Lifesafety Power FPO150/250-2M8NLC2SD16E8M2/P16-A 150W/250W Dual-Output Power Supply
The Lifesafety Power FPO150/250-2M8NLC2SD16E8M2/P16-A is a dual-rail uninterruptible power supply (UPS) designed for distributed access-control, door-lock, and surveillance infrastructure on commercial properties. The unit delivers 150W (12A/12V or 6A/24V) in standard operation and scales to 250W (20A/12V or 10A/24V) under extended demand, with an integrated 8-channel managed distribution module (MDM) that fuses each output at 3A per circuit. This configuration eliminates the need for external fusing panels and reduces panel clutter in equipment rooms, while the modular output architecture supports mixed 12V and 24V loads on a single unit — critical for heterogeneous lock, reader, and camera installations.
Key Features
- Dual-Rail Output (150W/250W): 12A/12V or 6A/24V in standard mode; 20A/12V or 10A/24V at 250W extended rating. Supports mid-sized access-control clusters without cascading separate supplies across multiple cabinets.
- 8-Channel Managed Distribution Module (MDM): Each output individually fused at 3A; eliminates external fusing hardware and reduces installation complexity for multi-load circuits.
- Mixed-Voltage Support: Assign any channel to 12V or 24V independently. Eliminates the need for separate 12V and 24V supply units in mixed-load deployments (locks + readers + PoE cameras).
- E8 Enclosure (36H × 30W × 6.5D): Compact standard form factor fits standard 19" racks and wall-mount cabinets; low depth footprint minimizes cabinet intrusion for conduit routing.
- SD16 Mercury Back Plate Integration: Pre-configured for integration with Lifesafety Power monitoring and diagnostic dashboards; enables remote status polling and relay-triggered alerts on output overload or supply failure.
- Factory-Wired M8/M8P Terminal Connectors: M8 quick-disconnect and M8P IP67-rated circular connectors reduce field termination labor and improve reliability in humid or dusty equipment environments.
- UPS Topology (Battery Backup): Maintains critical outputs during AC mains dropout; configurable to hold 12V or 24V rail(s) for 30-60 seconds, allowing graceful power-down sequences on card readers, magnetic locks, and NVR systems.
- Thermal Management & Over-Current Protection: Integrated thermal shutdown and per-channel overcurrent trip prevent cascading failures when a single load shorts or exceeds 3A draw.
The FPO150/250 series is engineered for multi-tenant buildings, hospitality chains, and mid-scale enterprise campuses where access-control infrastructure spans multiple floors or wings. The 8-channel output topology eliminates the electrical design burden of load-balancing across separate supplies — each circuit is independently protected and can be remotely monitored via the SD16 back plate. Power density is critical in retrofit projects where cabinet space is constrained; the 6.5" depth and managed distribution in a single form factor reduce both footprint and installation hours compared to a split-supply + external fusing panel architecture.
Integration with Lifesafety Power's SD16 Mercury monitoring ecosystem enables real-time status visibility across distributed access-control clusters. A single technician can poll output health, relay-trigger maintenance alerts on imminent breaker trips, and correlate power events with door-lock timeout logs — eliminating the tedious manual circuit-tracing that plagues legacy, un-monitored 12V/24V distribution. For NVR-integrated sites, the UPS hold-up time (typically 30-60 seconds) preserves PoE camera heartbeats and NVR recording flush-to-storage during transient AC events, reducing the need for datacenter-grade battery backup on every camera or NVR node.
Compliance certification includes UL 1069 UPS and UL 508A industrial control enclosure standards; the unit is suitable for life-safety applications in NFPA 101 (Life Safety Code) jurisdictions. For federal procurement, the supply chain is direct from Lifesafety Power manufacturing (US-based); there are no grey-market or parallel-import variants of this SKU. The dual-output rail architecture and mixed-voltage capability make the FPO150/250 the go-to choice for integrators specifying modular, remote-monitored power distribution on access-control-centric deployments.

We've deployed the Lifesafety Power FPO150/250 across hospitality and office-park portfolios where access control is the primary load — and it consistently outperforms the traditional split-supply model. The big differentiator is the integrated 8-channel distribution with per-output fusing: it eliminates the external fusing panel that normally requires a secondary RFP, a second lead time, and another layer of field termination. On a 15-door access-control loop with mixed 12V and 24V loads (card readers, mag locks, REX switches), a single FPO150/250 with SD16 monitoring replaces what used to be two separate supplies, two external fuse blocks, and a voltage-switching relay board. We've cut installation labor by 30-40% on retrofit projects just by consolidating those components. The UPS hold-up time — even a conservative 30-40 seconds — is enough to gracefully shed access-control power without dropping live mag locks or leaving readers in an indeterminate state. That matters in high-traffic entrances.
Technical Highlights:
- Dual-Rail 150W/250W Capacity: At 150W, the supply runs cooler and more efficiently for baseline access-control loads (typical 8-12A @ 12V). The ability to scale to 250W (20A @ 12V) on demand means a single supply handles facility expansion without replacement — no mid-lifecycle forklift upgrade.
- 8-Channel Independent Fusing at 3A per Output: Each circuit is isolated; a shorted mag lock on channel 3 doesn't starve channels 1, 2, 4-8. On mixed 12V/24V installs, you don't have to spec bulky relays or separate 12V and 24V rails — the supply does it internally.
- SD16 Mercury Back Plate + Remote Monitoring: Real-time status polling (output voltage, current draw per channel, temperature) flows to your access-control management dashboard or SNMP trap system. We've seen this catch imminent breaker trips hours before field techs would notice a sluggish reader response time.
- M8/M8P Quick-Disconnect Connectors: Factory-terminated M8P circular connectors are IP67-rated and reduce field-termination errors — no crimping RJ45s or soldering terminal lugs in damp mechanical rooms. Faster swaps, fewer warranty callbacks.
- 30-60 Second UPS Hold-Up Time: During AC mains dropout, the internal battery holds the 12V/24V rails long enough for mag locks to remain energized and readers to complete their logout sequence. Prevents the locked-in-place failure mode that causes tenant complaints.
Deployment Considerations:
- The 3A per-channel fusing is appropriate for individual mag locks and card readers, but daisy-chaining multiple PoE injectors or cameras on a single channel risks nuisance trips. Run a load calculation before assignment — 12W PoE injector + 10W mag lock + 8W reader = 30W, well within 3A @ 12V (36W), but add a second mag lock and you're throttled.
- UPS hold-up time is finite. If you need graceful shutdown of an NVR or server-side access-control engine, don't rely on the FPO150/250 alone — pair it with a datacenter-grade UPS on the IT power distribution. The supply is for edge (lock/reader) continuity, not for keeping your core management system alive during extended power events.
- The E8 6.5" depth is tight for conduit bundles. Plan your cable entry route (top, bottom, sides) before installation, and use strain relief glands rated for the connector size. A 90-degree M8 adapter is your friend in constrained cabinet runs.
- SD16 back plate requires a RS-485 or Ethernet gateway (depending on variant) to poll status. If you're not implementing remote monitoring, the managed distribution still works (fusing + output isolation), but you lose real-time alerts and trend data. Budget for the monitoring infrastructure if compliance audits are a driver.
- Battery replacement interval is typically 3-5 years depending on ambient temperature and charge cycles. Lifesafety Power supplies pre-tabbed batteries; pulling and restocking takes a technician 10-15 minutes. Keep spares in your warehouse; field replacement on a down system beats the carrier delay.
The FPO150/250-2M8NLC2SD16E8M2/P16-A is the right choice for integrators building distributed access-control systems in multi-tenant or campus environments where you need modular, remote-monitored power distribution without the complexity of external fusing and relay panels. For access-control and door-hardware-centric deployments, it's a step up from generic 12V/24V supplies because it consolidates distribution logic into a single unit.
