) Detectors 2 Installation Guide
SAE-1062 Duct Mount
1. Cut a 1-1/4" hole in the duct for the air sampling
tube.
2. Insert the probe into the hole and mark the
enclosure mounting holes. (See Illustration 4.)
3. Remove the unit and drill the four mounting
holes. (Clean all drilled holes of debris before
mounting the device.)
4. Mount the enclosure to the duct with four sheet
metal screws such that the duct air flow is paral-
lel with the vent holes in the probe (i.e., air flows
directly into the probe holes). To prevent air
leaks, ensure the gasket is compressed around
the probe between the device enclosure and the
air duct.
5. Open the cover by removing the two screws and
releasing the latch. (See Illustration 3.)
6. Attach conduit to the conduit opening.
7. Feed wires through the conduit opening, and
connect to the terminals according to the wiring
instructions.
8. After wiring, plug the conduit with plumber’s
putty, painter’s putty, caulk, or other sealant to
prevent air infiltration from affecting accuracy of
the duct readings.
9. Check that the rubber gasket is placed correctly
between the enclosure and cover.
10. After wiring, configuring, and testing the unit,
close and latch the cover. Secure it with the two
screws.

3. To access the mounting holes, CAREFULLY
remove the circuit board from the base by gently
pressing the enclosure base to unsnap the latch
near the bottom edge and lifting the circuit board
from the backplate.
CAUTION
Follow proper electrostatic discharge procedures
when handling the circuit board and be careful to
not touch the sensors.
4. Set the circuit board aside until the base is
mounted on the wall.
5. Attach the universal backplate/base directly to
a standard electrical box using two screws. (See
Illustration 2.)
6. After the base is secured, pull the wires through
the wiring hole in the center of the circuit board
and then reinstall the board in the enclosure base.
Ensure the circuit board is snapped into the base
securely and correctly.
7. After wiring, configuring, and testing the unit,
reinstall the cover and screw.
The duct type sensor installs on the outside of a
return air duct with the sampling tube inserted into
the duct.
Choose a mounting location in a straight section of
a return air duct. Mount at least 5 feet (or 7.5 duct
diameters) from corners or other items that may
cause disturbances in the air flow. Avoid areas prone
to vibration or rapid temperature changes.
