FIRE PUMP CONTROLLER
for Diesel Engine Fire pumps
EFP/LPC2000
Logic based release 3.0 spec 3/9806
Complies to BS5306, LPS and EN12845

FEATURES
The Metron Eledyne Autostart type EFP/LPC/2000 Diesel Engine Fire Pump Controller is
designed in accordance with the requirements of BS5306 part II and LPC regulations (Formerly
FOC Rules- 29th Edition) for automatic and manual starting of diesel-driven firewater pumps
for automatic sprinkler installations. There is also an option to upgrade this controller so that it
meets the diesel engine standard LPS1239. (Option LPS). A simple software adjustment also
means that this controller can fully comply to EN12845.
Components are mainly mounted on a printed circuit board and modular for ease of
maintenance. These are contained in a wall mounting, sheet steel, dust and drip-proof
enclosure (IP51) with lock-up front access door. External wiring terminates at a clearly
marked terminal rail.
CONTROL SYSTEM
‘Autostart’ operation powered by engine
batteries only - independent of other
sources of power and is initiated by
sprinkler system low pressure as standard.
Other initiating signals can also be
accommodated.
The controller is designed to provide up to six
repeat 15 second cranks in a start cycle from
the selected automatic battery, each crank
separated by a dwell period of 10 seconds. In
the event of the selected automatic battery
set failing, the controller automatically selects
the alternative battery set for the remaining
cranks. If the engine fails to start after the
sixth attempt, the controller will lock-out and
initiate a failed to start alarm. Cranking is
discontinued immediately following the
detection of an engine run signal. An integral
repeat start unit is provided, which
disengages the crank solenoid momentarily if
the starter fails to correctly engage under
automatic start conditions.
Manual Test Start facility (pushbutton
initiated) is enabled after an automatic
start, and indicates a visual warning
indicator that manual test start is required.
The manual test start and emergency
manual start facilities are independent of
the autostart test control system.

Two independent fully-automatic battery
chargers are incorporated, each with
maximum output current limited to 5 or 10
Amps with constant potential output at
trickle charge to prevent battery gassing.
Boost charge facility and charge rate
ammeter are provided for each battery
charger. Battery voltmeter and selector
switch are available as an optional extra.
Additional engine instrumentation gauges
and monitoring systems are available as
optional extras.

SPECIFICATIONS
The door is lockable by use of the top door
lock and AC isolator. The AC isolator is door
interlocked and maybe be locked in the off
position for maintenance purposes.
The controller can be adjusted by software
to comply with EN12845. The nature of the
change relates to the crank sequence. In
this mode, the auto crank cycle alternates
the cranking battery from A to B after each
crank attempt. The duty selector switch is
not required for EN12845 versions.
NEW LPS1239
COMPLIANT
The EFP/LPC2000 controller can now
be upgraded so that it can be
connected to a diesel engine which is
approved to LPS1239.
The upgrade includes: (See option
‘LPS’ on the option list)
• Isolated output for engine
mounted tachometer
• Protected engine jacket heater
output, 1.5kW
• Low Jacket temperature alarm &
monitor
• Engine stop solenoid output and
push button

8 Amp battery chargers.
Standard battery charger, with manual boost facility
10Amp battery charger.
‘FM’ style automatic boost equalize float type. (Will require a larger than standard
enclosure)
Mains failure start
Adjustable electronic timer which activates the automatic start sequence after the
time delay is completed.
Electronic speed switch (standard)
Takes an electronic pulse from the engine and determines when the engine is
running.
Electronic speed switch (Fiat type)
Same as B1, but for Fiat type engines.
Auto stop timer
Electronic adjustable timer to automatically stop the engine once pump on demand
has cleared.
Delay start timer (Sequence start)
This is used to prevent the engine from starting upon a sudden pressure drop, thus
ensuring that the engine is only started in a true low pressure situation. This option
can also be used on multiple pump installations to prevent the pumps from starting
simultaneously. It is accomplished by the use of an adjustable timer supplied in all
controllers except the lead controller.
Dual meter; Tachometer & voltmeter
EN12845:2004
When this option is selected the controller shall be designed to meet the
requirements for EN12845:2004. A different crank cycle is enabled, and the duty
selector switch is omitted.
Engine oil pressure gauge
Engine water temperature gauge
Engine tachometer
