Fire Alarm Wiring (Public)

To utilize the fire alarm feature on our current fan lines, you will want to tie your normally-closed relay into the orange and orange/white wires of the CAT5 for most fan models*. This is typically done at the ground level.

For standard remotes and Controller 4s, the orange and orange/white wires are heat-shrinked together inside the remote enclosure. You can separate the orange and orange/white wires and land the wires from your normally-closed relay here.

For Controller 30, the CAT5 jacketing will need to be stripped back to reveal the orange and orange/white wires. You will then need to strip those wires and land the wires from your normally-closed relay here.

For AirLynk, there is a terminal block on the outside of the AirLynk panel that has a jumper on it. Remove the jumper and land the wires from your normally-closed relay here.

Alternatively, wires from a normally-closed relay can also be landed directly on the VFD terminals after removing the orange and orange/white wires from the terminals, but we would recommend using one of the above methods instead unless you are using a 0-10V analog remote rather than one of the above remote options.

The fire alarm can be daisy chained so that multiple fans can be shut off from a single relay. Note that this only works for fans of the same model; if there are multiple fan models on site, please reach out to Technical Support for best wiring practices. Please reference national and local codes to ensure compliance in regards to relays and wiring requirements.

For mixed networks containing different fan ages or models, please call us at (866)668-3247 so that we can gather more information to determine the best fire alarm wiring method, as you may experience issues when trying to daisy chain a fire alarm between fans that are not identical.

*The standard VFD remote for the AirLite fan does not have terminals for a fire alarm shutdown. To integrate these fans into a fire alarm system, you will need a separate device that removes the incoming 120V from the building to the VFD controller. However, some custom AirLite controllers are capable of a fire alarm shutdown on the VFD controller. Please contact us at (866)668-3247 for further details.
