Smoke Detectors
Smoke detectors are available as factory-installed options on
50TC models. Smoke detectors may be specified for supply-air
only, for return-air without or with economizer, or in combina-
tion of supply-air and return-air. All components necessary for
operation are factory-provided and mounted. The unit is facto-
ry-configured for immediate smoke detector shutdown opera-
tion; additional wiring or modifications to unit terminal board
may be necessary to complete the unit and smoke detector con-
figuration to meet project requirements.
Units equipped with factory-optional return-air smoke detec-
tors require a relocation of the sensor module at unit installa-
tion. See Fig. 108 for the as-shipped location.
Completing Installation of Return Air Smoke Sensor:
1. Unscrew the two screws holding the Return Air Smoke
Detector assembly. See Fig. 109, Step 1.
2. Save the screws.
3. Turn the assembly 90 degrees and then rotate end to end.
Make sure that the elbow fitting is pointing down. See
Fig. 109, Step 2.
4. Screw the sensor and detector plate into its operating posi-
tion using screws from Step 1. See Fig. 109, Step 3.
5. Connect the flexible tube on the sampling inlet to the sam-
pling tube on the basepan.
