The FSW800 Series
air-flow monitor
provides a simple
but reliable alternative
to indicate positive or
negative air flow of fans.
When properly installed and
connected in series with an optical
(i.e. LED) or audible signaling
device, a bi-directional switch will
activate an electrical contact if the
air flow of the fan falls below 8.2 ft/s,
thus either turning the signaling
device on or off.
