Lennox 22H56 Detector Kit
This Lennox 22H56 Smoke Detector Kit is a critical safety component designed for seamless integration with commercial Lennox rooftop units, including high-performance models in the Model L, Enlight, and Raider series. Engineered for reliability in demanding environments, this photoelectric smoke detector provides rapid response by sensing combustion particles within the supply and return air streams. As a veteran-grade OEM HVAC replacement part, it ensures full compliance with local building codes and industrial fire safety standards without the compatibility issues common in generic retrofits.
The kit features a robust single-sensor smoke detector housing (utilizing the D4120 or D4S base architecture) and includes all necessary hardware for a secure duct smoke detector installation. By monitoring airflow directly, the 22H56 triggers immediate system lockdown or alarm status to prevent the circulation of smoke throughout a facility. This prevents property damage and ensures occupant safety in warehouses, hospitals, and manufacturing plants. For technicians, the unit’s compact design allows for quick mounting and electrical termination, keeping project timelines on track and system downtime at a minimum.
- Universal Compatibility: Specifically designed for Lennox HVAC units such as the KC, KG, KH, LC, LG, and LH series (156-360 models).
- Advanced Sensing: High-accuracy photoelectric technology reduces nuisance trips while maintaining high sensitivity to smoldering fires.
- Industrial Durability: Built to withstand the temperature fluctuations and vibration levels typical of roof-mounted commercial equipment.
- Streamlined Installation: Comprehensive duct detector kit components simplify the integration into existing CORE Control Systems.
Common Questions
Is the Lennox 22H56 compatible with both supply and return air applications?
Yes, this detector is designed to be installed in either the supply or return ductwork of supported Lennox commercial units to monitor for smoke infiltration effectively.
Does this kit include the sampling tube and mounting hardware?
The 22H56 kit typically includes the detector head, base, and essential mounting components. Always verify the required sampling tube length based on your specific duct width before initiating the HVAC safety sensor installation.
How can I test the sensor after installation?
Technicians can perform functional tests using approved aerosol smoke or by utilizing the integrated magnetic test switch to ensure the duct sensor is communicating correctly with the rooftop unit's controller.
