    SMOKE DETECTORS Smoke detectors are available as factory-installed options on 581J models. Smoke detectors may be specified for supply air only, for return air without or with economizer, or in combina- tion of supply air and return air. Return air smoke detectors are arranged for vertical return configurations only.

    Air is introduced to the duct smoke detector sensor’s sensing chamber through a sampling tube that extends into the HVAC duct and is directed back into the ventilation system through a (shorter) exhaust tube. The difference in air pressure between the two tubes pulls the sampled air through the sensing chamber.
