In-Duct Sensor Housing
HVAC air ducts in buildings supply fresh air and exhaust stale air. Depending on the overall fire detection requirements, smoke detection may be required in the air ducts. For applications where sampling tube type duct detection is not appropriate due to low air velocity or small duct size, in-Duct Sensor Housings can be used to install the TrueAlarm analogue sensor directly in the duct.
