The circuit monitor can operate up to two detection zones and one releasing zone. The
choices for detection are spot heat detectors, linear heat detectors, remote manual
actuation buttons. The 50 PSI switch can also be connected in the detection circuit to
signal the panel of a pneumatic manual actuation, but does not act as a heat detection
device. These class B devices can be used in any combination by connecting in series. An
end of line module (EOL) is always required at the end of the class B circuit. All detection
cables and components are color coded green.
