Altronix PDS8 8-Output 12VDC Power Distribution Module
The Altronix PDS8 is an 8-output 12VDC power distribution module designed to centralize power delivery across multiple security devices in access control, surveillance, and integrated security deployments. By accepting power input via PoE, the PDS8 eliminates the need for dedicated AC power infrastructure at the distribution point — a real cost and complexity reduction in retrofit installations or locations where AC wiring is difficult or expensive. Each of the eight independent 12VDC outputs supports separate devices, meaning you can power eight card readers, eight door strikes, eight auxiliary sensors, or any combination without managing eight separate power supplies.
Key Features
- 8 Independent 12VDC Outputs: Each output is isolated, so a short or fault on one channel doesn't cascade to the others. This matters in multi-reader access control systems where a single failed reader shouldn't take down the entire access point.
- PoE-Powered Input: Draws power from standard PoE infrastructure (the same Ethernet backbone feeding your IP cameras and access controllers). Eliminates the need to run separate 12VDC power lines to each distribution point, reducing installation labor and conduit runs.
- Fire Alarm Disconnect Capability: Meets life-safety code requirements in jurisdictions where power must be cut to ancillary security devices during a fire alarm event. Mandatory in many commercial deployments; verify your local authority having jurisdiction (AHJ) requirements before specifying.
- Compact Form Factor: Sized to mount inside cabinet enclosures, wall boxes, or secured junction points without consuming excessive rack or panel real estate. Reduces visible footprint in finished spaces.
- Lifetime Limited Warranty: Covers defects in materials and workmanship for the life of the product under normal use. Standard for Altronix power infrastructure; register with the manufacturer for fastest claims processing.
Integration & Compatibility
The PDS8 integrates into any access control or security infrastructure environment where 12VDC is the standard. It pairs naturally with Altronix controllers, card readers, electronic locks, and auxiliary sensors. In PoE-based surveillance and security systems, the PDS8 attaches to the same Ethernet backbone as your cameras and network devices, simplifying cabling and reducing single points of failure. Because it draws power via PoE rather than dedicated AC, it's well-suited to deployments where power redundancy is important — you can stack multiple PoE sources (injectors, powered switches) to feed the PDS8 on separate circuits.
Verify that your PoE power source (switch port or injector) has sufficient budget to feed the PDS8 plus all downstream loads. A fully loaded PDS8 delivering 12VDC to eight devices can draw significant current; consult the PoE power planning guide to confirm your switch or injector capacity.
When to Choose a Different Model
If you need more than eight outputs, or if your devices operate at voltages other than 12VDC (e.g., 24VDC, mixed voltages), evaluate other members of the Altronix power distribution family. If AC-powered distribution is acceptable and you don't have PoE infrastructure in place, a traditional wall-mounted power supply may be simpler and lower cost. If you require integrated surge protection or status monitoring beyond basic power delivery, consider enhanced models with built-in telemetry or environmental sensors.
Deployment Considerations
The fire alarm disconnect feature is a compliance plus, but it requires proper configuration and periodic testing. If your system uses fire alarm integration, confirm that the disconnect wiring and logic align with your alarm panel's output specifications. Mount the PDS8 in a location where it won't be blocked by conduit or equipment, and ensure adequate ventilation if it will be enclosed. Because it's powered via PoE, its availability is directly tied to your PoE infrastructure — any outage or misconfiguration upstream will cut power to all eight outputs.
Frequently Asked Questions
Q: Does the Altronix PDS8 require a separate 12VDC power supply?
A: No. The PDS8 is powered via PoE (Power over Ethernet) input. It converts PoE to regulated 12VDC on its output channels, eliminating the need for a separate power supply as long as your PoE source has adequate wattage.
Q: What happens if I overload one of the 8 outputs on the PDS8?
A: Each output is independently isolated. If one output experiences a short circuit or draws excessive current, that output will likely fail or be protected by overcurrent circuitry, but the other seven outputs should remain unaffected — critical for systems where loss of a single reader shouldn't take down access to all doors.
Q: Can the PDS8 power eight door strikes simultaneously?
A: Yes, provided your upstream PoE source has enough wattage to supply the total current. Door strikes typically draw 0.5–1.0A each when energized. Calculate total demand and confirm your PoE switch or injector can handle it; undersizing leads to voltage sag and unreliable operation.
Q: Is the fire alarm disconnect wired by the installer?
A: Yes. The fire alarm disconnect must be integrated into your fire alarm panel or relay circuit during installation. This is not a plug-and-play feature — consult your fire alarm contractor and local building code to ensure proper wiring and testing.
Q: What is the warranty period for the PDS8?
A: Lifetime Limited Warranty covering defects in materials and workmanship under normal use. Register the product with the manufacturer for fastest claims support.
Q: Does the PDS8 work with 24VDC devices?
A: No. The PDS8 outputs only 12VDC. If you require 24VDC distribution, evaluate other models in the Altronix power infrastructure lineup designed for that voltage.

The Altronix PDS8 is a purposeful power infrastructure device: it consolidates eight independent 12VDC outputs into a single PoE-fed module, eliminating the clutter of multiple power supplies and reducing wiring labor on access control and surveillance builds. The PoE input is the real differentiator — it means you're powering ancillary security devices (card readers, door strikes, sensors) from the same Ethernet backbone that feeds your cameras and network controllers, not running separate power conduit to each floor or cabinet.
Technical Highlights:
- Independent 12VDC Outputs: Isolation between channels means a fault on one reader or strike doesn't ripple across all eight. In multi-door deployments, this translates to localized failures rather than system-wide outages — critical for maintaining partial access if one device fails.
- PoE Input Eliminates AC Wiring: Draws power via standard Ethernet, so you skip the cost and labor of running dedicated 12VDC or AC power lines to remote distribution points. Works particularly well in retrofit projects where adding new power infrastructure is costly or disruptive.
- Fire Alarm Disconnect: Built-in capability to cut power to all eight outputs during a fire event, meeting life-safety codes in commercial buildings. Requires proper integration with your fire alarm panel during commissioning — not automatic.
Deployment Considerations:
- Upstream PoE wattage is critical. Calculate the total current draw of all eight downstream devices and confirm your PoE switch port or injector has headroom. Underpowered PoE sources cause voltage sag and unreliable operation on door strikes and locks.
- Fire alarm disconnect wiring must be verified with your fire alarm contractor and local authority. This is not a default feature — it requires configuration and periodic functional testing to ensure compliance.
Position the PDS8 in multi-reader, multi-strike access control systems where consolidation reduces panel clutter and PoE-powered infrastructure is already in place. It's also solid for distributed surveillance deployments combining IP cameras (already PoE-fed) with 12VDC auxiliary devices like motion sensors or door contact switches. Skip this model if you need 24VDC outputs or more than eight channels.
