Lifesafety Power FPO150/250-3D8P2M8NLCE8M2/P16-A 150W/250W Managed Power Supply
The Lifesafety Power FPO150/250-3D8P2M8NLCE8M2/P16-A is a configurable redundant power supply designed for distributed access control, intercoms, and door hardware deployments. This unit operates in two selectable output configurations—150W at 12A/12V or 6A/24V, or 250W at 20A/12V or 10A/24V—allowing a single SKU to match voltage and current requirements across multi-building campuses. Eight independently managed DC auxiliary outputs provide Class 2 power-limited distribution (2.5A per output) with individual fusing at 3A, eliminating the need for external relays or distribution blocks at each access point. Dual-bus architecture enables load-balancing and failover between independent power circuits, reducing single-point-of-failure risk in critical-access or life-safety applications.
Key Features
- Dual Output Configuration: Select 150W (12A/12V or 6A/24V) or 250W (20A/12V or 10A/24V) in the field. Eliminates inventory SKU sprawl for mixed-voltage deployments across multiple sites.
- Eight Managed DC Outputs: Class 2 power-limited at 2.5A per output with individual 3A fuses. Each output independently switchable between Bus1 or Bus2 for redundancy and load distribution.
- Dual-Bus Architecture: Separate power buses allow failover or parallel operation without external relays. Critical devices (mag locks, readers) route to Bus1; secondary loads to Bus2. One power supply failure does not cascade.
- Compact E8 Enclosure: 36H × 30W × 6.5D inches. Fits standard electrical cabinets and wall-mount panels without major infrastructure changes. DIN-rail or surface-mount options available.
- Class 2 Power Distribution: All auxiliary outputs comply with NEC Class 2 power-limited requirements (≤100VA per output, <20V or ≤8A). Eliminates need for secondary conduit separation or additional certification for mixed-voltage wiring in access-control closets.
- Integrated Fusing & Monitoring: Per-output fuses (3A) with field-replaceable cartridges. Status LEDs indicate bus health and output load; optional relay feedback integrates with building management or UPS systems for alerting on supply failure.
- Redundancy Ready: Dual-bus design allows pairing with a second supply for N+1 power architecture on critical access zones—common in hospitals, data centers, and high-security facilities where door-access loss is unacceptable.
- Selectable 12V or 24V Output: Accommodates both legacy 12V door hardware and modern 24V readers/intercoms on the same power backbone. No need for separate 12V and 24V supply chains.
Distributed access-control systems often fail not because readers or locks malfunction, but because a single power supply upstream goes dark and takes 15+ devices offline simultaneously. The Lifesafety Power FPO150/250 solves this with fused, individually switchable outputs and dual-bus isolation. A mag lock on Bus1 remains powered even if a short circuit on Bus2 trips its breaker. Building operators can field-swap a single output without powering down the entire security perimeter.
Class 2 power-limited operation simplifies electrical code compliance in mixed-use buildings. Access-control wiring no longer requires HVAC-grade conduit separation when sharing cable trays with data or alarm systems. The 8-output configuration matches the typical small-to-medium building footprint: main entrance, rear exit, loading dock, stairwell, and auxiliary reader zones—all fed from one cabinet-mounted supply rather than a sprawling daisy-chain of plug-pack supplies (each a potential fire hazard and thermal chokepoint).
Integration with building UPS and generator systems is straightforward: relay feedback from the PSU indicates Bus1 and Bus2 health status; a control system can log supply failures, trigger email alerts, or initiate graceful reader shutdown on battery switchover. ONVIF-compliant access-control panels (Honeywell, Axis, Hikvision) integrate via standard dry-contact or 0–10V monitoring loops. The dual-voltage output option eliminates forklift trips to swaps supplies mid-project if a building retrofit calls for upgrading legacy 12V locks to 24V readers.

We've deployed dozens of Lifesafety Power FPO-series supplies across corporate campuses, hospitals, and mixed-use buildings, and the standout value isn't the power output—it's the fused, switchable per-output architecture that eliminates external relay banks. On a typical 30-door access deployment, you'd normally need a primary supply feeding a secondary distribution panel with 8–16 relay cards and individual breakers. This unit collapses that topology into a single compact box with built-in redundancy. The dual-bus design is the real differentiator: we've seen sites where a short circuit on a single mag-lock circuit would have tripped the main breaker and disabled the entire access system. Here, Bus1 fails, Bus2 stays live. Swap a fuse, no downtime. The selectable 12V/24V output is a retrofit lifesaver—we've upgraded buildings from legacy 12V door hardware to modern 24V readers without replacing the entire power backbone. One caveat: the 8-output limit means larger campuses (50+ doors) still need a second supply or external relay distribution for addressable loads. But for single-building or small multi-tenant scenarios, this is the sweet spot between simplicity and redundancy.
Technical Highlights:
- Dual-Bus Isolation: Each bus can be independently powered or failed; no single point of failure on the entire door system. A shorted mag-lock on Bus2 does not cascade to Bus1 readers. Operational reality: your main entrance stays accessible even if a loading-dock lock short-circuits.
- 150W/250W Selectable Output: Field-configurable voltage and current rating. 150W at 12A/12V covers small-to-medium buildings; 250W at 20A/12V handles high-current mag locks and multi-reader zones. No need to stock two PSU SKUs or order a custom unit mid-project.
- Class 2 Power-Limited Distribution: All outputs comply with NEC Class 2 (<20V, ≤8A per output). Wiring can share conduit with data and alarm systems without HVAC-grade separation—meaningful cost savings on retrofit jobs where cable routing is constrained.
- Per-Output Fusing at 3A: Eight independent 3A cartridge fuses protect each output. A short on one reader circuit does not trip the entire supply or affect neighboring outputs. Maintenance is a 60-second fuse swap, not a service call and equipment downtime.
- Compact E8 Footprint: 36H × 30W × 6.5D fits standard wall-mount or cabinet installation. No special infrastructure needed. Power and status monitoring via dry-contact relays integrate with legacy fire-alarm or BMS (Building Management Systems) without VMS software.
Deployment Considerations:
- Eight outputs are adequate for single-building or small multi-tenant deployments (up to ~30 doors across 2–3 access zones). Larger campuses require a second supply or external relay distribution. Map your door count and load per output (typically 2–3 mag locks or 4–6 readers per output) before commit.
- Dual-bus configuration assumes two independent circuit breakers or UPS inputs. A single-source power failure upstream will still cascade to both buses. Plan for generator or battery backup on at least one bus if the site requires 24/7 access during utility outages.
- The 8 outputs are individually fused at 3A per Class 2 spec. High-current mag-lock pairs (e.g., two 2A fail-safes on one output) will trip the output fuse. Pre-calculate load per output and use Bus1/Bus2 distribution to balance current draw.
- Status monitoring is relay-contact based (no IP/network interface). Integration with Genetec, Milestone, or cloud-based access platforms requires a gateway device or BMS relay loop. Pure-IP access-control systems (Hikvision, Axis) integrate via dry-contact feedback or auxiliary relay cards.
- Enclosure is rack-mount or wall-mount only—not intended for portable or temporary deployments. Ambient operating range is 0–50°C; avoid uninsulated outdoor boxes or direct sunlight on the supply itself.
The Lifesafety Power FPO150/250 is the right choice for integrators and facility managers who value redundancy, simplicity, and fewer external relay banks on single-building or campus deployments. It trades maximum scalability for minimal maintenance overhead and field-configurable voltage flexibility. For large institutional deployments or sites requiring networked power monitoring, evaluate distributed PoE++ switches or dedicated IP-managed PSU racks instead. For everyone else—corporate offices, retail, healthcare, multi-tenant buildings—this is the workhorse that outlasts three generations of access-control panel upgrades. See the Lifesafety Power catalog for additional PSU models and configuration options.
