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: 23°F to 131°F (-5°C to 55°C)
Operating humidity range: 10% to 93% R.H.
Operation voltage: 24 VAC/DC or 120 VAC
5. Refer to System Sensor, D4120 Installation and Maintenance
Instructions for further installation details.
6. Refer to System Sensor, D4120, Installation and Maintenance
Instructions for maintenance and field tests.
