Lifesafety Power FPG100/200-2C83D8PE4M1/P16-A Universal input 100

We've spent more time troubleshooting access control power infrastructure than we'd like to admit. The FPG100/200 shows up repeatedly on retrofit and remote-site specs because it consolidates three pain points: (1) distributed 24V power without running a massive cable bundle from a central supply, (2) local solenoid switching that doesn't require a networked controller to arbitrate failsafe logic, and (3) segregated auxiliary power that keeps reader supply isolated from the lock coil surge. On a 20-door office retrofit where running new power to each zone is prohibitive, this unit becomes the compact decision node that frees the installer from daisy-chaining 18/2 from a closet three floors away. Failsafe mode is non-negotiable for emergency egress doors in most jurisdictions—building code won't accept a solenoid that requires a powered relay to unlock. The per-output selectability is what differentiates this supply from generic 24V regulators. You get full fail-mode control without a separate relay bank.

Technical Highlights:

• 200W @ 24V Continuous Duty: 8A nominal output is a practical sweet spot for 4 simultaneous solenoid strikes (2A nominal draw per 24V strike) plus reader power. Avoid attempting 6+ simultaneous activations; thermal shutdown engages around 10A sustained. Know your lock duty cycle and the load profile before specifying.
• Per-Output Failsafe/Failsecure Selectability: Hardware jumper or relay configuration allows each of the 8 outputs to operate independently in fail mode. This is what code requires for emergency egress—critical in fire-rated stairwell doors and exits. Non-configurable supplies force you to add external relay logic.
• Dual Bus Architecture (Bus1 / Bus2): Auxiliary outputs can be assigned to separate bus rails, allowing priority-based load distribution. Pair this with a timer relay (external module) to enforce reader-first power sequencing if Bus voltage sags—readers respond before solenoids energize.
• 3A Fuse Per Relay Output: Protects against solenoid shorts without pulling the entire supply offline. A shorted strike doesn't cascade to the adjacent locks—the affected fuse opens, and the other 7 outputs remain live. Typical unmanaged 24V supplies fail-short on the first solenoid fault.
• Universal 85–264V AC Input: Handles voltage sag and phase issues common in rural or generator-backed sites. No step-down or UPS conditioning required. Pairs well with genset installations where utility power is unstable.
• Class 2 Auxiliary Output Power Limiting: 2.5A per auxiliary output ensures compliance with low-voltage wiring codes (NEC Article 725) — readers and buttons can share conduit with access control data cables without special insulation.

Deployment Considerations:

• Verify solenoid coil voltage (12V or 24V) against the supply output mode. A 12V lock won't activate reliably on a 24V supply, and a 24V coil will be under-energized and sluggish on 12V. This mismatch is the #1 field complaint—confirm wiring diagrams before crimping connectors.
• The 8A @ 24V output assumes a single supply. If you're daisy-chaining multiple FPGs for a larger cluster, ensure each has independent 85–264V AC feed. A single breaker feeding two supplies in parallel is not recommended without load-sharing logic.
• Failsafe mode requires power interruption to de-energize and release the lock. If mains power is interrupted but your 24V aux feed from an UPS remains live, the solenoid will remain energized. This is correct behavior for failsafe egress locks—the intent is that power loss releases the lock. But it means a prolonged power event can mask a solenoid short until power is restored. Test failsafe circuits under controlled power-loss conditions before final inspection.
• DIN-rail enclosure mounting is standard. Leave adequate ventilation (4+ inches clear above/below) to prevent thermal shutdown in high-ambient or stacked installations. A 200W supply in an unventilated cabinet can throttle to 150W continuous if ambient exceeds 40°C.
• Relay outputs are nominally 12V/24V dry contacts—they do NOT source significant current themselves. Solenoid coils must be wired across the relay common and the relay NO (normally open) contact. A common wiring error is connecting the solenoid in series with the relay coil—this will not activate the lock and will eventually open the relay coil itself.
• The auxiliary bus segregation (Bus1 vs. Bus2) is only meaningful if you're using external timer or sequencing logic. A simple feeder supply will see both buses at the same voltage. If you need true power-budget isolation, route Bus1 and Bus2 through separate 5A breakers in your control cabinet.

This is the go-to supply for secondary or remote door clusters that cannot justify a standalone IP access controller and UPS cabinet. Hotels, office parks, and educational buildings with distributed entry points rely on units like this to keep solenoid logic local and failsafe logic code-compliant. Integrators should familiarize themselves with the per-output jumper configuration and test failsafe sequencing before handoff.
