Essential Info

Your heating and air conditioning system does a great job of moving air throughout your home - but what if there's a system malfunction or a fire? You don't want your HVAC system spreading the smoke and combustion gasses to other areas, you want the system to shut down and notify you. This in-duct smoke detector will do just that. Using a sampling tube, it constantly tests the air inside your HVAC system, looking for smoke and combustion gasses. When everything is normal, there's a flashing green LED on the unit. When it detects these harmful elements, it lights a red LED and energizes its two relay outputs. One can be connected to a strobe light or siren, and one can be used to shut down your HVAC system.

Requires the use of a properly-sized sampling tube:
for ducts between 6" and 30" in width
for ducts between 2.5' and 5' in width
for ducts between 5' and 10' in width
