Code Blue SLNF0250 24V DC Power Supply
Overview
The Code Blue SLNF0250 is a 24V DC power supply engineered for surveillance and access control deployments where outdoor durability and reliable 12-24V DC output are non-negotiable. With IP68 environmental rating and PoE 802.3af compatibility, the SLNF0250 handles wet, dusty, and temperature-variable installations typical in perimeter security, loading dock monitoring, and remote gate automation. If you're running multiple 12-24V devices across scattered outdoor locations, this supply eliminates the need to run separate AC circuits to each node.
Key Features
- 24V DC Output: Delivers stable 24V DC power—the industry standard for outdoor solenoids, door strike mechanisms, and analog alarm signaling devices. No voltage sag under load means reliable operation across distributed cable runs, particularly important on installations longer than 200 feet where voltage drop becomes visible.
- PoE 802.3af Compatibility: Supports standard 802.3af PoE injection, allowing you to power PoE cameras or auxiliary devices from the same circuit. Eliminates separate injectors when the SLNF0250 is deployed near powered network infrastructure.
- IP68 Environmental Rating: Full dust and water immersion protection to 1 meter for 30 minutes—meaning rain, condensation, and washdown spray won't compromise the unit. Deploy it in outdoor cabinets, wall-mounted enclosures, or equipment rooms without secondary weatherproofing.
- Dual Voltage Input Range (12–24V DC): Accepts 12V or 24V DC input during production phases, providing flexibility in retrofits or hybrid deployments where legacy 12V devices coexist with 24V infrastructure. Simplifies inventory management when branch offices run mixed voltages.
- Bluetooth Connectivity: Enables wireless configuration and monitoring of power status without physical access to the unit—useful for remote pole-mounted or cabinet-mounted installations where you need real-time visibility into supply health without a site visit.
- Paging Amplifier Support: Integrated paging capability via 12-24V DC bus allows integration with analog speaker systems or tone-based alert signaling, common in older access control and alarm infrastructures. Bridges legacy audio systems to modern IP monitoring without replacing existing horn drivers.
Integration & Compatibility
The SLNF0250 integrates into any surveillance or access control architecture requiring stable 24V DC rails. Its PoE 802.3af profile makes it compatible with standard PoE switches and injectors—typical 48V PoE lines can be conditioned through the SLNF0250 to deliver 24V DC to door strikes, gate operators, and relay modules. Bluetooth control allows integration with mobile maintenance workflows, reducing the need for in-cabinet wiring diagnostics. The paging amplifier function connects directly to analog speaker buses, enabling voice alerts or tone signaling without separate audio infrastructure.

Frequently Asked Questions
Q: Is the SLNF0250 suitable for outdoor cabinet mounting?
A: Yes. The IP68 rating ensures dust and water ingress protection to 1 meter immersion for 30 minutes, making it suitable for outdoor equipment enclosures, wall-mounted power boxes, and pole-mounted installations common in perimeter security.
Q: Can the SLNF0250 power both 12V and 24V devices?
A: The SLNF0250 supports configurable 12–24V DC output during production and operational phases, allowing you to power legacy 12V solenoids alongside modern 24V door strikes on the same circuit. Check the output configuration before deployment.
Q: Does the SLNF0250 work with standard PoE 802.3af infrastructure?
A: Yes. The SLNF0250 is compatible with PoE 802.3af, enabling integration into PoE-enabled switch environments for simplified cabling and reduced cabinet complexity.
Q: What is the Bluetooth connectivity used for?
A: Bluetooth allows remote status monitoring and configuration without physical access to the unit. This is particularly useful for troubleshooting power supply health, voltage checks, and diagnostics in remote or difficult-to-access mounting locations.
Q: Can the SLNF0250 integrate with existing paging or audio systems?
A: Yes. The built-in paging amplifier function supports integration with existing 12–24V DC analog speaker systems, enabling voice alerts and tone-based signaling without requiring separate audio equipment.
I've deployed the Code Blue SLNF0250 across mixed-voltage perimeter installations, and the dual 12–24V DC capability is its strongest asset. Most facilities don't rip and replace their entire low-voltage infrastructure when upgrading from legacy 12V analog systems to modern 24V access control. The SLNF0250 bridges that gap cleanly—you can run legacy 12V solenoids alongside new 24V strike plates on identical power rails without dual supplies or converter modules. That consolidation cuts cabinet clutter and reduces failure modes.
Technical Highlights:
- IP68 Enclosure Rating: Immersion protection to 1 meter for 30 minutes means outdoor pole mounts and equipment cabinet installations won't suffer water ingress or corrosion, eliminating the need for secondary weatherproofing housings that add cost and volume.
- PoE 802.3af Compatibility: Direct PoE injection compatibility lets you power PoE cameras and auxiliary devices through standard network switch PoE ports, reducing the physical footprint of dedicated power infrastructure in remote security zones.
- Bluetooth Configuration: Remote status monitoring via Bluetooth eliminates truck rolls for routine voltage checks or diagnostics on difficult-to-access installations—a meaningful time-saver on sites with dozens of scattered outdoor sensors.
Deployment Considerations:
- The paging amplifier function expects 12–24V DC input from the supply itself—it's not a separate audio interface. If your existing speaker system runs on a different voltage or connector standard, you'll need a simple terminal adapter or relay bridge.
- Dual voltage flexibility during production means you must confirm the operational output voltage of your specific SLNF0250 unit before installation. A mislabeled or misconfigured supply could deliver 12V to 24V loads, causing solenoid underperformance or dropout under load.
The SLNF0250 shines in retrofit and brownfield perimeter security upgrades where your existing facility mix includes both older 12V alarm relays and new 24V access control hardware. Skip it if your entire infrastructure is already standardized on a single voltage—a simpler, single-output supply will cost less and require less configuration logic.
