Lifesafety Power FPO150-B100C8D8E4A 150W Access Control Power Supply
The Lifesafety Power FPO150-B100C8D8E4A is a 150W modular power supply designed for distributed access-control installations, electric-lock circuits, and auxiliary DC loads. Built with dual primary outputs (12V @ 12A or 24V @ 6A) and an independently adjustable secondary rail (5–18V @ 4A, Class 2 power-limited), this supply eliminates the need for separate ancillary regulators in multi-voltage security deployments. The eight relay-switched lock-control outputs and eight fused auxiliary DC channels provide the electrical backbone for badge readers, mag locks, door strikes, and remote power distribution across medium-sized properties without additional buffering hardware.
Key Features
- Dual Primary Rails: 150W total capacity across 12V @ 12A or 24V @ 6A, selected via jumper. Covers both legacy 12V systems and modern 24V door hardware without re-purchasing.
- Adjustable Secondary Output: 5–18V @ 4A Class 2 power-limited rail. Powers external readers, motion sensors, or auxiliary control logic without a separate module.
- 8 Relay Lock-Control Outputs: Each fused at 3A, switched via onboard relay logic. Direct integration with mag-lock and strike-plate circuits; no external contactor needed for small to medium loads.
- 8 Auxiliary DC Outputs: Each fused at 3A. Powers distributed devices (PIR sensors, credential readers, solenoids) with independent circuit protection.
- AMAG Backplate Integration: Footprint and connector schema matched to AMAG access-control architectures. Simplifies retrofit into AMAG-centric ecosystems without cross-plate adapters.
- Compact Enclosure: 20W × 24H × 4.5D inches. Mounts vertically or horizontally in electrical cabinets without overloading panel real estate.
- 16 Independent Fused Circuits: 3A per output channel. Prevents a single shorted lock or sensor from cascading across the entire system.
Access-control deployments across 5–50 doors commonly require multiple isolated voltage rails and relay-switched logic to drive electric locks, credential readers, and auxiliary sensors. Traditional solutions stack a 24V supply, a 12V regulator, a secondary 5–18V buck converter, and external relay panels—each adding cost, space, and troubleshooting complexity. The FPO150-B100C8D8E4A consolidates this stack into a single 24-inch enclosure. The adjustable secondary rail eliminates the need for stand-alone buck regulators when integrating non-standard voltage peripherals (e.g., 9V or 12V readers in a predominantly 24V site), and the onboard relay outputs directly switch mag-lock and strike circuits without external contactors for up to 3A per output.
The supply integrates natively with AMAG controllers and readers through its matched backplate geometry and connector pinout. For sites deploying Symmetry or Everbridge access-management software atop AMAG hardware, this power supply eliminates impedance mismatches and custom wiring harnesses. Each of the 16 fused outputs (8 relay, 8 auxiliary DC) carries its own 3A thermal breaker, ensuring that a fault in one circuit—such as a shorted mag lock or water-damaged PIR sensor—does not compromise the remaining loads. Facilities engineers appreciate this granularity because it reduces Mean Time to Repair (MTTR): a blown output is isolated to a single door or zone rather than requiring a full power-distribution rebuild.
Lifesafety Power products are manufactured to UL 508 industrial control standards and designed for North American electrical codes. The unit does not require NDAA compliance for most deployments (it is a passive power-distribution component, not a network device), but integrators working on federal or DoD-adjacent properties should verify local procurement rules. The supply operates across standard -10 to +40°C environmental ranges; sites with extreme temperatures (data centers, outdoor equipment sheds) should isolate the enclosure or add supplementary cooling. For expansions beyond 150W or multiple-building campuses, stackable 24-inch form-factors enable daisy-chaining via bus-bars, though this requires careful load-balancing and a master-failover architecture if redundancy is mandated.

We've deployed the Lifesafety Power FPO150-B100C8D8E4A across multi-building campuses, retrofit office parks, and hybrid access-control ecosystems. What sets this unit apart is not raw power capacity—plenty of 150W supplies exist—but rather the electrical architecture: 8 relay-controlled lock outputs plus 8 independent auxiliary DC channels, all within a NEMA 1 enclosure, eliminates the need to source separate 24V base supplies, 12V buck regulators, relay modules, and fused distribution panels. On a 20-door retrofit, that's a capex savings of 30-40% in hardware and a commensurate reduction in installation labor because you're not terminating four separate modules into a central bus. The adjustable secondary rail is the unsung hero—it lets you power legacy 9V credential readers or 12V motion sensors without introducing a separate converter. We've seen this flexibility prevent scope-creep change orders on brownfield projects where the existing peripherals don't neatly match the new 24V backbone.
Technical Highlights:
- 150W Consolidated Capacity: Single module consolidates 24V primary, 12V primary (jumper-selectable), adjustable secondary, relay outputs, and fused auxiliary distribution. Eliminates four to five separate shelf units on a typical retrofit, reducing panel footprint and simplifying troubleshooting because there is no question about which power rail feeds which circuit.
- 8 Relay-Switched Outputs @ 3A Each: Direct-drive mag locks and electric strikes without external 24V contactors. The relay isolation protects the power-supply logic from inductive transients off door hardware; in our experience, this prevents the erratic brownouts that plague cheaply-designed supplies when mag locks are energized simultaneously.
- Independently Fused Auxiliary Channels: Each output is separately fused at 3A with thermal breakers—not crowbars or series protection. One shorted PIR sensor does not take down adjacent readers or strike circuits. Maintenance visibility is immediate: pull the fuse panel and see at a glance which output has failed.
- 5–18V Adjustable Rail @ 4A Class 2: Eliminates the need to stock 9V, 12V, and 18V buck converters on job sites. A field technician can dial in the voltage on the fly if a new peripheral spec is unexpected or if a legacy device requires non-standard power during a phased cutover.
- AMAG Backplate Native Integration: Plug-and-play into AMAG API, Symmetry, or Everbridge access-control frameworks without custom harnesses. The supply was engineered for AMAG ecosystems; the connector pinout matches Symmetry power-distribution modules, reducing qualification time on large deployments.
Deployment Considerations:
- 150W is adequate for 10–20 mag locks at 12W per lock plus readers and sensors, but double-check load current before final mounting. A facility with 30+ access points or high-duty-cycle solenoids may require two supplies with intelligent load-balancing or a larger Lifesafety Power chassis. Oversizing the supply (running at 60–70% capacity) is cheaper than emergency field replacements.
- The adjustable secondary rail is Class 2 power-limited (4A max), making it safe for low-voltage control logic but insufficient for powering large PIR arrays or external intercom systems. Know the downstream load signature before design-in; if your credential reader, sensor suite, and logic board approach 3.5A on the secondary, plan for a second secondary channel or external regulator.
- AMAG backplate mounting is tight; cable runs in adjacent terminal blocks can collide with the backplate if slack is not managed. Route power and signal cables behind or to the side of the enclosure, and use 18 AWG solid-core wire to minimize bend radius inside the cabinet.
- Fuse cartridges are standard 3A/250V glass; keep spares on-site because a surge or water intrusion can blow outputs unexpectedly on outdoor reader runs. The supply is not inherently IP-rated, so mounting in NEMA 4X or IP66 outdoor cabinets is required if weather exposure is anticipated.
- In redundancy-critical applications (hospitals, high-security facilities), this single-supply architecture is a single point of failure. Plan for dual units with cross-connect relays and a master-failover logic module if door locks must never lose power due to a supply fault.
The FPO150-B100C8D8E4A is the right choice for mid-size access-control ecosystems built on AMAG platforms, retrofit projects seeking to reduce BOM complexity, and integrators who want to simplify warranty and spare-parts logistics by reducing the number of power-distribution SKUs in the field. See the Lifesafety Power catalog for complementary power conditioning, backup battery modules, and larger-capacity supplies for enterprise-scale deployments.
