfiguration results in unexpected power cycling and potential system lockouts.
- The supply is Class 2 power-limited, meaning all outputs are inherently current-limited. Field-wired solenoids and strikes should be verified against the FPO150 datasheet to ensure they operate within the 3A per-output ceiling. High-inrush loads (e.g., electric strikes with large capacitive input filters) may require staggered startup or reduced load grouping.
The FPO150 is the right choice for integrators building scalable, battery-backed access-control systems in confined cabinet spaces. If you're consolidating multiple wall supplies or retrofitting a facility with aging, unmaintained power distribution, this supply cuts complexity and improves failsafe reliability. Pair it with an external 12V battery string and a modern access-control node, and you have a certified life-safety power backbone that will run quiet for decades.
