Notes

1. Minimum air velocity for smoke detector operation is 300

fpm (1.5 m/s). Maximum is 4000 fpm (20.3 m/s).

2. Since the smoke detector is not rated for use at velocities

below 300 fpm (1.5 m/s), local code may require an

alternate means of damper closure such as zone detection

or automated damper closure when the system fan is

shut down. The local authority having jurisdiction should

be consulted prior to the in installation of the damper and

smoke detector.

3. Holes on sampling tube must face into the airstream.

4. Smoke detector speciﬁcations are:

Operating temperature range: 32°F to 100°F

(0°C to 38°C)

Operating humidity range: 10% to 85% R.H.

Operation voltage: 24 VAC/DC or 120 VAC

5. Refer to Hochiki Duct Smoke Detector installation

instructions.

air velocity in duct. For damper activation

r equir ements when system velocity is less

than 300 fpm, the local authority having

jurisdiction should be consulted.
