Introduction
Electric fire pump controllers are designed to start an electric motor driven fire pump. It can either start the fire
pump manually through the local start pushbutton or automatically through the sensing of a pressure drop in the
sprinkler system. The fire pump controller is supplied with a pressure transducer. The fire pump can be stopped
manually with the local stop pushbutton or automatically after the expiration of a field programmable timer. In both
cases, stopping is only allowed if all starting causes have disappeared.

Methods of Starting/Stopping
The controllers are available as combination automatic / non-automatic with provision for manual or automatic
shutdown (an automatic shutdown is only possible after an automatic start).
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 motor can be started by pressing the START push button, regardless of the system pressure.
REMOTE MANUAL START
The motor can be started from a remote location by momentarily closing a contact of a manual push button.
REMOTE AUTOMATIC START, DELUGE VALVE START
The motor can be started from a remote location by momentarily opening a contact connected to an automatic
device.
EMERGENCY START
The motor can be started manually by using the emergency handle. This handle can be maintained in a closed
position.
Important: to avoid damaging the contactor, it is recommended to start the motor in this manner:
1) Shutdown the main power by using the main disconnect means,
2) Pull the emergency handle and lock it in closed position,
3) Turn the power back on by using the main disconnect means.
SEQUENTIAL START
In case of a multiple pump application, it may be necessary to delay the automatic (pressure drop) starting of each
motor 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.
