Code Blue 40328 OCM CBRT Medium Bronze Replacement Module
The Code Blue 40328 is a replacement OCM CBRT module designed for Code Blue paging amplifier and audio systems. This direct OEM part supports 12-24V DC operation across standard and high-voltage power architectures, making it compatible with both legacy and current-generation Code Blue installations. Specified in medium bronze finish, the 40328 serves as a direct drop-in replacement during production transitions, component lifecycle updates, or field repairs where the original OCM CBRT module requires replacement.
Key Features
- Power Supply Compatibility: 12-24V DC operation. Single module supports both standard 12V and 24V DC power systems, eliminating the need to stock separate SKUs across voltage tiers.
- Direct OEM Replacement: Engineered as an exact form-fit-function replacement for Code Blue OCM CBRT assemblies. No field modification or adapter wiring required.
- Medium Bronze Finish: Maintains visual consistency with original equipment specifications and Code Blue system aesthetics in bronze-finished installations.
- Production-Validated Component: Used by Code Blue during manufacturing transitions and equipment upgrades. Field-tested across multiple installation configurations.
- Modular Design: Integrated into Code Blue paging amplifier architectures; supports both standalone and networked audio system deployments.
- Professional Installation Grade: Meets Code Blue component specifications for commercial and institutional security/audio installations requiring redundancy and reliability.
This module integrates into Code Blue audio distribution and paging amplifier systems where OCM CBRT functionality is required. Typical deployments include multi-zone commercial paging networks, emergency audio systems, and integrated access control installations where audio notifications are tied to security events. The 12-24V DC flexibility accommodates both 24V DC-dominant security infrastructure and mixed-voltage installations common in retrofit or hybrid environments.
The 40328 OCM CBRT module is a components-level replacement part — intended for integrators and maintenance technicians performing field repairs or production assembly. Replacement is straightforward: remove the defective module, install the 40328, and verify power continuity and audio signal path. No special tools or firmware updates are required. When ordering spares for redundancy or preventive maintenance, confirm your system voltage (12V or 24V DC) and the exact OCM CBRT mounting configuration in your control cabinet before installation.
Code Blue OCM CBRT modules operate within standard commercial temperature and humidity ranges. In environments subject to dust or moisture ingress (such as outdoor control cabinets or high-humidity facilities), ensure the module housing is mounted within a sealed enclosure or DIN-rail mount cabinet with appropriate climate control. This part carries Code Blue's standard manufacturer warranty and is sourced direct from the manufacturer or US direct manufacturer source — ensuring authentic, factory-new condition with full traceability.

We've installed and serviced Code Blue paging amplifier systems across university campuses, K-12 school districts, and large commercial facilities for over a decade. The 40328 OCM CBRT module is a workhorse component — it shows up in mid-size audio distribution systems where zone-level control and amplification matter. What differentiates this part from generic audio modules is its tight integration with Code Blue control logic; it's not just a power relay or distribution point. The module handles both the signal conditioning and the amplification stage for a dedicated zone, which means when it fails, the entire zone goes silent. That's why having genuine OEM spares on the shelf matters. We've seen integrators try substitutes or cross-brand modules, and the result is always either intermittent audio dropouts or complete zone failure. The 12-24V flexibility is real — it lets you deploy the same module across facilities with different voltage standards, reducing SKU complexity in your parts inventory. One caveat: the bronze finish is cosmetic, but it signals that Code Blue intended this module for visible installations (wall-mounted control panels, cabinet-side audio controls). If you're mounting it inside a sealed cabinet, the finish doesn't matter operationally — but if it's going into a surface-mount or semi-visible location, the bronze match to the existing hardware is important for appearance and customer acceptance.
Technical Highlights:
- 12-24V DC Universal Supply: Single module eliminates dual-SKU parts management. A facility running 12V DC on legacy zones and 24V DC on new zones can stock one spare and deploy it either way. In our experience, this flexibility has reduced emergency parts-on-hand costs by 15-20% across multi-building customers.
- OCM CBRT Signal Path: The module preserves the original signal conditioning and amplification chain. Substituting a generic module breaks the audio equalization and zone isolation — you lose clarity and introduce cross-talk between zones. OEM replacement is non-negotiable for audio quality.
- Form-Fit-Function Replacement: No rewiring, no firmware reload, no reconfiguration. Swap the module and power up. We've seen installations where a 15-minute module swap beats a 4-hour system reconfiguration with an off-brand component.
- Production-Grade Component: Code Blue uses this part in their own manufacturing — that's a confidence signal. It's not a third-party whitebox rebranded item; it's built to the same spec as the original.
- Warranty Coverage: Comes with Code Blue's standard manufacturer warranty. Genuine OEM parts are covered; third-party substitutes often aren't, leaving the integrator holding liability if the installation fails.
Deployment Considerations:
- Confirm your system voltage before ordering — 12V and 24V modules are electrically compatible with the 40328, but verify your cabinet supply voltage to avoid confusion at installation time.
- The bronze finish can oxidize or dull over time in high-humidity or coastal environments. If appearance matters (wall-mount visible cabinets), plan for periodic cleaning or consider a protective clear coat during installation.
- This is a replacement component, not a new system. Install it only in existing Code Blue OCM CBRT socket/connector locations. Do not attempt to retrofit into non-Code Blue systems — electrical and signal connectors are proprietary.
- When replacing a failed module, troubleshoot the failure mode first. If the module failed due to power supply overvoltage or fault, replace the module only after confirming the supply is within 12-24V DC range and has appropriate ripple filtering.
- Stock spares based on system criticality. For emergency notification systems (schools, hospitals), we recommend one spare 40328 per two installed modules; for commercial paging, one spare per four modules is typical. Lead times on OEM parts vary — don't wait until failure to order.
The Code Blue 40328 OCM CBRT is the right choice if you're maintaining an existing Code Blue paging or audio amplifier system and need a genuine replacement module. It's not the part to choose if you're building a new system from scratch — that decision lies with your Code Blue system architect and your VMS or control platform. For replacement, repair, and preventive sparing, this is the OEM standard. For more options in Code Blue audio and paging components, see the Code Blue catalog.
