Figure 7. Duct Detector Placement - Location of Dampers
3. Locate air duct detectors on the return or supply duct of the equipment’s air
handling system. However, detectors should NOT be installed in the return
air damper branch. See Figure 7.
4. Locate air duct detectors on branch lines if close identification of the alarm
source is required.
5. Locate air duct detectors on the downstream side of filters to sense fire in
filters. However, should the filters block, sufficient air flow may not be
available for proper air duct detector operation. See Figure 7.
6. Whenever possible, locate air duct detectors where they can be
conveniently observed and readily serviced.
7. Locate the air duct detectors in return air ducts ahead of mixing areas.
8. Do not locate air duct detectors next to outside air inlets unless you want to
monitor smoke entry to the handling system from an adjacent area.
9. Locate air duct detectors upstream of air humidifiers and cooling coils.
