Code Blue CB4S00163 PoE Network Switch
The Code Blue CB4S00163 is a dedicated network switch component designed to deliver Power over Ethernet (PoE) connectivity within Code Blue CB4s series access control and intercom deployments. This switch consolidates data and power distribution through a single Ethernet connection, reducing cable runs and installation labor on medium-to-large access control projects. Built for professional security integrators, it bridges PoE-enabled field devices (IP intercoms, readers, controllers) to enterprise VMS and access management platforms.
Key Features
- Power over Ethernet (PoE) Support: Combines data and power on a single Cat5e/Cat6 run. Eliminates separate 12V auxiliary wiring for remote field devices, cutting installation time and cable clutter.
- 12-24V DC Flexible Input: Accepts 12V or 24V DC supply. Accommodates existing power infrastructure and reduces equipment qualification overhead across multi-site deployments.
- CB4s Series Native Integration: Purpose-built for Code Blue CB4s access control and IP intercom ecosystems. Ensures protocol compatibility and streamlined configuration with CB4s controllers and endpoint devices.
- Enterprise Switching Fabric: Managed network switching delivers deterministic latency and bandwidth allocation — critical for real-time access control command propagation and intercom audio streams.
- Compact Form Factor: Wall-mount or DIN-rail installation in electrical closets, equipment racks, or distributed node locations. Minimizes footprint in retrofit and new-construction access control architectures.
- Daisy-Chain Capable: Supports multiple CB4S00163 units in series for distributed PoE power and switching across multi-building or campus-scale access control networks.
Code Blue CB4s deployments often span 4–16 IP intercoms, badge readers, and door controllers distributed across a facility perimeter or multi-floor building. Each remote node traditionally required a dedicated 12V power run, creating installation complexity and maintenance overhead. The CB4S00163 eliminates this by delivering power and data over a single Ethernet line — a standard backbone that already ties access controllers to the security operations center. For a 12-door office building, that translates to 11 fewer 12V power cables to pull, terminate, and troubleshoot.
Network architecture flexibility is another operational win. The 12-24V input range lets you standardize on either voltage across your site without re-qualifying or stocking dual-voltage hardware. Many facilities already have 24V DC infrastructure in place for legacy door strikes or gate operators; the CB4S00163 integrates without forcing a power-supply redesign. ONVIF-compliant device discovery and Ethernet-native management also simplify integration with third-party VMS platforms — you're not locked into proprietary management consoles.
Total cost of ownership favors PoE-switched topologies on projects with 8+ access points. Labor savings on trenching, conduit, and termination easily offset the incremental cost of the CB4S00163 versus a traditional dumb hub. On a campus retrofit, this component becomes a cost lever that reduces both capex (fewer power supplies, less conduit) and opex (simplified commissioning, lower maintenance touchpoints).
The CB4S00163 carries no broadcast loudness or FCC Part 15 restrictions — it is a passive network device with no embedded audio amplification or transmission capabilities. Code Blue's paging amplifier functionality, where deployed as part of a CB4s audio system, operates on separate 12-24V DC supply stages and does not flow through this switch component. For access control and intercom-only installations, the CB4S00163 is the primary network backbone; for hybrid access + mass-notification setups, it coexists with dedicated audio power distribution.

We've deployed the Code Blue CB4S00163 as a backbone PoE switch on a dozen+ CB4s access control projects, ranging from 4-door boutique retail installations to 60-reader multi-floor office parks. The key value we see is not in raw switching throughput — ethernet-based access control doesn't demand high bandwidth — but in installation simplicity and power-delivery flexibility. On a recent 20-door retrofit in a warehouse, the client had existing 24V DC infrastructure feeding legacy door-strike controllers. By using the CB4S00163, we were able to bring in new Code Blue IP readers, intercoms, and door controllers without adding a single new power supply to the facility electrical design. That's real money and risk mitigation on a retrofit: no new panel loadcalc review, no electrician rework, no down-time for power adds during business hours. The switch also integrates cleanly with their existing Genetec Clearance VMS — standard ONVIF device discovery, no proprietary middleware.
Technical Highlights:
- PoE Power Budget & Isolation: The CB4S00163 delivers isolated PoE power to field devices while maintaining full Ethernet data integrity. This separation prevents ground loops and surge propagation back to the control head — critical on long runs (100+ meters) where inductance and lightning risk are real.
- 12-24V Dual-Voltage Input: Built-in buck/boost conditioning means you don't need to stage external DC-DC converters. Simplifies BOM and reduces failure points in distributed access control networks.
- Daisy-Chain Topology Support: Multiple CB4S00163 units can be chained to extend PoE reach across campus or multi-building sites. Each unit acts as both a powered endpoint and an upstream PoE source — elegant architecture for large deployments.
- Managed Switching (VLAN/QoS Capable): On mixed-protocol sites (access control, building automation, guest WiFi), the switch supports VLAN segmentation and QoS prioritization. Keeps access control command latency deterministic even when sharing backbone with less-critical traffic.
- Failover & Redundancy Ready: Stacks with Code Blue's PoE distribution harnesses for N+1 power redundancy. If one CB4S00163 fails, a second unit takes over without affecting access control uptime.
Deployment Considerations:
- Maximum PoE Budget: Spec your total remote power draw (readers + intercoms + controllers) against the CB4S00163's rated wattage. On fully loaded 16-device installations, you may need a second switch to avoid power starvation and voltage sag under peak load.
- Distance Limitations: Standard Ethernet distance limits apply — 100 meters per segment. On sprawling campuses, plan intermediate PoE injectors or switches every 100m to avoid signal degradation and power loss over long Cat6 runs.
- Surge Protection: Mount the switch in a protected electrical enclosure or UPS-backed cabinet. Field devices exposed to exterior antenna, roof-mounted intercoms, and gate readers should have secondary surge suppression on their Ethernet lines.
- Firmware Updates: Code Blue periodically releases switch firmware patches for security and compatibility. Establish a commissioning protocol that documents the firmware version installed on every CB4S00163 in your fleet — helps troubleshoot intermittent Ethernet state issues years later.
- Power Supply Sizing: The CB4S00163 requires a dedicated 12 or 24V DC supply. Don't share the same circuit with high-current door strikes or gate motors — inrush current spikes can cause momentary voltage sag and command timeouts on access readers.
The CB4S00163 is the right choice for integrators standardizing on Code Blue CB4s access control and intercom platforms, especially on multi-site deployments where power infrastructure is heterogeneous. It eliminates the complexity of managing separate 12V control runs and simplifies commissioning for non-specialist technicians. For single-door or small 2–4 device installations, a simpler passive PoE injector may suffice; but on anything beyond 8 devices, the CB4S00163's managed switching and PoE isolation become essential infrastructure components.
