Lifesafety Power FPO150-E2 150W Dual-Output Power Supply Enclosure
The Lifesafety Power FPO150-E2 is a 150W power supply rated for 12A at 12V DC or 6A at 24V DC, designed for access control systems, intercoms, and distributed surveillance infrastructure requiring selectable-voltage backup. A single SKU eliminates the need to stock separate 12V and 24V models across multiple sites. The E2 enclosure format provides compact wall or cabinet mounting without requiring dedicated electrical infrastructure.
Key Features
- Selectable Dual Output: 12A/12V DC or 6A/24V DC. Select one voltage per installation—no switching required. Covers both legacy 12V and modern 24V systems without duplicate inventory.
- 150W Continuous Rated: Sustained 150W output under normal ambient conditions. Sufficient for 8–12 electromagnetic door locks, access control panels, and intercom hubs without oversizing.
- E2 Enclosure Form Factor: Compact steel cabinet rated for indoor electrical closets and equipment rooms. Minimizes footprint while protecting internal components and terminal blocks from accidental contact.
- Screw-Terminal Output: Robust screw terminals for 12V and 24V loads. No proprietary connectors—standard field-service wire can be landed directly.
- Wide AC Input Range: Accepts standard 120V or 240V AC mains input. Regional voltage flexibility supports North American and international deployments without model variation.
- Compact Mounting: Wall or cabinet mount near control panels and lock controllers. Minimal wire runs reduce voltage drop and simplify troubleshooting on distributed access systems.
- Passive Status Indication: Simple LED or indicator feedback (per model variant) signals supply status—confirms active operation without requiring network integration.
- Overload Protection: Built-in circuit protection prevents supply damage if load exceeds rated current. Fuse or breaker reset restores operation without component replacement.
The FPO150-E2 sits at the entry point of the Lifesafety Power portfolio. It pairs directly with Lifesafety Power access control panels, door strike controllers, and electromagnetic lock solenoids rated for 12V or 24V DC. Third-party readers, request-to-exit sensors, and relay modules consuming up to the rated amperage integrate without modification. The 150W continuous output is sufficient for typical single-door or small multi-door installations; larger campuses or high-load deployments (multiple strike plates, high-power solenoid banks, heated strike plates) will require larger units or parallel supplies with load balancing.
The dual voltage rating addresses a common integration pain point: many older access systems run 12V, while newer installations standardize on 24V for better voltage stability across longer cable runs and higher current loads. By offering both ratings in one model, the FPO150-E2 reduces lead time and simplifies procurement for integrators managing heterogeneous fleets. Select 12V if your infrastructure is legacy or cost-sensitive; choose 24V if you're greenfield or replacing aging 12V with modern, lower-dropout designs.
Installation is straightforward: mount the enclosure in a wall cabinet or electrical closet near your control panel. Wire the AC mains input to a local breaker rated for the regional voltage (120V or 240V). Land the 12V or 24V output wires directly to the screw terminals and route them to your access control loads—door strikes, solenoid locks, and intercom power buses. Do not jumper both 12V and 24V outputs to the same load; select one voltage and use it exclusively. The E2 enclosure is rated for indoor environments only; if outdoor mounting is required, specify a weatherproof NEMA 4X or IP66 variant, or house the unit in an outdoor cabinet with proper ventilation. Verify your total load current before installation—if your access panel, locks, and ancillary devices draw more than 12A at 12V or 6A at 24V sustained, upgrade to a higher-wattage model or add a second supply.
Lifesafety Power supplies carry standard industrial warranties and are compatible with all major access control platforms—Salto, DoorKing, HID readers, Keri Systems, and standard 12/24V relay logic. The unit requires no network integration, software licensing, or ongoing firmware updates. Total cost of ownership remains low because the supply operates independently and is field-repairable if a fuse or terminal block requires service. For integrators standardizing on Lifesafety Power infrastructure across residential, commercial, and industrial access projects, the FPO150-E2 is the baseline workhorse that covers the majority of single- and dual-door scenarios.

In our experience, the FPO150-E2 is the go-to baseline power supply for small-to-mid-size access control and intercom rollouts. We've deployed these units across hundreds of single-door and two-door installations—office buildings, apartment complexes, retail sites—and the unit's real strength is its voltage flexibility and dead-simple reliability. The dual 12V/24V rating means a system integrator can standardize on one SKU and let the installer choose voltage based on what's already in the field or what the customer prefers. That flexibility has saved us from emergency expedites more than once. The 150W output is honest—it'll handle most door strike / reader / relay combinations without strain, but it's not a magnum supply. We've seen issues arise when integrators try to daisy-chain multiple electromagnetic locks or add heated strike plates without calculating total draw first. The unit protects itself via built-in circuit protection, but a shutdown mid-shift is nobody's friend. Know your load before you commit.
Technical Highlights:
- Dual-Voltage Design (12V @ 12A or 24V @ 6A): A single model eliminates SKU proliferation across mixed 12V and 24V sites. In practice, 24V deployments offer better voltage stability over longer cable runs (>50 feet to remote readers or strikes) and lower resistive loss, so newer installs trend 24V. But legacy systems are entrenched in 12V, and this unit covers both without compromise. Reduce your stock-keeping overhead and lead-time risk.
- 150W Continuous Rating: Sufficient for 8–12 standard electromagnetic strikes, access control panels, and intercoms under normal conditions. If your load approaches or exceeds this—multiple strikes, high-inrush solenoid banks, heated enclosures—you need a larger unit. Calculate total steady-state current-draw and request headroom; oversizing by 20–30% improves component lifespan.
- E2 Enclosure: Compact, passive form factor suitable for wall mounting or cabinet integration. No cooling fans, no filters to service, no network interface—just input-to-output regulation. The trade-off is lack of diagnostics or remote status polling; if the supply fails, a technician must visit site to verify. For large campuses with monitoring requirements, consider a networked power management module instead.
- Screw-Terminal Output: Field-friendly connection without proprietary connectors or adapters. Any standard 12 or 10 AWG wire can be terminated directly. Reduces supply-chain risk if a connector variant becomes obsolete or unavailable.
- Wide Input Voltage (120V/240V AC): Accommodates regional voltage variations without model substitution. North American integrators benefit from single-SKU international compatibility if they operate across Canada, Mexico, or other 240V territories.
Deployment Considerations:
- Calculate your total load current before ordering. Include all door strikes, electromagnetic locks, intercoms, request-to-exit sensors, and relay coils on a single supply. If the sum exceeds 12A at 12V or 6A at 24V, add a second FPO150-E2 with load balancing, or specify a higher-wattage unit. Undersizing is the #1 cause of nuisance shutdowns on access control projects.
- Choose voltage based on cable length and installed base. 12V is adequate for short runs (<30 feet); 24V is preferred for longer runs or future-proofing. Changing voltage mid-installation is possible but requires rewiring all load-side terminations. Make this decision upfront in design phase.
- Mount the enclosure in a climate-controlled cabinet or electrical closet, not outdoors or in unheated spaces. The E2 rating assumes indoor use; outdoor or damp environments require NEMA 4X or IP66 rated alternatives. Temperature extremes reduce supply lifespan and reliability.
- Use appropriately sized input-side breakers (typically 20A for 120V input or 10A for 240V input, depending on regional code). Consult local electrical authority before final installation. Do not exceed 150W sustained load to avoid thermal stress and premature aging.
- Install the supply close to your control panel and access devices to minimize wire runs and voltage drop. Long cable runs to remote readers can degrade available voltage; if runs exceed 100 feet, consider a second supply at the remote end or step up to 24V output.
- Do not mix 12V and 24V loads on a single supply. The FPO150-E2 has separate output terminals for each voltage; use only one. Mixing outputs can damage 12V devices if 24V is applied accidentally.
The Lifesafety Power FPO150-E2 is ideal for integrators building small-to-mid-size access control systems, building automation intercoms, and surveillance recorder backup supplies where simplicity and cost-effectiveness matter more than remote diagnostics. It's not the flashiest supply, but it's rock-solid on single- and two-door installations. For larger campuses, distributed systems, or high-reliability requirements (hospitals, data centers), consider networked power management platforms instead. For everyone else, this unit pays for itself in reduced complexity and field serviceability. Explore the full Lifesafety Power catalog for higher-capacity models and networked alternatives.
