2.14. Smoke Detector
When mounting the smoke detector, always refer to the respective device mechanical installation
manual for detailed explanation.
2.15. Duct Mounted Sensors
When mounting duct mounted sensors, always refer to the respective device mechanical
installation manual for detailed explanation. Refer to technical bulletins TB-54 and TB-61.
2.16. Room Mounted Sensors
The room mounted temperature/humidity sensor is a critical part of the system. It measures the
controlled variables and therefore it must be properly installed and located. Select a mounting
location which is the best representation of a typical temperature and relative humidity inside the
room. Keep in mind that some rooms have cold and hot spots. Locating the devices in those
locations can affect the system ability to maintain proper control.
The location of the sensors should consider the following:
•
Mount sensors 5’ - 0” above finished floor.
•
Do not locate wall mounted sensor in the direct path of supply air from the supply grilles.
•
Do not locate wall mounted sensor adjacent to high heat producing electrical equipment.
•
Avoid mounting directly on exterior walls, especially if exposed to solar load. If this is the
only option, mount thermostat on a mounting bracket at least 3” from the wall surface.
•
Consider mounting the wall mounted sensor near the return grille to measure the average
space temperature.
Refer to technical bulletin TB-52 and the respective device installation manual for detailed
explanation.
