Code Blue SLNF0185 4G LTE Cellular Module
Overview
The Code Blue SLNF0185 is a WEm NP 4G LTE module designed to add cellular connectivity to security installations in locations where wired network access is unavailable or unreliable. This module integrates into surveillance systems via its cellular interface, enabling remote monitoring and data transmission over 4G LTE networks. The SLNF0185 is rated IP68, meaning it can handle direct spray and temporary immersion — relevant if you're mounting it in damp equipment enclosures or outdoor cabinets where condensation is a concern.
Key Features
- 4G LTE Cellular Connectivity: Delivers internet access over cellular networks, eliminating dependency on wired broadband. Critical for remote sites, mobile units, or locations where DSL or fiber installation is cost-prohibitive.
- IP68 Environmental Rating: Fully sealed against dust and water immersion — no water ingress during temporary submersion. Suitable for outdoor equipment vaults, utility cabinets, and marine or wetland surveillance installations.
- Dual Power Input — 277V AC and 24V DC: Accepts both line voltage and low-voltage sources, giving you flexibility to integrate with existing facility power systems (277V three-phase common in commercial buildings) or standard security 24V DC supplies. This dual-input design simplifies installation across mixed electrical infrastructure.
- PoE (802.3af) Support: Can operate on standard Power over Ethernet when 24V DC is derived from a PoE-injected source. Reduces cable run requirements on small deployments where a single run can deliver both data and power.
- Audio Input Capability: Includes audio input for integration with paging amplifiers and two-way communication systems during active events. Useful for campuses, parking facilities, or warehouses where voice alerts complement video alerting.
- Multiple Mount Options: Wall, pole, recessed, and rack mounting configurations allow flexible placement in mechanical rooms, exterior equipment boxes, or standard 19-inch racks — adapts to your site's physical constraints without requiring custom fabrication.
Integration & Compatibility
The SLNF0185 is positioned as a cellular transport module for security systems. Its dual voltage design (277V AC / 24V DC) and PoE compatibility mean it can integrate into traditional hardwired security infrastructure or hybrid wired-wireless networks. The audio input supports connection to paging amplifiers, enabling coordinated alerting workflows. Mount flexibility — wall, pole, recessed, or rack — accommodates integration into equipment rooms, outdoor cabinets, or telecommunications closets without site-specific modifications. When cellular is the primary or backup WAN, the SLNF0185 bridges that gap.
Frequently Asked Questions
Q: What power sources can the SLNF0185 accept?
A: The SLNF0185 accepts both 277V AC (three-phase or single-phase common in commercial buildings) and 24V DC (standard security supply voltage). It also supports PoE (802.3af) when 24V DC is supplied via a PoE injector or switch.
Q: Is the SLNF0185 suitable for outdoor installations?
A: Yes. The IP68 rating ensures complete dust protection and temporary immersion capability, making it suitable for outdoor equipment enclosures, utility cabinets, and damp environments. Ensure it is installed inside an appropriate outdoor-rated cabinet or junction box for long-term weathering.
Q: Can the SLNF0185 work with existing 24V DC security systems?
A: Yes. The module accepts 24V DC input directly, allowing direct integration with existing security power supplies and PoE-based systems without additional converters.
Q: What mounting options does the SLNF0185 support?
A: The module supports wall, pole, recessed, and rack mounting. This flexibility allows installation in equipment rooms, outdoor cabinets, mechanical closets, or standard 19-inch racks depending on your site topology.
Q: Does the SLNF0185 include audio input for two-way communication?
A: Yes. The module includes audio input capability for integration with paging amplifiers, enabling voice alerts and two-way communication in security workflows.
The Code Blue SLNF0185 addresses a real problem: remote sites without wired broadband. The dual power input (277V AC and 24V DC) is the spec that makes this module adaptable — it means you're not locked into a single facility power architecture. Many cellular modules force you to choose one voltage; this one handles both, which saves redesign work when you're retrofitting a mixed-voltage campus or facility.
Technical Highlights:
- IP68 Environmental Rating: Full immersion protection means no water ingress into the enclosure during heavy rain or temporary submersion — critical for outdoor equipment vaults where condensation and spray are routine. You can install the SLNF0185 in an exterior cabinet without extra environmental conditioning.
- Dual Power Input (277V AC / 24V DC): Eliminates voltage conversion in most deployments. A 277V facility can feed the module directly; a 24V DC security system can do the same. Reduces external power conditioning and simplifies troubleshooting — fewer power converters means fewer points of failure.
- PoE (802.3af) Compatibility: When 24V DC is sourced from a PoE switch or injector, you consolidate data and power into a single run — valuable on small remote sites where every cable run costs money and time to install.
- Audio Input for Paging Integration: The module accepts audio input, enabling connection to paging amplifiers and two-way systems. In campuses or large facilities, this allows the cellular module to participate in emergency alerting workflows without additional interfaces.
Deployment Considerations:
- The SLNF0185 is a transport module — it adds cellular WAN access but does not handle video encoding, analytics, or NVR functions. Pair it with a compatible recorder or edge device to complete the surveillance chain.
- While IP68-rated, the module should be installed inside a rated outdoor enclosure for long-term weathering — the rating protects against temporary submersion, not continuous outdoor exposure. Budget for a proper equipment cabinet if the deployment is fully exposed.
- Audio input is a paging amplifier connection, not a built-in microphone. Source your audio from a separate sensor or intercom system in the field.
This module fits well in remote surveillance backhaul scenarios — think distributed warehouse sites, utility substations, or mobile command vehicles where reliable internet is intermittent. The dual voltage input and audio integration make it a practical bridge between legacy 24V security infrastructure and modern 4G cellular transport.
