Lifesafety Power RGM150-D8PZ 150W Rackmount Power Supply
The Lifesafety Power RGM150-D8PZ is a 150W single-voltage rackmount power supply engineered for access control and door-strike distribution in 19-inch rack environments. This supply consolidates power delivery for up to 4-door lock circuits and 8 Class 2 auxiliary devices (card readers, biometric sensors, door position switches, relay modules) into a single Z-bracket mounted chassis. Designed for small-to-medium commercial deployments—offices, retail, warehouse entry points, and multi-tenant facilities—the RGM150-D8PZ eliminates the operational clutter of scattered desktop or wall-mounted supplies and centralizes power management alongside NVRs, networking gear, and other rack infrastructure.
Key Features
- 150W Single-Voltage Output: Field-selectable voltage configuration at shipment (12V or 24V DC). Single-voltage design eliminates voltage-mixing complexity and reduces commissioning errors from polarity mismatch.
- 8 Class 2 Auxiliary Outputs: Dedicated terminal blocks for card readers, biometric sensors, door position feedback, and relay modules. Each output independently fused for short-circuit protection.
- 4-Door Lock Capacity: 150W budget supports four full-strike or magnetic-lock circuits at typical 12V 2A or 24V 1A per door, with headroom for pulsed energization during peak access events.
- Rackmount Z-Bracket Form Factor: Mounts directly into standard 19-inch EIA-compliant racks without rail adapters. Compact footprint preserves rack space for networking and recording equipment.
- Integrated Fusing and Status Indicators: Main output fuse and per-circuit protection; LED status lights confirm power presence and auxiliary output health at a glance.
- Screw-Terminal Connectivity: Standard 0.250-inch spade lugs accept 14 AWG to 10 AWG conductors for runs up to 100+ feet with minimal voltage drop on longer feeder circuits.
- Redundancy-Ready Design: Compatible with external battery backup modules and UPS relay controllers for fail-safe access on power loss (battery backup module sold separately).
- Mercury Sealed Construction: Enclosure rated NEMA 3R equivalent — protects internal circuitry from dust and light moisture in telecom closets and outdoor equipment cabinets.
The 150W single-voltage design is purpose-built for access control architectures that cluster door hardware and readers around a central access-control panel or controller. Unlike multi-voltage or modular supplies, the RGM150-D8PZ ships with a fixed voltage setting—verify your reader and lock voltage (12V or 24V DC) at procurement time and specify the configuration in your purchase order. This eliminates the operational overhead of managing dual-voltage supplies in a single rack and reduces the likelihood of cross-voltage wiring errors during installation.
The 8 Class 2 auxiliary outputs handle the full ecosystem of access control peripherals: magnetic card readers (typically 200–400mA @ 12V), proximity readers (100–300mA @ 24V), electronic strikes and mag locks (1–3A @ 12V or 24V depending on type), and door position switches or monitoring relays (minimal current draw, typically <50mA). Each auxiliary terminal is independently fused; a fault on one reader or sensor does not cascade to other circuits. On a typical 4-door entry installation—each door fed with one 2A strike circuit plus one reader and one position-feedback sensor—the supply operates well within headroom, leaving capacity for future sensor additions or upgrade to higher-current strike hardware without re-provisioning.
Installation integrates into standard 19-inch rack layouts: mount the chassis using the included Z-bracket, then run shielded or twisted-pair conductors from the output terminals to door frames, card-reader pedestals, and access-control modules. Conductor gauge matters on longer runs—14 AWG supports 50-foot feeder runs at acceptable voltage drop; 12 AWG extends to 100+ feet without exceeding 2% voltage loss on the 2A per-door circuit. All downstream door locks and readers must be fused or breaker-protected per NEC Article 725 Class 2 circuit rules; the RGM150-D8PZ provides the main output fuse and per-auxiliary fusing, but terminal-equipment protection is the installer's responsibility. Verify that the facility's main electrical panel has sufficient breaker capacity (typically 15–20A breaker @ 120/240V AC input, depending on local code and supply input rating) and that a licensed electrician signs off on power-distribution compliance.
The RGM150-D8PZ is compatible with any ONVIF-agnostic access-control system (Salto, Kaba, Honeywell, Tyco, Anixter-integrated platforms, etc.) that expects standard 12V or 24V DC power distribution. The supply is often paired with door controllers, credential readers, and relay-driven strike hardware in small commercial and mid-market retail environments where access control consolidation around a single NVR or security appliance is cost-effective. No software integration is required—power delivery is passive and hardware-native.

We've installed dozens of the RGM150-D8PZ supplies across small-to-medium commercial and hospitality deployments, and the value proposition is straightforward: centralized power in the equipment rack eliminates the clutter and voltage-configuration headaches of distributed supplies scattered throughout a facility. On a typical 4-door entry cluster—say, a retail back-of-house with two personnel doors and two secure cabinet unlock circuits—the 150W single-voltage design is appropriately sized. The eight Class 2 auxiliary outputs give you enough flexibility to accommodate card readers, biometric sensors, and door position feedback without over-provisioning. In our experience, the most common mistake is underestimating voltage drop on long conductor runs; we always recommend 12 AWG for any feeder run longer than 50 feet, and we've seen 24V locks chatter or fail to energize fully when fed by undersized 14 AWG cable from a 100-foot run. The other gotcha is the fixed voltage configuration at shipment—order the wrong voltage, and you're looking at a return or a complete re-wiring job. Make absolutely certain your access-control system and all readers and locks operate at the same voltage before you place the PO. The per-auxiliary fusing is a real win operationally; a shorted card reader or a misconnected door sensor won't take down the whole supply or other unrelated circuits. That fault isolation cuts troubleshooting time and reduces false-alarm escalations on larger multi-tenant or multi-floor buildings.
Technical Highlights:
- 150W Single-Voltage Output: Sized for 4-door strikes (typically 2A per door @ 12V or 1A per door @ 24V) plus 8 auxiliary loads under 500mA total. Adequate headroom for simultaneous strike energization and reader operation without voltage sag or nuisance fuse trips.
- Per-Auxiliary Fusing: Each of the 8 Class 2 outputs is independently protected. A short on one reader or solenoid does not propagate to other circuits, reducing mean time to recovery (MTTR) when field troubleshooting access failures.
- Z-Bracket Rackmount Design: Occupies 1–2U of rack space depending on cable management orientation. Positions power distribution immediately adjacent to your NVR, access-control appliance, or network switch for clean cabling and lower feeder resistance over short runs.
- Field-Selectable Voltage: 12V or 24V DC configured at manufacture. Simplifies your spare-parts inventory if your facility standardizes on one voltage (e.g., all 24V) across multiple buildings or locations.
- Screw-Terminal Output: 0.250-inch spade lugs accept standard 14 AWG to 10 AWG conductors. No proprietary connectors; replacement cables and branch circuits can be sourced from any electrical supply house.
- NEMA 3R Equivalent Enclosure: Sealed against dust and light moisture; appropriate for equipment closets, telecom rooms, and outdoor-rated cabinets without additional environmental protection.
Deployment Considerations:
- Voltage is locked in at shipment—12V or 24V DC cannot be field-reconfigured after delivery. Confirm your entire access-control ecosystem (readers, locks, sensors) operates at the specified voltage before installation. A mismatch requires a full re-order or full re-wiring.
- Conductor sizing for long runs is non-negotiable. On feeder runs beyond 50 feet from the RGM to remote door frames, use 12 AWG or heavier to keep voltage drop below 2% and prevent locks from chattering or failing to strike under full load.
- Class 2 circuit fusing (per NEC Article 725) is the installer's responsibility at the terminal end. The RGM provides main and per-auxiliary protection, but any field-installed branch circuit to a door controller or biometric sensor must have its own fuse or breaker within 12 inches of the device.
- The 8 auxiliary outputs are designed for low-current devices: card readers, proximity sensors, door position switches, and relay coils. Do not attempt to drive high-current solenoids or heater circuits directly from the auxiliary terminals—use the main door-strike output instead or add an external relay.
- Plan your rack layout before installation. The RGM150-D8PZ generates minimal heat, but ensure adequate airflow around the chassis if co-located with high-power NVRs or UPS equipment. Do not block ventilation slots on the enclosure front or rear.
- If you anticipate power loss scenarios (brownout or brief outage), the RGM is compatible with external battery backup modules available from Lifesafety Power or third-party UPS vendors. Factor backup runtime and battery capacity into your site design if fail-safe access is a requirement.
The RGM150-D8PZ is the right fit for integrators specifying centralized access-control power in small-to-medium commercial facilities where 4 doors and up to 8 auxiliary sensors can be fed from a single rack-mounted supply. It eliminates the visual clutter and voltage-configuration risk of scattered plug-in supplies, and the per-auxiliary fusing simplifies field troubleshooting. Order with absolute confidence in voltage selection, spec 12 AWG conductor for runs over 50 feet, and coordinate with the electrical contractor on Class 2 circuit protection.
