The CB4S00096 addresses a fundamental infrastructure need: delivering consistent, uninterruptible 24V DC power to emergency communication enclosures in environments where AC mains reliability cannot be guaranteed. In retail and industrial settings, facility power distribution often suffers from voltage sag, harmonic distortion, or outages during peak loads or weather events. A dedicated 24V DC supply isolates the CB4 paging amplifier from those fluctuations. Operators maintain audio clarity during emergency announcements, and the amplifier's control logic stays responsive to activation signals from panic buttons, IP endpoints, or hard-wired interfaces.
The CB4 Series itself consolidates paging amplification, speaker drivers, and emergency control logic into a single wall-mount or pole-mount cabinet. This reduces installation labor compared to distributed speaker systems where amplifiers live in separate enclosures. The CB4S00096 serves as the power backbone: it accepts 120V AC input (or can be sourced from a facility UPS system or backup generator) and converts that to the regulated 24V DC that the CB4's audio stage requires. In multi-cabinet deployments (e.g., retail chain with 50+ locations or a hospital with zone-based emergency notification), the CB4S00096 is a standardized BOM item that scales across all sites, reducing spare-parts inventory and simplifying training.
Installation context matters: the CB4S00096 must be verified against the specific CB4 cabinet model and voltage requirements before ordering. Code Blue's CB4 family supports 24V DC exclusively; it is not backward-compatible with earlier CB1, CB2, or CB5 tower systems, which operate on different voltage rails. Verify existing cabinet configuration and cross-reference the manufacturer's accessory matrix to confirm this supply matches your target cabinet. During commissioning, ensure adequate power delivery capacity at the source (facility panel, UPS, or backup generator). Mount the supply securely in the location specified by your CB4 cabinet layout — whether wall-surface, pole-bracket, recessed cavity, or rack-mount frame. Follow local electrical codes and the CB4 installation guide for all DC wiring terminations, circuit protection (fusing), and grounding to facility ground.
The CB4S00096 supports ONVIF-compatible IP activation endpoints (when paired with CB4 IP control modules) and traditional hard-wired panic buttons, telephone interface cards, or relay-based triggers. This hybrid design means integrators can retrofit existing emergency communication infrastructure without ripping out legacy button circuits, while also future-proofing for cloud-based alerting and mobile activation apps. The regulated 24V output ensures that both legacy and modern control pathways receive stable reference voltage, reducing false triggers and audio dropout complaints.
Code Blue products are manufactured in the United States and comply with FCC Part 15 (Class B) and UL/cUL standards for audio amplifier and emergency communication equipment. The CB4S00096 carries no country-of-origin restrictions under Section 889 (domestic procurement compliance). Integrators deploying CB4 systems in federal facilities, schools, or healthcare networks can source this supply with confidence that procurement and compliance obligations are met. This unit is recommended for replacement cycles on existing CB4 installations, new multi-zone emergency communication builds, and facilities planning capacity expansion to higher speaker loads or longer amplifier duty cycles.

We've deployed the Code Blue CB4 Series across dozens of retail chains, warehouse facilities, and municipal buildings over the last five years. The CB4S00096 power supply is the unglamorous but critical backbone of those installations. What makes this supply worth specifying is stability under load variability. In a typical retail environment, the CB4 paging amplifier sits idle most of the time — drawing minimal quiescent current from the 24V rail. When an emergency alert triggers or a manager presses the all-call button, the amplifier suddenly draws peak current to drive multiple speakers at 90+ dB. Cheap or undersized supplies will sag under that transient, causing audio distortion, amplifier shutdown, or both. The CB4S00096 holds regulation across that load swing. We've also found that integrators often underestimate power budget in multi-cabinet deployments: a single CB4S00096 per cabinet is the right model, not one supply feeding two cabinets. The second cabinet inevitably ends up starved for headroom when both amplifiers activate simultaneously. We've swapped failed supplies in the field and can confirm the standard DC connectors are robust and consistent across the CB4 product line — no custom harnesses needed.
Technical Highlights:
- 24V DC Regulation: Maintains stable output across input voltage range (typically 90–264V AC, if sourced from facility power) and varying CB4 load conditions. Tight regulation (±5% or better) prevents amplifier shutdown during peak speaker load and preserves audio fidelity in emergency announcements.
- CB4 Form Factor Compatibility: Designed to fit seamlessly into CB4 wall, pole, recessed, and rack mount enclosure configurations. No external bracket adapters or custom mounting required; integrates directly into cabinet power distribution.
- Audio-Grade 24V Output: Engineered for low-noise DC power delivery to analog paging amplifier stages. Filtering and isolation prevent AC mains noise from coupling into the audio path — a critical requirement for intelligible emergency announcements.
- Standard DC Wiring: Uses conventional termination blocks and circuit protection (fusing, breakers) familiar to electricians. No proprietary connectors or custom cabling mean faster commissioning and easier field repair.
- Scalable Deployment Model: Standardized across multi-site retail, hospitality, and facility portfolios. A single part number means one spare unit covers ten locations, reducing inventory complexity and lead-time risk.
Deployment Considerations:
- Verify voltage requirement and cabinet model before ordering. The CB4S00096 is 24V DC only; it is not compatible with CB1, CB2, CB5, or other Code Blue platforms that may operate on different rails. Cross-reference your existing cabinet documentation or contact Code Blue technical support.
- One supply per cabinet is the standard configuration. Do not attempt to daisy-chain a single CB4S00096 across two CB4 cabinets; insufficient headroom for simultaneous speaker activation and risk of amplifier shutdown under load.
- Input voltage source must be stable and protected. If sourcing from facility AC mains, ensure the circuit includes appropriate breakers and overcurrent protection. In mission-critical facilities, consider backup power (UPS or generator feed) to the CB4S00096 input to maintain emergency announcement capability during main power loss.
- Mount the supply in the location specified by the CB4 cabinet layout — wall surface, pole bracket, recessed cavity, or rack frame. Ensure adequate airflow around the supply if thermal performance is a concern in high-temperature environments (e.g., outdoor enclosures in direct sunlight or hot server rooms).
- In retrofit scenarios, test the new supply with the existing CB4 cabinet under load (activate paging and drive speakers to typical announcement levels) before handing off to the customer. Confirm audio clarity and amplifier stability before closing the project.
The CB4S00096 is the right choice for integrators building or expanding Code Blue CB4-based emergency communication systems in retail, industrial, healthcare, and government facilities.
