Description
The Johnson Controls WHA-GM2-03 is a purpose-built A2L refrigerant sensor extension cable designed to extend the reach of compatible A2L refrigerant sensors by 3 meters (10 feet). As A2L refrigerants — such as R-32, R-454B, and R-410A replacements — become the industry standard for next-generation HVAC and refrigeration systems, proper sensor placement is critical for occupant safety and code compliance. This extension cable makes it easy to position sensors at optimal detection heights without compromising signal integrity.
Key Features
- Extends A2L refrigerant sensor reach by 3 m (10 ft)
- Designed for use with compatible Johnson Controls A2L refrigerant sensors
- Supports accurate, low-level refrigerant leak detection for mildly flammable A2L refrigerants
- Allows flexible sensor placement for optimal coverage in equipment rooms, mechanical spaces, and occupied areas
- Plug-and-play design for quick, tool-free installation
- Durable cable construction for long-term reliability in commercial and residential HVAC environments
Applications
- Commercial and residential split systems using A2L refrigerants
- VRF/VRV systems requiring refrigerant leak detection
- Mechanical rooms and equipment spaces with A2L refrigerant systems
- Any installation where sensor relocation or extended cable runs are required
Why A2L Sensor Placement Matters
A2L refrigerants are mildly flammable and heavier than air, meaning leaks tend to accumulate near floor level. Proper sensor positioning — enabled by this extension cable — is essential for early leak detection, helping to meet ASHRAE 15, IEC 60335-2-40, and local safety code requirements. The WHA-GM2-03 ensures your Johnson Controls refrigerant detection system can be installed exactly where it’s needed most.
