Proper orifice sizing is vital for safe operation

Manual Reset Mechanism: Requires a physical inspection by a technician before the system can restart

making it compatible with most standard residential condenser mounting straps

while a lower limit will cause short cycling and premature wear on the inducer and gas valve

or obstructed ductwork

System Sensor DST10 Tube Proper orifice sizing is vitalThe System Sensor DST10 is a heavy duty metal duct sampling tube engineered for duct smoke detection across wide span HVAC systems. Designed for use with both conventional and intelligent duct detectors, specifically the InnovairFlex series, this 10 foot rigid sampling pipe ensures consistent air pressure flow to the sensor chamber. It is rated for duct widths from 8 ft to 12 ft, providing reliable smoke detection airflow in large scale commercial air
