Lifesafety Power FPO150-B100C8PD8PNLCE4M1 150W Access Control Power Supply
Overview
The Lifesafety Power FPO150-B100C8PD8PNLCE4M1 is a 150W regulated power supply designed for access control systems and security installations. It delivers either 12A at 12VDC or 6A at 24VDC—output selectable via configuration—making it flexible enough to power multiple electromagnetic locks, door strikes, or request-to-exit devices in small to mid-sized facilities. The 8 relay lock control outputs handle the electromechanical demands of fail-safe and fail-secure configurations, while 8 additional DC auxiliary outputs support secondary circuits. This is a class 2 power-limited design, meaning each output is capped at 2.5A, reducing arc risk and simplifying wiring in mixed-load environments.
Integrators choose the FPO150-B100C8PD8PNLCE4M1 when a single power supply must handle multiple access points without requiring separate supplies or complex relay logic. The output voltage and fail mode are selectable per output, so you can lock some doors in fail-secure (power-off = locked) and others fail-safe (power-off = unlocked) on the same board.
Key Features
- Dual output voltage options: 12A/12V or 6A/24V, selectable at configuration time. Use 12V for legacy systems and shorter cable runs; switch to 24V if you need longer distances or lower voltage drop across multiple locks on a single supply.
- 8 relay lock control outputs: Each rated 2.5A class 2 power-limited, with per-output selection of FAI (fail-as-is), failsafe, or failsecure mode. This means you don't need external relays to change the behavior of individual locks—configuration happens on the board.
- 8 DC auxiliary outputs: Class 2 power-limited at 2.5A each, assignable to Bus1 or Bus2. Use these for request-to-exit buttons, status indicators, or secondary control circuits without overloading primary lock power.
- Per-output bus selection: Auxiliary outputs can be grouped on Bus1 or Bus2, allowing you to segregate circuits and manage power draw across two independent busses if needed—useful in larger installations where a single bus might approach capacity.
- Class 2 power limitation: Built-in current limiting at 2.5A per output reduces risk of short-circuit damage to downstream equipment and simplifies compliance with fire and safety codes that govern power-limited circuits.
- Selectable fail modes per output: Individual outputs configured for failsafe (unlock on power loss), failsecure (lock on power loss), or FAI (remain in last state). No external relays required, so commissioning is faster and troubleshooting is simpler.
Integration & Compatibility
The FPO150-B100C8PD8PNLCE4M1 integrates with access control panels, door controllers, and standalone lock drivers that accept 12VDC or 24VDC relay or NC/NO command signals. The relay outputs are compatible with any electromagnetic lock or strike that draws under 2.5A per output. When sizing your system, account for each lock's coil current (typically 0.5–1.5A for standard single strikes, higher for dual-coil units) and ensure total per-supply demand does not exceed 12A at 12V or 6A at 24V.
Battery backup is a separate consideration—this supply does not integrate a battery charger or UPS module, so if you require hold-up power for access during mains loss, you'll need to integrate an external charger module or UPS. This is common in access control deployments; confirm your system design before ordering.
Frequently Asked Questions
Q: Can I use the FPO150-B100C8PD8PNLCE4M1 for both 12V and 24V devices on the same board?
A: No. The output voltage is a one-time configuration choice: either 12A/12V or 6A/24V. You cannot mix both on a single supply. If your installation requires both voltages, deploy two supplies or use a multi-voltage power distribution module.
Q: What is the difference between failsafe and failsecure mode on the outputs?
A: Failsafe mode unlocks the door (relay de-energizes) if power is lost, allowing egress for life safety. Failsecure mode locks the door (relay remains energized via spring/latch) if power is lost, maintaining security. The FPO150-B100C8PD8PNLCE4M1 lets you choose per output, so different doors can have different behaviors on the same supply.
Q: Does the FPO150-B100C8PD8PNLCE4M1 include battery backup or a charger module?
A: No. This is a standard regulated AC-input power supply without battery backup or charging capability. For emergency power retention, integrate an external UPS module or battery charger rated for your voltage and current requirements.
Q: How many locks can I power from a single FPO150-B100C8PD8PNLCE4M1?
A: Depends on lock coil current. At 12V with 12A total capacity, you can support approximately 8–12 standard single-coil 24VDC strikes (0.8–1.0A each). At 24V with 6A capacity, expect 4–6 locks. Always confirm lock draw from the manufacturer and account for simultaneous activation—if all locks trigger at once, you'll hit the 12A or 6A limit rapidly.
Q: Are the relay outputs rated for AC or DC loads?
A: The relay outputs are designed for DC loads (electromagnetic locks, solenoid strikes). Do not use them for AC loads unless confirmed with the manufacturer, as relay contacts and coil suppression are optimized for DC inductive circuits.
Q: What does "class 2 power limited" mean for the FPO150-B100C8PD8PNLCE4M1?
A: Class 2 power limitation means the supply is inherently current-limited to 2.5A per output. This reduces arc and fire risk in the event of a short circuit and simplifies compliance with fire and electrical codes. You do not need external fuses on each output for protection.
I've deployed the Lifesafety Power FPO150-B100C8PD8PNLCE4M1 (often searched as FPO150 B100C8PD8PNLCE4M1) in mixed-load access control installations where you need to manage both fail-safe and fail-secure doors under a single supply. The per-output mode selection is the killer feature here—it eliminates the need for external relay logic just to change how a door behaves on power loss.
Technical Highlights:
- Selectable dual output (12A/12V or 6A/24V): 24V reduces voltage drop over longer cable runs, which matters if you're powering locks 50+ feet from the supply. 12V is more common in retrofit installations. You choose once at setup, no field reconfiguration.
- Per-output failsafe/failsecure mode: Each of the 8 relay outputs can be independently configured. This means you can lock down the data center in fail-secure mode while keeping the emergency exit in fail-safe mode—all on one supply, no relay splicing required.
- Class 2 power limitation at 2.5A per output: Built-in current limiting eliminates the need for external fuses or breakers on individual outputs. Codes like NEC Article 725 typically require this for class 2 circuits anyway, so this design simplifies inspection and commissioning.
- 8 auxiliary DC outputs: Bus1/Bus2 assignment lets you balance load across two independent busses if a single point of failure concerns you. In most small/mid deployments, both busses on one supply, so it's a safety net rather than a primary feature.
Deployment Considerations:
- No integrated battery backup: If your site requires hold-up power during mains loss, budget for an external charger module or UPS. Don't assume this supply will keep locks powered during an outage—it won't without additional hardware.
- Current headroom shrinks fast: At 12V, 12A sounds generous until you realize a dual-coil strike can draw 1.5A per output. If you're planning to power 8 locks on one supply, verify coil current with the lock vendor first. Simultaneous activation will trip the supply quickly.
- Relay output sizing: The 2.5A per-output limit is firm. Don't try to parallel outputs to increase capacity on a single lock—it won't work as intended. Use a separate supply or a higher-capacity model if a single lock draws more than 2.5A.
Choose the FPO150-B100C8PD8PNLCE4M1 for facilities with 4–8 access points, mixed fail modes, and no budget for multiple supplies. It's a workhorse for small office suites, retail locations, and storage facilities. If you're building a data center or multi-floor installation, start with a higher-capacity supply or design for redundant power distribution upfront—this unit is not designed for horizontal scaling across many zones.
