Air Conditioning Duct Smoke Detectors

Always check with the local code authorities before making a decision about where to install smoke detectors in an air handler or ductwork.

Air conditioning duct smoke detectors.

Presence of smoke in the hvac ducts is detected by sampling the airflow through the duct via two sampling tables. Typical smoke detection devices used for duct application include smoke detector sensors within a housing mounted outside the duct utilizing sam. This eliminates interference caused by outside smoke or heat strip dust accumulation burnoff. Hvac duct smoke detection.

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. Innovairflex duct smoke detectors combine an impressive collection of innovations to greatly simplify hvac system monitoring. Duct detectors located on the return side and upstream of any filters or introduction of outside air detect smoke coming from an air conditioned space. A duct smoke detector is a device or group of devices used to detect the presence of smoke in the airstream of ductwork sections of the hvac air handling systems typically used in commercial buildings.

Inside the probe a detector and base are mounted within a sampling chamber. Yes whenever the air capacity in the ductwork or air handler exceeds 2000 cfm s the smoke detector needs to be installed in the ductwork or handler downstream of air filters and upstream of any branch ducts.
