Diesel engine fire pump controllers are designed to automatically start a diesel engine driven fire pump upon
detection of an automatic start pressure switch in the fire protection system. A diesel engine fire pump controller
provides automatic & manual starting. An automatic start is controlled by a pressure switch or by remote automatic
devices as deluge valve. The "Operate Manual Start Test Pushbutton" implements a way to simulate the use of the
"Emergency Pushbutton" by being activated after an automatic start followed by a stopping of the Firepump, or
following a "Engine Fail to Start" alarm. A manual start is controlled by an Emergency Start pushbutton, hardwired to
the relay board, that can securely start the engine. The diesel engine fire pump controller includes two battery
chargers to maintain the engine batteries continuously charged.
Types of Diesel Engine Fire Pump Controllers
FIRE PUMP CATALOG NUMBER
MODEL No. EXAMPLE : HFD-12-220
Model Prefix HFD
Battery Voltage 12 : 12V 24 : 24V
Incoming Voltage 220: 208/240V 50/60Hz
Methods of Starting/Stopping
The controllers are available as combination automatic / non-automatic.
MANUAL START
The automatic engine cranking sequence can be started by pressing the START push button on the ViZiTouch.
REMOTE MANUAL START
The engine can be started from a remote location by momentarily closing a contact of a manual push button.
OPERATE MANUAL START TEST
The engine can be started by using this pushbutton after a “Fail to Start” alarm or after an automatic start followed by
a stop. This method of starting will activate the last cranking starters that did not attempt to crank, and is in parallel
with the “Emergency Start” button.
EMERGENCY START
The engine can be started from the Emergency Start Push Button located behind the breakable cover.
REMOTE AUTOMATIC START, DELUGE VALVE START
The engine can be started from a remote location by momentarily opening a contact of a pressure switch.
SEQUENTIAL START
In case of a multiple pump application, it may be necessary to delay the starting of each motor when there is a water
pressure drop to prevent simultaneous starting of all motors.
MANUAL STOP
Manual stop is done by pressing the STOP push button. Note that pressing the stop push button will stop the engine
only if all starting causes have disappeared.
