Code Blue CB4R00001 24V Paging Amplifier
Overview
The Code Blue CB4R00001 is a 24V DC paging amplifier designed for wall, pole, recessed, and rack mounting in commercial audio and access control environments. The model provides audio input capability and operates on standard 24V DC power, making it suitable for integration with existing facility infrastructure that already runs distributed 24V systems — common in access control, door locks, and intrusion panels.
This unit's IP68 rating means it can handle direct water jets and partial submersion, a critical advantage if you're mounting it outdoors, in mechanical spaces with condensation, or near loading docks where washdown occurs. The CB4R00001 addresses the need for ruggedized audio distribution in facilities where standard office-grade amplifiers fail within months.
Key Features
- 24V DC Power Supply: Eliminates the need for a separate low-voltage power line. If your facility already distributes 24V to locks, card readers, or access panels, you can tap that same supply. Simplifies infrastructure and reduces installation labor on multi-building campuses.
- Audio Input Support: Accepts audio signals from paging controllers, VoIP endpoints, or emergency notification systems. One input feed can drive the amplifier without additional conditioning gear.
- IP68 Environmental Rating: Rated for submersion and direct spray, meaning rain, dust, and washdown water won't degrade performance. Essential for outdoor speaker cabinets, rooftop antenna enclosures, or humid mechanical rooms where corrosion kills standard amplifiers in one season.
- Multiple Mount Options: Wall, pole, recessed, and rack mounting give you flexibility in tight spaces — mount it vertically on a stairwell wall, horizontally on a utility pole, embedded in a suspended ceiling, or racked in a comms closet alongside your access control panel.
- PoE (802.3af) Compatibility: While the CB4R00001 runs on 24V DC natively, PoE 802.3af sourcing means you can power it from standard network infrastructure if you have available budget on a PoE switch — no separate power conduit required.
- Paging Amplifier Function: Purpose-built for mass notification and emergency voice alerting. If you're upgrading from a single analog intercom to a facility-wide paging system, the CB4R00001 handles the audio amplification stage without the noise or distortion of consumer-grade equipment.
Integration & Compatibility
The CB4R00001 is engineered to work with existing paging controllers and emergency notification platforms that source 24V DC or PoE power. Audio input is standard RCA or XLR (verify with your integrator), and the unit's compact form factor means it fits into rack PDUs, wall-mounted enclosures, or pole-mounted cabinets without special adapters. Because it operates on 24V DC, it integrates seamlessly with access control systems — many commercial panels distribute 24V auxiliary power for exactly this use case.

Frequently Asked Questions
Q: Can the CB4R00001 be powered from a standard PoE switch?
A: Yes. The CB4R00001 supports PoE 802.3af power sourcing, so if you have available power budget on a PoE switch, you can eliminate a separate 24V DC supply. However, verify your switch's total PoE budget before committing — a single paging amplifier is typically modest load, but a multi-zone system with several units requires planning.
Q: What audio sources can I connect to the CB4R00001?
A: The CB4R00001 accepts audio input from any paging controller, VoIP endpoint, emergency notification system, or intercom capable of driving line-level or mic-level audio. Your installation team will confirm impedance and connector type during commissioning.
Q: Is the CB4R00001 suitable for outdoor mounting?
A: The IP68 rating makes it suitable for outdoor weather exposure — rain, dust, and washdown water are handled. However, verify mounting orientation and cable sealing with your integrator; IP68 applies to the enclosure body, not cable glands unless they are also IP68-rated connectors.
Q: What mounting options are available for the CB4R00001?
A: The unit supports wall, pole, recessed, and rack mounting. Choose based on your facility layout: wall mounting in a lobby or corridor, pole mounting on outdoor utility structures, recessed mounting in a suspended ceiling, or rack mounting in a comms room alongside your access control or network infrastructure.
Q: Can the CB4R00001 be used with existing 24V access control systems?
A: Yes. Many commercial access control panels provide auxiliary 24V DC outputs specifically for powering external devices like amplifiers, relay modules, and strobes. The CB4R00001 is designed for this integration pattern.
The CB4R00001 lands in a category where most integrators reach for consumer-grade audio amplifiers — and then curse when they fail in humidity or fail to integrate with 24V infrastructure. The Model CB4R00001 changes that equation by accepting 24V DC natively while delivering IP68 ruggedness, which means it survives washdown zones and outdoor mounting without the constant replacement cycle that kills cheaper equipment.
Technical Highlights:
- 24V DC Power Native: Eliminates a separate power supply line if your facility already distributes 24V for access control locks and readers. Simplifies commissioning and reduces points of failure — one supply, multiple devices.
- IP68 Environmental Rating: Rated for direct submersion and spray jets. If your paging speakers are mounted on a rooftop, in a mechanical room with condensation, or near a loading dock, standard amplifiers corrode within months. The IP68 enclosure survives that punishment.
- PoE 802.3af Fallback: If 24V DC supply is unavailable in a particular zone, you can source power from a PoE switch instead. Flexibility without redesigning your power architecture.
Deployment Considerations:
- Verify your paging controller's output impedance matches the CB4R00001 input spec — mismatched impedance causes distortion or clipping that survives initial testing but appears during live emergencies.
- IP68 applies to the enclosure body only. Cable glands and connectors must also be sealed to realize full submersion rating — work with your installer to confirm all cable entries meet environmental requirements.
Deploy the CB4R00001 in multi-building campuses where centralized 24V supplies already feed access panels, or in hazardous locations (car washes, outdoor loading docks, humid mechanical rooms) where standard audio amplifiers fail. The combination of 24V integration and IP68 ruggedness makes it the right choice for facilities that cannot afford emergency notification downtime.
