Notes
1.
Mininum air velocity for smoke detector operation is 100 fpm (2.5 m/s). Maximum is 4000 fpm (20.3 m/s).
2.
Since the smoke detector is not rated for use at velocities below 100 fpm (2.5 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 installation of the damper and
smoke detector.
3.
Holes on sampling tube must face into airstream.
4.
Smoke detector specifications are:
Operating temperature range: -4°F to 158°F
(-20°C to 70°C)
Operating humidity range: 10% to 95% R.H.
Operation voltage: 24 VAC/DC or 120 VAC (50/60 Hz)
