Code Blue CB4R00120 24V Paging Speaker
The Code Blue CB4R00120 is a 24V DC-powered paging speaker engineered for security and facility management deployments where audio announcements must reach multiple zones without relying on expensive point-to-point wiring. Built for durability and flexible mounting, the CB4R00120 integrates into existing paging amplifier systems running 12–24V DC infrastructure.
Overview
The CB4R00120 is a surface-mount or recessed audio speaker designed to work within paging amplifier networks. It operates on 24V DC power, making it compatible with standard low-voltage security and facility automation systems. The unit supports audio input from paging amplifiers and can be deployed across multiple mounting surfaces—wall, pole, recessed, or rack—depending on your coverage topology. IP68 environmental rating means it tolerates dust and moisture, though submersion is not recommended for extended periods.
Key Features
- 24V DC Power: Draws power from your existing 24V DC distribution network, eliminating the need for separate AC supply circuits in each coverage zone. Simplifies wiring in retrofit installations where AC power is limited.
- Audio Input Support: Accepts paging amplifier output directly, allowing real-time announcements (emergency notifications, zone-level alerts, facility-wide messages) without intermediary processing. One amplifier can drive multiple CB4R00120 units in parallel.
- IP68 Environmental Rating: Dust-sealed and water-resistant. Deploy indoors or in light-weather outdoor applications (loading docks, uncovered shelters, warehouse mezzanines). Not rated for full submersion or continuous rainfall directly on speaker grille.
- Multiple Mount Options: Wall, pole, recessed, and rack configurations support diverse facility layouts. Wall-mounting fits corridors and open areas; pole-mounting works in parking structures and outdoor yards; recessed mounting integrates into drop ceilings in offices and retail floors.
- Paging Amplifier Integration: The CB4R00120 works as part of a distributed paging backbone. Each speaker connects to the amplifier output circuit, allowing zone-based or building-wide announcements without VMS integration overhead.
- Low-Voltage Safety: Operating on 24V DC meets electrical code requirements for Class 2 circuits in most jurisdictions, reducing permitting complexity and installation labor compared to 110V speakers.
Integration & Compatibility
The CB4R00120 integrates into paging amplifier systems operating in the 12–24V DC range. If you are upgrading from an older 12V DC system to 24V, verify your amplifier supports both voltage levels or plan a staged migration. Audio input is passive (amplifier-driven), so no additional audio processing or digital interfaces are required. Mounting hardware is provided for wall and pole installations; recessed and rack configurations may require site-specific brackets.
Deployment Considerations
The CB4R00120 is best suited for facilities with centralized paging systems (security command centers, warehouses, retail stores, office complexes). It is not a networked speaker—there is no IP connectivity, ONVIF support, or VMS integration. If you need individual speaker control, status monitoring, or IP-based audio streaming, you will need a networked paging system instead. For IP-based deployments, explore networked paging solutions designed for your VMS platform.

Frequently Asked Questions
Q: Can I use the CB4R00120 in an outdoor parking structure?
A: Yes, the IP68 rating supports outdoor use in uncovered areas. However, avoid direct submersion or continuous heavy rain exposure. For fully exposed outdoor installations in wet climates, verify mounting angle and drainage with the manufacturer.
Q: What amplifier wattage do I need to drive multiple CB4R00120 speakers?
A: This depends on your amplifier's output impedance and the total speaker impedance load. Consult your paging amplifier documentation or the CB4R00120 impedance rating (not provided in available specs) to calculate total load capacity.
Q: Is the CB4R00120 suitable for IP video surveillance integration?
A: No. The CB4R00120 is a standalone paging speaker with no IP networking, ONVIF support, or VMS connectivity. For integrated audio and video, use networked audio speakers compatible with your surveillance platform.
Q: Can I recessed-mount the CB4R00120 in a drop ceiling?
A: Yes, recessed mounting is listed as a supported option. Verify ceiling thickness and electrical access to the 24V DC feed before installation.
The Code Blue CB4R00120 is a straightforward 24V DC paging speaker—no IP processing, no audio codecs, just clean passive audio distribution. If you're building out a facility-wide paging backbone and need reliable point-to-zone coverage without VMS overhead, the CB4R00120 is the right tool. The 24V DC input and IP68 environmental rating make it practical for mixed indoor-outdoor deployments in warehouses, retail environments, and office complexes.
Technical Highlights:
- 24V DC Power Input: Direct connection to your low-voltage DC infrastructure eliminates circuit-breaker overhead and simplifies code compliance. One 24V DC run can feed multiple speakers, reducing wiring labor versus individual AC-powered units.
- IP68 Rating: Dust and moisture sealed. Deploy in loading docks, uncovered shelters, and outdoor mezzanines without worrying about incidental spray or humidity. Not suitable for full submersion or continuous rain bombardment.
- Audio Input Compatibility: Passive audio input means your paging amplifier drives the speaker directly. No digital interfaces, no network latency, no VMS dependencies—audio announcements reach the zone immediately upon amplifier output.
Deployment Considerations:
- The CB4R00120 is a paging-only speaker. It does not integrate into IP-based surveillance systems, so if you later need synchronized video and audio alerts, plan for a parallel networked audio system.
- Amplifier impedance matching is critical. Confirm your amplifier's output impedance and the CB4R00120's input impedance before installation to avoid underdrive or mismatch distortion across multiple units.
The CB4R00120 excels in facilities where paging announcements need zone coverage without IP complexity—think multi-level warehouses, retail chains, and parking structures where a centralized amplifier feeds dozens of speakers across building zones.
