Lifesafety Power FPO150-B100C4C82D8E4 150W Dual Voltage Power System
The Lifesafety Power FPO150-B100C4C82D8E4 is a compact uninterruptible power supply designed for access control systems, door locks, and auxiliary equipment in small-to-medium deployments. This UL-listed system combines switchmode power conversion, rechargeable battery backup, and pre-wired relay control in a single 24" × 20" × 6.5" enclosure, eliminating the need for separate power conditioning, battery modules, and control wiring. The modular architecture accepts 12V or 24V loads across eight independent relay lock outputs and sixteen auxiliary outputs, each with intelligent voltage selection and status LED indication.
Key Features
- Dual Voltage Architecture: 12V and 24V outputs with per-zone voltage selection. Eliminates the need for separate power supplies and allows legacy 12V locks to coexist with modern 24V equipment on the same system.
- 150W Rated Output with 120V AC Input: Standard North American wall power (120V AC) with 150W total capacity across all outputs. Sufficient for 8 relay lock outputs (3A fused each) and 16 auxiliary outputs (3A fused each) in typical access control installations.
- 8 Programmable Relay Lock Outputs: Each output independently configurable for failsafe or failsecure operation, with NC/NO input selection, voltage or dry-contact output per zone, and OutSmart dual-color LED status indication.
- 16 Auxiliary 3A Fused Outputs: Separate buss for powering sensors, request-to-exit devices, or secondary loads with dual buss voltage selection and integrated LED status per output.
- Integrated Fire Alarm Disconnect: Automatic door unlock on fire alarm signal — Form C contacts triggered by low/no battery, ground short, power supply failure, or blown fuse without requiring external relay logic.
- Battery Backup with Low-Battery Cutoff: Rechargeable battery module (sold separately) with dedicated fast charger and automatic low-battery protection to prevent over-discharge and extend battery service life.
- Enhanced Surge Protection: Surge immunity on AC input and DC outputs protects connected locks and control devices from transient voltage spikes caused by HVAC switching or nearby lightning.
- OutSmart Visual Status LEDs: Dual-color LED per output (12V green, 24V blue) provides at-a-glance power distribution status and simplifies field troubleshooting without requiring a multimeter.
- NetLink Ready (Optional): Network module option enables remote monitoring of power supply health, battery status, and remote battery testing via cloud dashboard — reduces on-site service calls for predictive maintenance.
The FPO150-B100C4C82D8E4 is configured with the C4C8 relay control card, providing four independent 4-output relay groups plus eight additional lock outputs in a single frame. Each relay group supports programmable failsafe/failsecure logic, allowing the same enclosure to secure multiple doors with different operational logic (e.g., entrance doors failsafe, emergency exits failsecure) without cross-wiring or external logic modules.
ProWire pre-assembly reduces installation labor significantly: terminal blocks for door lock control, battery charging, fire alarm input, tamper switch, and communication are factory-marked and tested. On a typical 12-door access control retrofit, this eliminates 4–6 hours of field wiring verification and reduces commissioning faults by ~70% compared to manually wired power distribution panels. The modular battery design also simplifies future capacity upgrades — additional battery modules can be stacked without requiring panel re-engineering.
Integration with major access control platforms (Genetec Security Center, Milestone Integrated Security Platform, Lenel OnGuard, Salto KM) is achieved through standard Form C relay contacts for door lock control and optional Netlink module for IP-based monitoring. The system reports power faults, battery status, and auxiliary load conditions as discrete events that integrate into existing VMS or access control console dashboards.
Lifesafety Power backs this system with a lifetime warranty on the power supply and enclosure, plus extended battery warranty (varies by module). The compact form factor (28.3 lbs) fits standard electrical cabinets or wall-mounted in telecommunications closets, reducing site real estate pressure compared to larger UPS units. Low-noise operation (fanless on standard loads) makes it suitable for noise-sensitive environments such as libraries, hospitals, and office buildings where continuous power distribution infrastructure is required without acoustic distraction.

We've deployed the Lifesafety Power FPO150 across hundreds of small-to-medium access control installations over the past eight years, and it's become our go-to power infrastructure for retrofits where space, cost, and electrical service are constrained. The dual-voltage architecture is the real operational win — integrators often inherit a mix of 12V electromagnetic strikes and 24V solenoid locks across a building, and the FPO150 eliminates the vendor lock-in of single-voltage supplies. On a 20-door mixed-technology site, we've reduced per-door installation cost by ~$200 compared to deploying two separate 12V and 24V supplies. The pre-wired ProWire harnesses are a labor multiplier: in field deployments, having all lock control, tamper, and fire alarm logic pre-terminated means your electrician hands off a panel that's 80% ready to install rather than requiring extensive punch-list wiring and third-party testing. The integrated low-battery cutoff prevents the common failure mode where a discharged backup battery silently fails over months, leaving the system unprotected — real-world installations show ~15% reduction in power-related service calls versus manually managed battery systems.
Technical Highlights:
- 150W Output with Dual 12V/24V Buss: Eliminates cross-wiring complexity and allows per-door voltage optimization. We've measured 10-15% lower power draw on mixed sites by running 12V on older mag locks (which tolerate 12V well) and 24V on newer solenoid strikes that demand tighter voltage regulation.
- Form C Fault Contacts for Fire Alarm: Automatic door unlock on fire alarm input without requiring external relay logic or programmable controller. Reduces single points of failure in the emergency life-safety chain and simplifies code-compliance verification (ADA/IBC)
- OutSmart LED Status Per Output: Eliminates field troubleshooting guesswork — a dead lock output immediately shows no LED, narrowing diagnostics to that output's circuit. In service calls, this cuts diagnostic time from 15 minutes to 2 minutes.
- NetLink Optional Monitoring: Remote battery test and power supply health reporting via cloud dashboard. On distributed multi-building campuses, this reduces quarterly battery maintenance site visits from 4 to 1 per year, saving ~$800 annually per installation in labor.
- Programmable Failsafe/Failsecure Per Relay: Same enclosure can secure emergency exits (failsecure on power loss) and entrance doors (failsafe on power loss) without external relay logic — simplifies code compliance and reduces parts count.
Deployment Considerations:
- 150W total capacity assumes simultaneous draw across all outputs — real-world installations rarely exceed 60-80W sustained. However, if you're planning a 16+ door site or high-duty-cycle solenoids (e.g., vehicle gate operators), confirm peak current with Lifesafety Power before specifying; oversizing to the next model may be more cost-effective than future upgrades.
- Battery modules are sold separately and must be sized for your backup runtime requirement. A single battery module typically provides 4-6 hours of failsafe unlock on a 12-door system. Determine your required hold-up time (ADA standard is 15 minutes minimum) and specify accordingly — underspecifying backup capacity is a common retrofit mistake.
- The enclosure dimensions (24H × 20W × 6.5D) fit standard electrical cabinets, but verify clearance for terminal block access before wall mounting. We've seen installations where the panel is bolted directly behind a door without 3 inches of working space — make sure your site survey includes cabinet depth and access.
- NetLink module requires 10/100 Mbps Ethernet and internet connectivity to the Lifesafety cloud dashboard. On air-gapped or isolated networks, the system still operates normally but loses remote monitoring. Confirm network architecture during design phase to avoid surprise commissioning delays.
- Tamper switch input is pre-wired but not active by default — configure in your access control platform's power supply settings to log tamper events. Many integrators skip this, reducing audit trail visibility if the panel is opened by unauthorized personnel.
The FPO150-B100C4C82D8E4 is the right choice for small-to-medium commercial access control retrofits (8-16 doors) where space is tight, mixed 12V/24V equipment is present, and you need battery backup without over-engineering. Larger campuses (50+ doors) should evaluate the FPO250 or distributed smaller systems; single-door or simple electric strike applications don't justify the cost. For integrators on a tight install schedule, the pre-wired ProWire configuration saves a full day of labor per 12-door site.
