Simplex 4098-9750 Duct Sensor Housing 0631104

The Simplex 4098-9750 duct sensor housing provides two-wire operation (no relay output).

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, Simplex® model 4098-9750 and 4098-9751 housings can be used to install the Simplex model 4098-9714 TrueAlarm analog sensor directly in the duct.

These housings mount a spot-type smoke sensor directly into the duct airflow. Proper application requires controlled dust and humidity.
