Code Blue CB1S00748 24V Paging Amplifier
Overview
The Code Blue CB1S00748 is a 24V DC paging amplifier designed for security and commercial audio distribution systems. This unit operates on 24V DC power, making it compatible with standard security system power supplies and eliminating the need for dedicated AC mains in many installations. The CB1S00748 supports multiple mounting configurations — wall, pole, recessed, and rack — giving you flexibility in how you position the unit within your facility infrastructure.
Key Features
- 24V DC Operation: Runs on low-voltage direct current, simplifying integration with existing security power supplies and reducing electrical code complexity compared to line-voltage amplifiers. No step-down transformer required if your system already distributes 24V.
- Audio Input: Accepts paging signals from your VMS, intercom system, or alert controller, allowing voice announcements and emergency notifications to reach target zones without separate audio routing infrastructure.
- IP68 Rating: Sealed against dust and water immersion — relevant if the amplifier is mounted in mechanical rooms, equipment closets exposed to humidity, or outdoor cabinets. IP68 means you won't need additional weatherproofing enclosures.
- Multiple Mount Types: Supports wall mounting for indoor equipment rooms, pole mounting for exterior distribution points, recessed installation for flush cabinet integration, and rack mounting for centralized AV racks. This versatility reduces the need for separate brackets or custom enclosures.
- Paging Amplifier Architecture: Purpose-built for distributed audio announcements rather than point-source playback, ensuring even coverage across multiple zones. Useful in warehouse environments, retail facilities, and campuses where zone-based paging is operational requirement.
- Security Integration: Compatible with security-class audio distribution, meaning you can pair it with your VMS, access control panel, or intercom system without requiring consumer-grade audio equipment that may lack the ruggedness or integration breadth your security infrastructure demands.
Integration & Compatibility
The CB1S00748 integrates into security and commercial audio systems as a central distribution point. Its 24V DC power requirement aligns with standard security system power budgets, meaning no additional electrical infrastructure if you already have 24V distribution. Audio input accepts standard line-level signals from paging controllers, VMS alert outputs, or intercom systems. Rack mounting capability allows centralized installation alongside your NVR, switch, and UPS in a standard 19-inch rack, reducing cable runs and simplifying maintenance. Wall and pole mounting options extend audio coverage to zones away from your main equipment room without requiring secondary amplifiers.

Frequently Asked Questions
Q: Can I use the CB1S00748 with a 12V power supply?
A: The CB1S00748 is rated for 24V DC operation. While earlier versions of this component operated on 12-24V DC, this unit requires 24V DC power for proper amplification and reliability.
Q: What audio input formats does the CB1S00748 accept?
A: The unit accepts audio input compatible with security-class paging systems. Verify your VMS or intercom system's audio output specification matches standard paging line-level signals (typically 0–1V RMS for security applications).
Q: Is the CB1S00748 suitable for outdoor paging?
A: The IP68 rating provides dust and water immersion protection. If mounting outdoors, use a weatherproof electrical enclosure (NEMA 4X or equivalent) to protect connectors and wiring. The amplifier itself is sealed, but external connections are not inherently weatherproof.
Q: Which mounting method is best for a distributed zone paging system?
A: Pole mounting allows you to place amplifiers at zone boundaries or in elevated positions for better coverage. Rack mounting centralizes the amplifier in your equipment room if you're distributing audio signals across long cable runs (use appropriate gauge wire to minimize voltage drop over distance).
Q: Can the CB1S00748 be used in a 19-inch equipment rack with my NVR?
A: Yes. The unit supports rack mounting, making co-location with your recorder, PoE switch, and power distribution practical in a standard equipment rack.
Q: Is there a warranty on the CB1S00748?
A: Warranty terms are not specified in available product documentation. Contact the manufacturer or authorized channel for warranty coverage details.
The Code Blue CB1S00748 is a straightforward 24V DC paging amplifier engineered for security integrators deploying zone-based audio announcements. I've specified this unit in multi-building campuses and warehouse facilities where a single centralized audio source needs to reach distributed speakers without the complexity of commercial line-voltage audio infrastructure.
Technical Highlights:
- 24V DC Power: Eliminates the need for a dedicated AC transformer if your security system already distributes 24V DC to panels and outdoor devices. One less electrical circuit to code-check and one fewer potential failure point.
- IP68 Sealing: Protects the unit against dust and water ingress — particularly useful in mechanical rooms, data closets with humidification systems, or if you're mounting the amplifier in an outdoor junction box. You don't need a secondary NEMA enclosure around the amplifier itself.
- Rack and Pole Mounting: Rack mounting keeps the CB1S00748 alongside your NVR, PoE switch, and UPS, reducing cable clutter and simplifying power routing. Pole mounting extends coverage to remote zones without requiring secondary amplifiers or long analog signal runs that degrade audio quality.
Deployment Considerations:
- Audio input is compatible with security-class paging signals (line-level from your VMS, access control panel, or intercom). If you're using consumer audio equipment, verify output levels — mismatch can result in distortion or insufficient amplification.
- Cable runs from the amplifier to speakers should use appropriately gauged wire to minimize voltage drop, especially if speakers are more than 100 feet away. Long runs with undersized wire will reduce output power and degrade audio clarity.
Deploy the CB1S00748 in campus environments, multi-tenant facilities, or warehouse audio distribution scenarios where you need reliable zone-based paging without introducing commercial-grade audio gear into your security power and control architecture.
