Controls the speed of a centrifugal pump to limit
the system pressure in a fire sprinkler system.
Firetrol
®
variable speed electric fire pump
controllers provide a variable frequency drive
(VFD) in a PID process control loop to control
the speed of a centrifugal pump for the purpose
of limiting the system pressure in a fi re sprinkler
system. The Mark IIXG monitors the VFD, and if
a problem is detected, switches the controller
to bypass mode. The controllers are available
in the following confi gurations:
FTA3100 - VFD with Across-The-Line Bypass
FTA3110 - VFD with Autotransformer Bypass
FTA3130 - VFD with Digital Soft Start Bypass
The controllers include pilot lights for indica-
tion of Drive Ready and Bypass Active and also
a selector switch for manual bypass operation.
These Controllers are available assembled
with power transfer switches for use with an
emergency generator set or second utility
power source.
Operator Interface
The fi re pump controllers feature an opera-
tor interface with user keypad. The interface
monitors and displays motor operating condi-
tions, including all alarms, events, and pressure
conditions. All alarms, events, and pressure
conditions are displayed with a time and date
stamp. The display is a 128x64 Backlit LCD ca-
pable of customized graphics and Cyrillic type
character display. The display and interface are
NEMA rated for Type 2, 3R, 4, 4X, and 12 pro-
tection and is fully accessible without opening
the controller door. The user interface utilizes
multiple levels of password protection for sys-
tem security. A minimum of 3 password levels
are provided.
