Wiring for Hood Switch Panels
The diagrams below show a typical hood switch panel remote mounted. For hood mounted switches refer to the wiring connection decal on the cover of the junction box on the hood top.
The diagram below shows how to wire the exhaust and supply fans with a control panel to a fire suppression contact (FSC1). When wired properly, the suppy fan will be turned off if the fire system is activated and allow the exhaust fan to continue to operate.
The fire suppression contact (FSC1) is provided as part of the fire suppression system and is normally mounted in the fire system control box.
