Belimo c-22g-5c Gas Monitor Communication Module

Product Description

The BELIMO c-22g-5c is a gas monitor communication module designed to integrate gas detection sensors into networked building control systems. It supports CAN bus communication, enabling standalone operation or networked configurations of up to 32 devices on a single daisy-chained wiring run. Audible and visual alarms provide immediate local alerts when gas concentration thresholds are reached. Licensed building automation technicians and HVAC controls professionals are the primary installers of this device. It is suited for applications where centralized monitoring and control of gas detection is required across multiple zones or floors.

The c-22g-5c is intended for commercial and industrial environments where gas monitoring must be coordinated from a central location or integrated into a broader building management system. It supports BACnet MS/TP communication protocol, making it compatible with standard BMS platforms. Relay outputs and analog outputs on select configurations allow the module to directly control ventilation equipment in response to gas detection events, eliminating the need for additional control hardware in many installations.

Key Features

• CAN bus communication supports networks of up to 32 devices
• Audible and visual alarms for immediate local gas detection alerts
• BACnet MS/TP protocol for direct integration into building management systems
• Relay and analog outputs available for direct ventilation control
• Daisy-chain wiring topology simplifies installation and reduces cabling
• Backed by a five-year manufacturer warranty

Compatibility

Designed for use with BELIMO gas monitor communication systems supporting CAN bus and BACnet MS/TP networks in commercial and industrial building automation applications.

Installation Notes

Installation should be performed by a licensed HVAC controls technician or building automation specialist familiar with low-voltage communication wiring and BMS integration. Power down the control system and any connected devices before wiring the module into the daisy-chain network. Follow applicable local electrical codes and manufacturer wiring diagrams when making CAN bus and BACnet MS/TP connections. Verify network addressing and alarm threshold settings during commissioning before returning the system to service.
