Wiring: Fire signal relay

WARNING: To reduce the risk of electric shock, wiring should be performed by a qualified electrician! Incorrect assembly
can cause electric shock or damage the motor and the controller! Hazard of electrical shock!
CAUTION: Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable
codes and standards.
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.
Note: The illustration below applies to fans installed with either a wired or wireless wall controller.
Note: In the configuration shown, power must be applied to the
fire relay to enable fan operation.
*Note: If this circuit is open, the fire relay will trip. The fan will
shut down and issue a Run Enable Jumper Open error. To
restart the fan, close the circuit and reset power to the fan.
