PANEL DETAIL
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 shows how to wire the exhaust and supply
fans with a control panel to a fire suppression contact
(FSC1). When wired properly, the supply fan will be
turned off if the fire system is activated and to 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.
