Smoke Detector Locations
SUPPLY AIR
The supply air smoke detector sensor is located to the left of
the unit’s indoor (supply) fan. See Fig. 51. Access is through
the fan access panel. There is no sampling tube used at this lo-
cation. The sampling tube inlet extends through the side plate
of the fan housing (into a high pressure area). The controller is
located on a bracket to the right of the return filter, accessed
through the lift-off filter panel.

Location
RETURN AIR SMOKE DETECTOR SENSOR WITHOUT
ECONOMIZER
The sampling tube is located across the return air opening on
the unit basepan. See Fig. 52. The holes in the sampling tube
face downward, into the return air stream. The sampling tube is
connected through tubing to the return air sensor that is mount-
ed on a bracket high on the partition between return filter and
controller location. The sensor is shipped in a flat-mounting lo-
cation. Installation requires that this sensor be relocated to its
operating location and the tubing to the sampling tube be con-
nected. See installation steps.

Location
RETURN AIR SMOKE DETECTOR SENSOR WITH
ECONOMIZER
The sampling tube is inserted through the side plates of the
economizer housing, placing it across the return air opening on
the unit basepan. See Fig. 53. The holes in the sampling tube
face downward, into the return air stream. The sampling tube is
connected using tubing to the return air sensor mounted on a
bracket high on the partition between return filter and control-
ler location. The sensor is shipped in a flat-mounting location.
Installation requires the sensor be relocated to its operating lo-
cation and the tubing to the sampling tube be connected. See
installation steps below.

Completing Installation of Return Air Smoke
Detector
Use the following steps to complete the installation of the re-
turn air smoke detector.
1. Unscrew the two screws holding the return air sensor
detector plate. See Fig. 54. Save the screws.
2. Remove the return air smoke sensor module and its detec-
tor plate.
3. Rotate the detector plate so the sensor is facing outwards and
the sampling tube connection is on the bottom. See Fig. 55.
4. Screw the sensor and detector plate into its operating position
using screws from Step 1. Ensure the sampling tube connec-
tion is on the bottom and the exhaust tube is on the top.
