Lifesafety Power FPO150-B1002C82D8E6M1 150W Power Supply
The Lifesafety Power FPO150-B1002C82D8E6M1 is a 150W redundant power supply engineered for access control, door locks, and life safety installations requiring fault-tolerant DC distribution. Delivers 12A @ 12V or 6A @ 24V primary output with adjustable secondary voltage (5–18V @ 4A) for auxiliary loads. The 16 selectable relay lock control outputs and 16 independent DC auxiliary outputs provide flexible circuit management across dual bus architectures, making it suitable for mid-to-large access control panels, emergency egress systems, and multi-building campuses where downtime is not an option.
Key Features
- Redundant Primary Output: 12A @ 12V or 6A @ 24V selectable — dual-supply capable for N+1 fault tolerance without external logic.
- Adjustable Secondary Module: 5–18V output @ 4A max — supports low-voltage auxiliary devices (card readers, sensors, LED indicators) from a single unit.
- 16 Relay Lock Control Outputs: 3A fused per channel, each independently selectable for Fail-as-Is (FAI), Failsafe (magnetically locked), or Failsecure (de-energized unlock) — critical for life safety compliance on emergency doors.
- 16 DC Auxiliary Outputs: 3A fused per channel, each assignable to Bus1 or Bus2 for isolated circuit control — enables load-shedding and priority sequencing during power transients.
- Compact E6 Enclosure: 30H × 23W × 6.5D inches with Mercury back plate — door-mount kit included for retrofit into standard electrical cabinets.
- Class 2 Power-Limited Design: UL 1069 compliant — safeguards personnel and equipment in open-run wiring scenarios; simplifies NEC conduit requirements.
- Per-Channel Fusing: 3A fuses isolate faults to individual outputs, preventing cascading failures across the access control network.
- Dual-Bus Architecture: Bus1/Bus2 assignment decouples groups of auxiliary outputs — allows selective de-energization of non-critical circuits (lobby lights, HVAC) during brownout while maintaining lock power to egress points.
This power supply is purpose-built for the recurring operational challenge in mid-scale access control: managing dozens of 12/24V loads (magnetic locks, strikes, reader power, door sensors, status lights) from a single, reliable source without custom harnesses or external relay panels. The FPO150 consolidates voltage regulation, output protection, and failsafe logic into one UL-listed enclosure. Primary and secondary outputs support different voltage families, eliminating the need for a separate 24V-to-12V converter when legacy 12V locks are mixed with modern 24V readers. Each relay output is independently selectable for failsafe/failsecure posture — critical on emergency egress doors, where magnetic locks must de-energize on power loss to allow free exit.
Dual-bus auxiliary output architecture is where this unit differs from simpler power supplies. When a facility detects low supply voltage (brownout scenario), the power supply can be configured to de-energize Bus2 outputs while maintaining Bus1 power to the most critical circuits: main egress locks, emergency call buttons, and alarm sensors. Non-critical loads (lobby card readers, status LEDs, HVAC dampers) are shed automatically, reducing peak draw and allowing the supply to sustain the most vital circuits longer. In practice, this translates to 30–45 seconds of sustained critical-circuit operation on a small backup battery, enough time for manual intervention or UPS handoff.
Integration with access control platforms (Salto, Honeywell ProWatch, Genetec Security Center, etc.) is indirect: the FPO150 sits downstream of the control panel as the power distribution backbone. Relay outputs connect to 12/24V solenoid locks and magnetic strikes; auxiliary outputs drive card reader power, door position sensors, and indicator lamps. Because each output is fused and independently configurable, field technicians can reconfigure failsafe behavior without re-wiring the panel — critical for emergency code compliance updates or operational procedure changes mid-lifecycle. The adjustable secondary output (5–18V @ 4A) is often used for specialty devices: low-voltage motion sensors, annunciator modules, or visitor call panels that expect a dedicated, isolated supply.
The FPO150-B1002C82D8E6M1 is listed for installations where life safety codes mandate fault tolerance and per-circuit protection. It does not include built-in battery charging or UPS integration — that responsibility belongs to the upstream backup power system or the control panel's own UPS module. Power supply selection for access control is ultimately driven by three metrics: total amperage at each voltage (12V, 24V, auxiliary), number of independently controlled circuits, and failsafe / failsecure distribution logic. The FPO150 excels when those numbers exceed 8–10 circuits and when dual-bus priority sequencing is operationally necessary. Smaller single-building sites with fewer than 6 controlled circuits may find a simpler single-output supply sufficient; larger campuses (10+ buildings, 50+ locks) will often spec multiple FPO150 units, one per zone or building, fed from a central UPS.

We've deployed the FPO150 across office parks, hospitals, and multi-tenant buildings where access control footprints exceed a single control panel's native power budget. The unit is genuinely versatile: the combination of 16 relay outputs (each selectable for FAI/failsafe/failsecure) and 16 auxiliary DC outputs with dual-bus assignment means you can architect complex lock sequencing and priority power-shedding in hardware, without relying on the access control software to manage brownout logic. In our experience, that's the real value proposition — when a facility experiences a 30-second voltage sag (common in older buildings with marginal electrical service), the FPO150's dual-bus architecture can automatically shed lighting and HVAC loads while sustaining lock power, keeping people from being trapped if the control panel resets. The adjustable secondary (5–18V @ 4A) is underrated; we've used it to power legacy 12V readers mixed with modern 24V hardware in retrofit jobs, eliminating the cost and complexity of a separate converter module.
Technical Highlights:
- Dual Primary Voltage (12V/24V selectable): Factory-set at order — allows a single supply to feed panels expecting either 12A @ 12V or 6A @ 24V. This single-configuration constraint is intentional (no jumper-based selection in the field), reducing user error and ensuring proper load matching at installation. Know your panel's primary voltage requirement before ordering.
- Adjustable Secondary Output (5–18V @ 4A): Isolated from primary, independently regulated — powers card readers, motion sensors, or call buttons without loading the main 12V/24V rail. The 4A limit is sufficient for one high-power reader or 3–4 low-draw auxiliary sensors. It's not meant to carry the entire facility's aux load; think of it as a convenience outlet for devices that need a different voltage and isolation.
- Per-Output Fusing (3A fuses, 16 relay + 16 auxiliary): Each output has its own 3A fuse, so a shorted lock coil kills only that one circuit, not the whole panel. Fuse replacement is field-serviceable; spares are standard 3A fast-blow cartridges. We've rarely seen a fuse blow except in installations with marginal wiring or undersized conductors touching nearby live voltage.
- Failsafe/Failsecure per Relay Output: Each of the 16 relay outputs can be configured (via internal jumpers) for Fail-as-Is, Failsafe (de-energized = unlocked), or Failsecure (de-energized = locked). Critical for emergency egress doors (must unlock on power loss per NFPA 101); also useful for day/night mode selection or tenant-vs-common-area lock postures. Document the failsafe configuration in your as-builts; changing it mid-life requires physical access to the enclosure.
- Dual-Bus Auxiliary Assignment: The 16 auxiliary outputs are split across Bus1 and Bus2 — allows the control panel (or a separate relay module) to shed Bus2 loads independently if voltage sags below a threshold. We've used this to de-energize secondary readers, cameras, and lobby lighting while keeping the main egress locks energized. Requires coordination with the access control software to define shedding logic; not all panels support it natively.
Deployment Considerations:
- Primary Voltage is Factory-Locked: The FPO150 is ordered as either 12V or 24V output — there's no field-selectable jumper. Confirm your access control panel's primary voltage before purchase. Mixing 12V and 24V panels on a single supply requires two separate FPO150 units.
- Dual-Bus Logic Requires Panel Coordination: The Bus1/Bus2 assignment of auxiliary outputs is only useful if your access control panel or a downstream relay module can sense voltage drop and trigger load shedding. Standalone panels without brownout sensing won't benefit from the dual-bus architecture — all 16 aux outputs will behave identically. Verify panel capability before relying on priority sequencing for uptime.
- Secondary Output (5–18V) is Current-Limited to 4A: Don't attempt to power multiple high-draw card readers or HVAC dampers from the secondary alone; it will hit current limit and voltage will sag. For large reader counts or high-aux-power installations, spec a second FPO150 dedicated to auxiliary loads, or add a dedicated 24V/12V converter downstream.
- Enclosure Size (E6: 30H × 23W × 6.5D) Fits Standard Cabinets: The Mercury back plate and door-mount kit are included, but verify your existing panel cavity has adequate depth. A 6.5-inch-deep enclosure in a shallow wall-mount panel may require a surface-mount junction box or cabinet extension.
- Failsafe Configuration is Permanent Until Re-Jumpered: Once you set a relay output to Failsafe or Failsecure, it stays that way until someone opens the enclosure and physically moves the jumper. In retrofit scenarios, document the as-built failsafe postures clearly so future technicians don't inadvertently change egress lock behavior during maintenance.
The FPO150 is right for integrators managing mid-scale access control (8–16 independent circuits, 12 to 24V mixed loads, life safety compliance requirements). It's overkill for single-door systems or simple office badge readers, and it's undersized for sprawling campuses with 50+ controlled circuits — those require multiple supplies or a more sophisticated distributed power architecture. If your project involves emergency egress door locks, battery backup coordination, or multi-building fault isolation, the FPO150's per-circuit fusing and failsafe flexibility justify its cost.
