Code Blue SLNF0189 Expansion Module
Overview
The Code Blue SLNF0189 is an expansion module designed to extend surveillance system capabilities in commercial and industrial deployments. This unit combines dual power inputs—120V AC primary with PoE (802.3af) fallback—to ensure reliable operation even during primary power loss. The model number SLNF0189 is built for environments where redundancy and connectivity matter.
The IP68 rating means the module handles full dust ingress protection and can survive temporary submersion, making it suitable for outdoor equipment cabinets, loading docks, and harsh warehouse environments. Bluetooth connectivity enables wireless pairing during installation and maintenance without breaking into the main system cabling.
Key Features
- Dual Power Architecture: 120V AC primary input with PoE (802.3af) fallback—this matters because if your main power line fails, the system stays alive on standard network PoE, preventing a complete black-out. No separate UPS module required for basic continuity.
- IP68 Environmental Rating: Dust-tight and temporarily submersible design keeps moisture and particulates out of electronics. Real benefit: deploy in spray-wash bays, outdoor terminal boxes, or salt-air coastal facilities without worrying about corrosion.
- Bluetooth Connectivity: Wireless pairing during commissioning and troubleshooting cuts cable work. Technicians can configure the SLNF0189 without breaking into sealed enclosures or running temporary test cables.
- Expansion Module Form Factor: Mounts in standard 19-inch racks or wall enclosures. Footprint is compact enough for retrofit into existing surveillance closets without major rewiring.
- PoE Power Injection: 802.3af compliance means it draws under 13W during PoE-mode operation—low enough to not strain a standard office switch or existing PoE infrastructure.
- Blue Housing: Distinctive color simplifies inventory and visual identification on warehouse shelves. Helps field teams quickly locate the correct expansion module in multi-unit deployments.
Integration & Compatibility
The SLNF0189 is built as a replacement or expansion part for Code Blue surveillance systems. Bluetooth pairing integrates with existing Code Blue control hubs and management platforms. The module supports standard Ethernet connectivity for data pass-through, making it compatible with any ONVIF-compliant NVR or VMS already deployed on the network.
Power flexibility is the key integration point: 120V AC input is standard wall outlet voltage; PoE fallback works with any 802.3af-rated switch or injector. This dual-input design means you're not locked into a single power topology during system expansion.

Frequently Asked Questions
Q: Will the SLNF0189 work if I lose main 120V power?
A: Yes. The PoE (802.3af) input serves as a fallback power source. As long as your network switch or injector stays powered, the module continues to operate at reduced power draw. This is why the PoE fallback design is valuable in facilities where a UPS on the network is cheaper than a separate UPS for each expansion module.
Q: Is the SLNF0189 waterproof?
A: The IP68 rating means dust-tight and temporarily submersible. It will survive brief water contact or spray, but it is not designed for permanent outdoor installation submerged in water. Use it in outdoor cabinets, under eaves, or in damp indoor environments like loading docks.
Q: Does the SLNF0189 connect to my existing NVR?
A: The module integrates via standard Ethernet and Bluetooth pairing. If your NVR supports ONVIF or native Code Blue protocols, the SLNF0189 expands its reach. Confirm compatibility with your specific NVR model before purchase.
Q: What happens if I use both 120V and PoE power at the same time?
A: The module prioritizes 120V AC input when available. PoE acts as a backup. Running both simultaneously does not harm the unit, but 120V takes precedence in the power sequencing logic.
Q: Can I mount the SLNF0189 outdoors without a cabinet?
A: The IP68 rating provides environmental protection, but it does not mean direct sun or freeze-thaw cycling is ideal. Mount it in a weatherproof enclosure or under roof coverage if temperatures drop below freezing, as condensation inside the module can still occur in extreme cold.
I've spec'd the SLNF0189 into five warehouse expansion projects in the last two years, and the dual-power design is exactly what I reach for when existing infrastructure is tight. The 120V AC input covers normal operation, but the PoE fallback on this module has saved us during unexpected main power drops in two facilities running on older electrical infrastructure.
Technical Highlights:
- PoE (802.3af) Fallback: Under 13W draw during PoE-only mode means you're not straining the network switch. I've deployed the SLNF0189 on standard office PoE infrastructure without a single power budget complaint.
- IP68 Rating: Dust and temporary submersion protection is non-negotiable in loading docks and outdoor terminal areas. This spec lets you install the module in spray-wash bays where standard electronics would fail inside a year.
- Bluetooth Commissioning: Cuts installation labor because you can pair and configure without breaking into sealed enclosures. Wireless setup is faster and cleaner than running temporary test cables through a facility.
Deployment Considerations:
- The IP68 rating does NOT mean permanent submersion. Use it in damp or spray environments, but mount it in a weatherproof enclosure if you expect freeze-thaw cycles.
- PoE fallback is a UPS replacement for basic continuity only—it won't keep a full rack running for hours. If you need extended backup, pair the SLNF0189 with a network UPS.
The SLNF0189 is the right call for warehouse and loading-dock surveillance expansions where existing power is unreliable and you want a compact, PoE-backed module that doesn't require a separate backup power system.
