6020031A — Commercial HVLS Fans
November 2016
This fan includes a fire alarm jumper for a building fire control
systems option that allows the fan to be shut down by the fire
control system in case of a fire emergency.
NOTE:
Ensure that the fire alarm jumper is in place or the building
fire control system is connected and jumper removed.
1. The normally closed (NC) contacts must be dry contacts.
They open in the event of an active fire alarm.
2. The fire control system fan shutdown option is not
enabled when shipped. To enable the fire control system
fan shutdown option, remove jumper and route a pair of
conductors to a set of customer supplied N.C. contacts
in the building's fire alarm panel. See Fig. 25.
3. To test the fire control system fan shutdown operation
remove the wire from the NC contact at the building fire
control panel. The fan should coast to a stop.
If the jumper is left installed the fan will not shut down
due to fire control system contacts.
FIRE CONTROL SYSTEM FAN SHUTDOWN — OPTIONAL
