UL/ FM Tornatech Controller For Fire Fighting Systems
Diesel engine fire pump controllers are designed to automatically start a diesel engine driven fire pump upon
detection of a pressure drop in the fire protection system. A diesel engine fire pump controller provides automatic &
manual starting and stopping. An automatic start is controlled by a pressure transducer or by remote automatic
devices as deluge valve. A manual start is controlled by remote manual button or by controller pushbutton. The
automatic shutdown option provides a 30-minutes automatic stop after automatic start once all starting causes have
returned to normal. The diesel engine fire pump controller includes two battery chargers to maintain the engine
batteries continuously charged.
Types of Diesel Engine Fire Pump Controllers
METHODS OF STARTING
AUTOMATIC START
The controller will start automatically on low pressure detection by the pressure sensor when pressure drops below
the cut-in threshold. The controller must be in automatic mode.
MANUAL START
The engine can be started by pressing the CRANK 1 or and/or CRANK 2 push button, regardless of the system
pressure, when the Main Selector switch is in the HAND position. The Fuel Solenoid Valve will open as soon as a
CRANK button is pressed and will remain in this state.
REMOTE MANUAL START
The engine can be started from a remote location by momentarily closing a contact of a manual push button.
REMOTE AUTOMATIC START, DELUGE VALVE START
The engine can be started from a remote location by momentarily opening a contact connected to an automatic
device. The controller must be in automatic mode.
SEQUENTIAL START
In case of multiple pump application, it may be necessary to delay the starting of each motor in case of water
pressure drop to prevent simultaneous starting of all motors.
FLOW START, HIGH ZONE START
The controller can be started by opening/closing a contact on the FLOW/ZONE START/STOP input.
WEEKLY START
The engine can be started (and stopped) automatically at the preprogrammed time.
TEST START
The motor can be started automatically for a preprogrammed time by pressing the run test button.
METHODS OF STOPPING
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.
AUTOMATIC STOP
The automatic stop is possible only after an automatic start and this function must be activated. When this function
is enabled, the motor is automatically stopped 30 minutes after the restoration of the pressure (above the cut-out
threshold) given that no other run cause is present.
FLOW STOP, HIGH ZONE STOP
If the controller has been started by the FLOW/ZONE START/STOP input and that the signal has returned to
normal, the motor will be stopped given that no other run cause is present.
EMERGENCY STOP
The emergency stop is always possible in any running condition and is done by positioning the main selector switch
to the OFF position.
