Wiring: Esfr (Early Suppression Fast Response) - BIG ASS FANS Pivot 180 Installation Manual

Wiring: ESFR (Early Suppression Fast Response)

WARNING: Wait three minutes after disconnecting before servicing!
WARNING: Improper installation can cause electric shock or damage to the motor and controller. A qualified electrician
should perform the installation.
ATTENTION: If installing the fan in the United States, the fan must be installed per the following National Fire Protection
Association (NFPA) guidelines:
• The fan must be centered approximately between four adjacent sprinklers.
• The vertical distance from the fan to the sprinkler deflector must be at least 3 ft (91.4 cm).
• The fan must be interlocked to shut down immediately upon receiving a waterflow signal from the alarm system.
The fire relay included with the fan is needed only if the fan will be installed in a building that has a fire sprinkler system. The fire relay
integrates the fan with the sprinkler system and shuts down the fan upon receiving an alarm signal from the system. If the building in
which the fan will be installed has a sprinkler system, you must install the relay according to the instructions below.
A contact closure across the digital input terminals 4 and 13A will result in fan shutdown. The included relay uses a Normally Open
(N.O.) contact as shown below. The relay coil must be energized by the FACP for fan shutdown. Optionally, the normally closed (N.C.)
relay contact can be used. The relay coil must remain energized by the FACP for fan operation. This would be considered a fail safe or
fail open wiring arrangement. Two additional relay coil leads are provided to facilitate supervision pass-through where required.
Relay is mounted to the
backside of the access cover.
