System Pressure Connection
The FD100 is supplied with a Pressure Transmitter
or, as an option, a Pressure Switch. The controller
is provided with a 1/4" NPT female system
pressure connection located on the bottom,
external side of the enclosure. The connection
should be installed as per NFPA, pamphlet No. 20.
The “TEST” drain connection, located to the left of
the system pressure connection, should be piped to
a drain or to waste.
The main controller panel interfaces with either the
pressure transmitter or the optional pressure
switch. The controller must be programmed for the
appropriate device.
Using the standard pressure transmitter, the actual
pressure is displayed on the top right hand corner
of the LCD display. Precise start and stop pressure
set points can be programmed into the controller
via the membrane switches. Pressure readings are
also displayed on the printer during alarm
situations or pressure deviations.
With the Pressure Switch option, the LCD will
display “OK” if the pressure is satisfied, and
“LOW”, if the contacts on the pressure switch
change state. The printer will indicate “Low
Pressure” on the paper display when the pressure
drops below the set point.

display panel indicates both the voltage and current
reading of each battery as well as the system
pressure, in PSI.

utilized at any time during the operation of the
diesel controller.
4.7 Time/Print Button
This button toggles between two functions. When
initially depressed the LCD display will indicate:
When depressed again, the controller will prompt
the user to hold the button for 3 seconds (at which
time an audible tone is heard) after which the
stored event and alarm messages will be
transmitted to the printer. This is only applicable
when the ‘Print Routine’ is set for
Manual Print,
otherwise the data is sent directly to the printer
without user intervention. Refer to Section 14. The
“Time/Print” key is not functional when the
controller is in the OFF mode.
