NFPA 70 STANDARD TORNATECH Diesel Engine Fire Pump Controller GFD 24-220
DEMANDS INFO FORM Kathy.pdf
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 such as a deluge valve. A manual start is controlled by remote manual button
or by controller pushbutton. The automatic shutdown option provides a 30-minute automatic stop after automatic
start once all starting causes have returned to normal. The diesel engine fire pump controller includes two battery
chargers to ensure the engine batteries are continuously charged.
Methods of Starting
AUTOMATIC START
The controller will start automatically on low pressure detection by the pressure sensor when the pressure drops
below the cut-in threshold.
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 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.
FLOW START, HIGH ZONE START
The pump 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 manually by pressing the run test button.
