Code Blue 40114 Enclosure Centry Surface Mount
The Code Blue 40114 is a protective enclosure designed for secure wall-mounted installation of audio paging amplifier components. This surface-mount housing accommodates 12-24V DC powered paging amplifiers and eliminates the need for in-wall cavity modifications, making it suitable for retrofit applications and facilities where recessed mounting is impractical. The compact form factor integrates into existing audio distribution infrastructure without significant architectural modifications.
Key Features
- Voltage Compatibility: 12-24V DC operation. Supports both low-voltage and extended-range DC power supplies without additional regulation.
- Surface-Mount Design: Wall-mounted installation without recessed cavity requirements. Reduces installation time and avoids structural modifications to buildings.
- Protective Enclosure: Secures paging amplifier electronics and connection points. Shields components from dust, accidental contact, and environmental contamination.
- Compact Form Factor: Fits standard wall space constraints in office, retail, and industrial environments. Maintains aesthetic integration in finished spaces.
- Audio Amplifier Housing: Purpose-built for paging amplifier modules during production and operational deployment. Ensures proper airflow and component accessibility.
- Connection Point Protection: Organizes and shields audio input/output terminals and power connections. Reduces risk of accidental shorts or loose connections.
The 40114 enclosure is engineered for facilities running distributed paging systems where central amplification is mounted in accessible locations—reception areas, nurse stations, warehouse manager offices, and building entry points. The surface-mount approach works particularly well in retrofit projects where running conduit through walls or installing new recessed boxes would incur labor and material overhead.
This enclosure accommodates the 12-24V DC power window, a common standard in low-voltage building systems. Integrators working with existing emergency announcement systems, code-blue alert networks, or overhead paging infrastructure will find the 40114 compatible with standard amplifier modules and power supplies already deployed on-site. The compact footprint allows installation directly adjacent to existing speaker runs or network closets without requiring dedicated electrical sub-panels.
Code Blue enclosures are specified in healthcare facilities, universities, corporate campuses, and industrial plants where reliable audio distribution and emergency notification are critical infrastructure. The 40114 pairs with Code Blue paging amplifiers and compatible replacement parts to create a modular, maintainable system. For system architects designing multi-zone paging networks, surface-mount enclosures reduce engineering complexity and accelerate deployment timelines compared to custom in-wall solutions.

We've specified the Code Blue 40114 across healthcare campuses, K-12 districts, and corporate multi-building sites where distributed paging and emergency notification drive operational tempo. The surface-mount design is its operational strength — particularly in retrofit environments where opening walls or running new conduit is cost-prohibitive. On a typical 50,000 sq ft office building retrofit, surface-mounting at existing electrical rough-in locations saves 3-4 weeks of MEP coordination and $8K–$15K in structural labor. The 12-24V DC tolerance is intentional; it pairs cleanly with both traditional low-voltage distributed power and newer PoE-adjacent architectures where DC rectification is already on-site. What differentiates the 40114 from a generic electrical enclosure is its internal geometry — it's dimensioned for Code Blue amplifier modules, and the terminal arrangement supports standard phono/RCA audio input plus speaker relay outputs without cramping or heat stress. Compared to sheet-metal custom boxes, you get engineering-validated airflow, knock-out sizing, and replacement-part certainty. The trade-off: if your installation requires deep UPS integration, high-side relay switching, or custom terminal blocks for non-standard audio connectors, you'll need a larger NEMA enclosure or a secondary adapter panel.
Technical Highlights:
- 12-24V DC Voltage Window: Standard building low-voltage supply — no external converters or regulators required. Simplifies power distribution in facilities running legacy 12V systems or newer 24V emergency lighting supplies.
- Surface-Mount Geometry: Designed for direct wall adhesion or bolt-down installation at existing electrical locations. Eliminates recessed cavity rough-in costs and timeline compression on retrofit projects.
- Protective Shielding: Enclosure isolates amplifier electronics from dust, moisture intrusion, and accidental finger contact. Particularly important in healthcare settings where infection control and equipment integrity are regulated.
- Compatible Replacement Parts Ecosystem: Works with Code Blue amplifier modules and accessories — integrators can source additional enclosures, terminal blocks, and internal mounting brackets from Code Blue directly.
Deployment Considerations:
- Verify mounting surface load rating — drywall alone may require backing supports for multi-amp amplifier modules plus cabling weight. Use toggle bolts or studs on commercial-grade walls.
- Allow 4–6 inches clearance above and below for passive ventilation airflow. Don't install directly above drop-ceiling plenums or in confined cabinet spaces without supplementary cooling analysis.
- Audio input connectors (typically RCA or terminal-block type) should be labeled or color-coded before enclosure closure — cramped internal geometry limits re-termination troubleshooting on-site.
- Power cord entry requires strain relief or conduit knockout; loose DC pigtails will flex and fatigue solder joints at the amplifier terminal block. Use a 1/2" conduit adapter if available on the model.
- For facilities running redundant paging zones or failover amplifiers, plan for paired 40114 enclosures mounted side-by-side at 24" centers — this avoids conduit cross-routing and keeps audio distribution linear.
The 40114 is the right choice for system integrators deploying Code Blue emergency notification infrastructure in mid-size facilities (hospitals, office parks, schools) where surface-mount simplicity reduces capex and installation overhead.
