Recommended HT & DPS Sensor & Pick Up Plate Location
- 48–72 inches above finished floor
- On an interior wall whenever possible
- In the general working area of the room
- In an area with free airflow around the sensor
For reliable pressure monitoring:
- Route tubing directly whenever possible
- Avoid unnecessary tubing length
- Do not coil excess tubing
- Avoid sharp bends
- Prevent tubing from being pinched or compressed
- Protect tubing from mechanical damage
- Avoid areas where condensation may collect
Avoid Installing HT Sensors:
- Directly below supply air diffusers
- Near return air grilles
- Near doors or pass-through chambers
- Wall mounting is preferred.
- Ceiling mounting should only be used when required by site conditions and should avoid direct airflow patterns.
