Lifesafety Power FPO150/250-2C82D8NLCE8M2 Dual-Output Power Supply with Relay Lock Control
The Lifesafety Power FPO150/250-2C82D8NLCE8M2 is a configurable power supply designed to centralize power distribution and door control logic in access control and video surveillance installations. It delivers either 150W at 12A/12V or 6A/24V, or scales to 250W at 20A/12V or 10A/24V — meaning you can right-size output voltage and current based on your lock hardware and auxiliary load without swapping units. The E8 enclosure (36H x 30W x 6.5D inches) mounts in standard equipment racks or wall cabinets, keeping power and relay control consolidated and documented in one place.
Key Features
- Dual Power Rating (150W / 250W): The FPO150/250 supports both 150W and 250W operation; you select the output wattage that matches your system load. This flexibility means a single platform handles everything from smaller access-control retrofits (150W) to multi-door deployments (250W) without requiring different SKUs in inventory.
- Selectable 12V or 24V Output: Lock solenoids, power supplies for IP cameras, and auxiliary devices vary in voltage requirement. The ability to configure the supply for either 12VDC or 24VDC at rated current eliminates the need for separate converters or multiple units, reducing rack clutter and simplifying service documentation.
- 8 Relay Lock Control Outputs (3A Fused): Each relay output is individually fused at 3A and selectable for FAI (fail-as-is), failsafe, or failsecure mode — critical for access control logic where a power loss must trigger a defined state (unlocked or locked) rather than leaving the system indeterminate. No external relay module required.
- 8 DC Auxiliary Outputs (3A Fused): Beyond lock control, the FPO150/250 provides 8 additional 3A outputs, each assignable to Bus1 or Bus2. These drive indicator lights, sensors, or secondary devices, keeping all power distribution under one management point and reducing point-of-failure risk across distributed cabinets.
- Compact E8 Enclosure: At 36" H × 30" W × 6.5" D, the unit fits standard 19" rack rails and wall-mount frames, making it suitable for server rooms, telecom closets, and equipment shelves without oversized footprint penalties. The fused, labeled outputs are field-accessible from the front, reducing troubleshooting time.
- Supervision and Fault Reporting: Integration with access control panels via standard low-voltage data buses allows the supply to report fuse status, voltage anomalies, and output state back to a central controller, enabling proactive maintenance before a load device fails.
Integration & Compatibility
The FPO150/250-2C82D8NLCE8M2 integrates with any access control system that requires centralized, supervised power and relay logic — from access control power supplies to access control system architecture deployments. The configurable failsafe/failsecure modes meet NFPA 101 Life Safety Code requirements for emergency egress, a non-negotiable factor in commercial and institutional projects. Relay outputs are compatible with standard electromagnetic and electronic lock actuators (12V or 24V solenoids, strike plates, magnetic locks). The auxiliary outputs support 24V PIR sensors, door position switches, and indicator strobes without additional power conditioning.
When to Choose a Different Model
If your system requires more than 8 relay outputs, or if you need integrated UPS (battery backup) capability for continuous access during power loss, examine higher-capacity variants or dedicated battery supervision modules within the Lifesafety Power product line. If you require PoE power injection for IP cameras alongside access control, a hybrid PoE+ switch may be more efficient than combining this supply with a separate injector.
Frequently Asked Questions
Q: Can I operate the FPO150/250 at both 150W and 250W output simultaneously?
A: No. The unit is configured for either 150W or 250W operation at installation — not both. Select the rating that matches your maximum combined load (relay and auxiliary current draw). Once set, it remains fixed unless reconfigured.
Q: What happens to the lock relays if power fails?
A: The relay mode (failsafe, failsecure, or fail-as-is) determines the outcome. Failsafe relays de-energize and unlock when AC power is lost — standard for emergency egress. Failsecure relays remain locked until power returns. Consult your local fire code and building authority to confirm which mode is required.
Q: Is battery backup included?
A: No. The FPO150/250 is an AC-powered supply. If you require 4-8 hours of backup lock operation during power loss, a separate 24V DC battery module and charger circuit must be added downstream or integrated into an external UPS system.
Q: What kind of supervision data does the supply report?
A: Fuse status for each relay and auxiliary output, input voltage monitoring, and bus fault detection can be wired to an access control panel's input terminals or monitored via a data bus connection (depending on the panel's capabilities). Confirm bus protocol compatibility with your controller before integration.
Q: Can I mix 12V and 24V outputs in the same unit?
A: No. The FPO150/250 is configured for a single output voltage (either 12V or 24V) at the time of installation. If your system requires both, you must deploy two separate units or use intermediate voltage converters.
Q: What's the maximum current per relay or auxiliary output?
A: Each relay and auxiliary output is fused at 3A. Do not exceed 3A per output; loads drawing more current will immediately blow the fuse and de-energize that circuit. Plan your lock and device load accordingly.
The Lifesafety Power FPO150/250-2C82D8NLCE8M2 solves a real integration headache: centralizing access control power and relay logic without forcing you to choose between 12V and 24V, or between 150W and 250W capacity. Most integrators I work with install this unit when they're managing three or more doors in a single building zone and want to avoid spraying separate 12V/24V supplies across multiple cabinets. The individually fused relay and auxiliary outputs mean a shorted lock solenoid won't take down your whole system — only that output trips.
Technical Highlights:
- Dual Power Rating (150W / 250W) with Selectable 12V/24V Output: Avoids inventory proliferation. You configure this unit once for your site voltage and load, and it handles both small retrofits (150W) and larger door banks (250W) without a SKU change. The 12V or 24V selection maps directly to your lock solenoid standard, eliminating awkward converters.
- 8 Relay Lock Outputs at 3A Each, Per-Output Failsafe/Failsecure Selection: This is where the FPO150/250 earns its cost. Each relay independently selects FAI, failsafe, or failsecure — meaning one door can unlock on power loss (emergency egress) while another stays locked (secure zone). Standard fail-as-is setups can't do this without external logic; here it's built in.
- 8 Fused Auxiliary Outputs Assignable to Bus1/Bus2: Beyond lock control, you get auxiliary power and bus switching for sensors, strobes, and indicators. The Bus1/Bus2 assignment lets you segment loads for controlled shutdown or priority power management during UPS handoff — a feature most commodity supplies omit.
Deployment Considerations:
- Failsafe/Failsecure Mode Must Be Pre-Planned: There's no field-selectable jumper or software toggle on the relay outputs — each output's fail mode is typically set at the factory or via internal DIP switches (check your configuration sheet). If you misjudge your egress requirement and set a high-security door to failsafe when it should be failsecure, you'll need to ship the unit back or live with a significant security gap. Validate with your AHJ (authority having jurisdiction) before ordering.
- No Battery Backup Onboard: The FPO150/250 is pure AC-powered logic. If a power loss must sustain lock operation for more than a few seconds, budget for an external 24V DC battery module and charger, or integrate this supply downstream of a larger UPS. Many integrators forget this and then scramble when the site power flickers.
- 3A Per-Output Ceiling Is Real: Don't try to gang outputs or exceed 3A per relay/auxiliary. A single high-current solenoid (e.g., a fail-safe electromagnetic lock rated for 5A hold current) will immediately pop the fuse. Pre-size your loads and fuse accordingly — no tricks.
The FPO150/250-2C82D8NLCE8M2 shines in mid-scale institutional or commercial access control where you have 3–8 doors across one or two floors, unified voltage requirements, and you need local supervision and failsafe logic without a PLC or controller. For single-door retrofits, it's overkill; for campus-wide systems, you'll want a networked control platform. But for that sweet spot — a bank branch, clinic, or office tower floor — this unit eliminates a lot of wiring and external relay modules.
