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.

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 Controller Status Signals Battery A healthy Battery B healthy Battery A boost charge on Battery B boost charge on Controller Alarm Signals Pump on demand Engine running Engine failed to start When lit, press test start Remote alarm signals (Volt free contacts) Pump on demand Engine running Engine failed to start D.C. battery supply failure Controls and instrumentation Combined A.C./D.C. supplies isolator (door-interlocked) Emergency manual start pushbutton (behind break glass flap) Manual start test pushbutton Alarm reset pushbutton Battery charger A ammeter Battery charger B ammeter Battery A/B automatic duty selector switch Engine hours run counter DC Isolated lamp Audible alarm ORDER CODE EFP 12V 120V LPC2000 OPTIONS 24V 230V When ordering, please specify; Engine manufacturer and model number.
