Smoke Detectors Inside HVAC Returns
Is there an easy was to determine if this smoke detector is specifically listed for installation inside a return air chase?

That is not a smoke detector, it is a siren for an alarm system.

I think this is the siren in the picture.

Plastic smokes when burned.
Even duct mounted smoke detectors are mounted outside the ducts and have a sampling tube going into the duct.

It does appear to be a siren. I assume it is right next to a return-air grille. I see no harm in having it there, unless is interferes with the volume of the alarm, or the manufacturer does not permit it. Originally Posted by Al Roden
