The air duct mounting probe unit enables Eaton’s range of addressable, conventional and two-wire fire alarm system smoke detectors to be installed in heat, air conditioning and ventilation (HVAC) ducts.
Presence of smoke in the HVAC ducts is detected by sampling the airflow through the duct via two sampling tables. Inside the probe, a detector and base are mounted within a sampling chamber. The probe should be installed on the external skin of the duct, with sample and exhaust probes passing into the duct, in an area of low turbulence.
The unit requires an addressable, conventional or two-wire smoke detector and corresponding base to be complete.
