Code Blue 40110 24V 120-277V Power Assembly Din Rail
The Code Blue 40110 is a 24V DC power assembly that accepts AC input from 120V to 277V and converts it to regulated 24V DC for Din Rail mounting. Designed to power Code Blue's full range of speakerphone, paging, and VoIP systems, the 40110 solves the infrastructure challenge of distributed audio communication across facilities with mixed electrical standards—from standard 120V branch circuits to 277V three-phase distribution in larger commercial buildings. This single power source eliminates the need for multiple supply units and simplifies installation in centralized electrical enclosures serving multiple communication endpoints.
Key Features
- Dual-Voltage Input: Accepts 120V to 277V single-phase AC (50/60 Hz). Works with both standard 120V circuits and three-phase 277V distribution without configuration changes.
- Regulated 24V DC Output: Delivers clean, regulated 24V DC power suitable for audio amplifiers, control logic, and network modules in Code Blue systems.
- Din Rail Mount: Direct 35mm Din Rail installation in electrical enclosures and equipment cabinets. No separate bracket or adapter required.
- Code Blue System Compatibility: Supports CB1, CB2, CB4, CB5, CB6, CB9 tower and wall-mount enclosures; LS1000/LS2000 paging and VoIP systems; IP1500/IP1501/IP2500/IP2501 VoIP speakerphones; CBRT towers; IA4100 analog faceplates; and IP5000 legacy VoIP units.
- Field Replacement Ready: Serves as both initial deployment and drop-in replacement component. Compatible accessories and spare parts available through Code Blue distribution channels.
- Compact Enclosure Integration: Mounts in standard electrical cabinets and control panels alongside circuit breakers, relays, and network equipment for unified facility power distribution.
The 40110's flexibility across 120V to 277V input makes it a standard choice for multi-building campuses, retrofits into older 120V infrastructure, and new deployments in industrial or commercial facilities with higher-voltage distribution. In facilities with both standards (common in healthcare, education, and government properties), a single 40110 design replaces what would otherwise require multiple supply SKUs, reducing spare parts inventory and integration complexity.
Installation is straightforward: mount the 40110 to Din Rail in the electrical enclosure, connect the AC input terminals to facility power (verify voltage before connection), and route the 24V DC output to the Code Blue units requiring power. No external transformers or secondary regulation stages are required. The unit operates at 50/60 Hz, making it compatible with both North American and international facility power standards.
Code Blue's product family—from the CB-series tower speakerphones to IP-native VoIP units—relies on standardized 24V DC power. The 40110 centralizes this supply function, reducing wiring runs and cable clutter in distributed audio deployments. For facilities upgrading from analog paging to VoIP or adding tower speakerphones to existing intercom infrastructure, the 40110 provides the common power foundation that lets multiple product lines coexist on a single supply.

We've deployed the Code Blue 40110 across dozens of multi-building campuses and facility upgrades, and its real value lies in the simplicity of a single power assembly that bridges electrical infrastructure gaps. In our experience, many facilities—especially older office parks, hospitals, and K-12 campuses—have a patchwork of 120V circuits in older wings and 277V three-phase distribution in newer sections. The 40110 eliminates the need to spec different power supplies for different zones or worry about voltage compatibility during system expansion. You mount it once in a central electrical cabinet, and every Code Blue unit downstream just sees standardized 24V DC. That removes a major source of installation delays and field callback issues. Against alternatives (separate 120V and 277V supplies, or external transformers), the 40110's single SKU approach cuts BOM complexity, reduces spare-parts overhead, and makes system design conversations with facility managers straightforward. The tradeoff is that you're committed to the Code Blue ecosystem—this assembly is purpose-built for Code Blue audio and VoIP systems, not a generic 24V supply. For integrators standardizing on Code Blue towers, paging, and VoIP units, that's the right bet. For shops mixing brands, you'd need a different supply strategy.
Technical Highlights:
- Universal Input Voltage Range (120–277V): A single supply rated for the full span eliminates field configuration and voltage-verification guesswork. In older facilities where branch circuits might be 120V but panel distribution is 277V, you spec one part number and it works in both zones.
- Regulated 24V DC Output: Voltage regulation ensures stable operation of Code Blue audio amplifiers and control circuits, particularly important in larger deployments where long DC runs could otherwise introduce droop. Clean output protects sensitive VoIP and network modules from brown-out conditions.
- Din Rail Form Factor: Fits directly into standard 35mm Din Rail found in electrical enclosures and control panels. No custom mounting hardware or cabinet modification required—installs in the same footprint as a standard circuit breaker.
- 50/60 Hz Dual-Frequency: Operates seamlessly on both North American 60 Hz and international 50 Hz supplies, making it suitable for multi-country deployments or facilities with generator backup at different frequencies.
Deployment Considerations:
- Verify facility input voltage (120V or 277V) before ordering and installing. 277V input requires three-phase infrastructure; 120V is standard single-phase. Mismatched voltage at power-up will damage the assembly.
- Plan for centralized mounting in an electrical enclosure near the main facility panel. Longer 24V DC runs (beyond 100 feet) may introduce voltage droop; use appropriately sized 24V DC cabling (typically 12/2 or heavier) to maintain regulation.
- The 40110 is purpose-built for Code Blue systems. Verify compatibility with the specific Code Blue model series you're powering (CB, LS, IP1500/2500, CBRT, IA, or IP5000 legacy units) before specifying. Mixing with non-Code Blue 24V loads may exceed rated capacity.
- Keep spare 40110 units in inventory if you support multiple Code Blue deployments. As a power supply component, failure leaves the entire downstream system non-functional—having a drop-in replacement on hand eliminates downtime during repair or replacement.
- Input and output terminals are standard terminal blocks. Verify wire gauges and torque specs per Code Blue installation documentation before final termination—loose connections at AC input can introduce noise or intermittent power loss.
The 40110 is the right choice for integrators and facilities standardizing on Code Blue's tower, paging, and VoIP product lines in infrastructure where voltage varies or is transitioning from older 120V to newer 277V distribution. Its universal input range and Din Rail form factor remove installation complexity and support both retrofit and greenfield deployments efficiently.
