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 an "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.
