Belimo 22G02-5B Gas Monitor
The Belimo 22G02-5B is a field-reliable carbon monoxide gas monitor designed specifically for demanding HVACR applications such as commercial parking garages, maintenance facilities, and mechanical rooms. Utilizing a high-accuracy electrochemical sensor, this unit delivers precise CO detection 0-250 ppm to ensure ASHRAE-compliant ventilation control. This monitor is engineered for seamless Building Automation System (BAS) integration, featuring native BACnet MS/TP and CAN bus communication protocols. For localized control, the device includes 2x SPDT relay outputs rated at 5A, allowing for direct sequencing of exhaust fans or alarm strobes. Built with an IP65 rated enclosure, it operates reliably in temperatures from -4°F to 122°F, powered by a standard AC/DC 24V supply. The integrated LCD display provides real-time field diagnostics and concentration levels, simplifying commissioning for technicians and ensuring long-term system stability and safety in enclosed vehicle spaces.
Key Benefits for Contractors:
- Broad Integration Support: Native BACnet MS/TP and CAN bus capabilities allow for simplified wiring and direct mapping into the front-end controller.
- Dual Control Hardware: Dual SPDT auxiliary switches provide flexible, hardwired safety interlocks even if the network communication is interrupted.
- Rugged Environmental Protection: The NEMA 4X / IP65 housing protects internal electronics against moisture and dust in harsh mechanical environments.
- Field-Serviceable Design: Features a user-friendly LCD for immediate on-site calibration verification and status monitoring without needing external tools.
- Wide Operational Range: Reliable performance in unconditioned spaces with an ambient temperature range of -20°C to 50°C.
Common Installation Questions:
How do I wire the Belimo 22G02-5B for BACnet communication?
The unit utilizes a standard RS-485 interface for BACnet MS/TP. Ensure you use shielded twisted-pair cable and correctly set the MAC address and baud rate via the internal menu or DIP switches to ensure the building management system recognizes the node.
What power supply is required for this gas monitor?
This monitor operates on a 24V AC/DC power input. For large-scale HVACR projects, ensure the transformer is sized to handle the current draw of both the sensor and the internal relays.
What is the recommended height for mounting CO sensors?
Since carbon monoxide has a similar density to air, the Belimo 22G02-5B should typically be mounted at "breathing zone" height, approximately 5 feet (1.5 meters) above the finished floor, away from direct air intakes or corners with stagnant airflow.
