Chapter 1: Overview

The Alarm Out connector is conn
ected to a strobe light. When the
temperature of the Fan unit
exceeds the maximum operating temp
erature
and stops operating, it changes t
he circuit from closed to open. This
change triggers the strobe light to
turn on. When the temperature of the
Fan unit goes down to the no
rmal operating range and the Fan uni
t
operates
normally, it
changes the
circuit from o
pen to
closed. This
change
triggers the strobe light to turn
off.
