The Control Panel is of the same design as the Circuit Monitor, but with an added agent
cylinder pressure monitoring circuit and fire relay output signal. The Control Panel 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.
