700 Duct Mount 1.0 Description The Detcon Sensor Duct Mount Kit for Model 700 gas detection sensors allows a Detcon Model 700 gas sensor assembly to be mounted so that its sensor is located inside of an air duct, while its transmitter, located outside the duct, is still accessible for calibration and other adjustments. This method of installation is much more economical than the typical sample draw type system that is normally used in such applications.
700 Duct Mount 3.0 Installation 1. Cut clearance hole in duct as shown below. Cutout is the same for square or round ducts. Minimum suggested diameter for round duct is 10 inches to adapt with normal mounting techniques. Adapting to an 8” diameter duct is possible with special mounting techniques. Below 8” diameter is not practical for mounting. 2. Mount the duct mount kit using four 1/4” sheet metal bolts or other appropriate hardware. 3.

700 Duct Mount 4.0 Calibration CAUTION: In high velocity air ducts, air flow may need to be shut down before calibration takes place. 1. Verify that there is no air flow through the duct. 2. Remove the cal port plug. 3. Apply the target gas to the cal port at a flow rate of 500 milliliter per minute for combustible (FP series) and solid state H2S (TP series) sensors. Apply a flow rate of 1000 ml/m for toxic gas (DM series) sensors. 4.
