Mounting Instructions
Follow these steps to mount the SD505-ADHR:
1. Remove paper backing from mounting
template (packaged in installation kit) and
affix to duct at installation location.
2. Using the template as a guide, drill the four
mounting holes (3/32” diameter) for duct
detector mounting screws provided (4 # 12 x
1/2” sheet metal screws).
3. Use template as guide to drill or punch holes
for the sampling tubes in the air ducts (1-
3/8” diameter).
4. Clean all holes.
Sampling Tube Assembly
The sampling tubes can be ordered in standard
lengths and cut per requirements. See chart
below for available standard sizes. The intake
sampling tube is a piece of steel piping with a
series of holes drilled the entire length of the
tube. The tube should be cut to a size that allows
it to extend the entire width of the duct.
The holes must be facing into the air flow (see
Figure 1). The exhaust tube is a piece of steel
piping measuring 7 inches.
