Suggested Specification Metron Model FD4 Diesel Engine Controller

General Controller Description
The Fire Pump Controller shall be factory assembled, wired and tested as a unit and shall conform to all requirements of the latest edition of NFPA 20, NFPA 70 and be Third Party Listed by Underwriters Laboratories (UL) and Approved by Factory Mutual (FM).  The controller shall be available for either 12VDC or 24VDC systems.
Controller Equipment Features
The controller shall include the following standard features:
* NEMA Type 2 drip proof metal wall mount enclosure
* Dual Battery chargers, 10 amp microprocessor temperature compensated with integral volt/amp digital display and integral LEDs for indication of AC Power On and Battery Power On
* Two outer door mounted crank pushbuttons and two inner panel mounted battery on/off switches
* Outer door mounted key operated AUTO, OFF, MANUAL, mode selector switch 
* Operator Interface Device (OID) with 4 lines by 20 character display with large character backlit LCD capable of being read in both direct sunlight or dark lighting conditions
* 10 pushbuttons for easy screen navigation, alarm reset, and horn silencing
* Multicolored LED’s for alarm and mode annunciation
* LEDs shall be labeled with removable labels to allow for easy field modification if additional alarms and/or language changes
* All controller settings shall be programmable through the OlD and shall be protected by two password levels
* All features shall be enabled or disabled through the OlD, no jumpers or external wires shall be needed or allowed to activate or de¬activate a feature
* The system status data shall be displayed on the OlD.  The displayed items shall include:
System pressure, Battery 1 Voltage, Battery 2 Voltage, Battery 1 Charger Amps, Battery 2 Charger Amps, Lead starting battery, Current time and date, Number of starts, Total engine run hours, Displayed countdown timers for:
Sequential engine start and engine stop, and Time until AC Power fail start.
* Audible horn with horn silence feature for silenceable alarms
* Lamp test feature
* English or Spanish languages selectable through the OlD
* Microprocessor based logic with real time/date clock capable of running a minimum of 14 days without DC power connected to controller and non-volatile flash memory to permanently store the continuous pressure log, event log, alarm log and all user changeable set points and system data.  Battery backup of any kind not allowed.
* Input and output status LED’s to provide visual indication of each discrete input’s or output’s on/off status
* One RS485 Serial Port
* MODBUS Communication Protocol via RS485 port
* All wiring terminals on PCB’s shall be removable type
Auxiliary alarms:
As standard the controller shall include 6 discrete auxiliary inputs, 9 form ‘C’ auxiliary relay outputs.  These auxiliary inputs and outputs are in addition to those mandated by NFPA 20.  All auxiliary inputs, outputs, and OlD LED’s shall be field programmable through the OlD.  This permits a multitude of customizable controller configurations to meet each installations unique needs without adding cost to the controller.  The use of jumpers, soldering, or other external components is not allowed.
The user can select any 9 of the following auxiliary alarms that can be programmed and recorded in the event/alarm logs and annunciated with an LED and output relay contact:
ENGINE QUIT FAULT
HIGH ENGINE OIL TEMPERATURE
PRESSURE TRANSDUCER FAULT
LOW JACKET WATER FLOW
PUMP ON DEMAND

Data logging: The controller shall have separate data logs for storing system event and pressure data that is readable through the OlD or printable on the internal printer.  The data logs shall be stored on a removable SD memory card. The file format shall be standard ASCII text. These logs shall be as follows:
Pressure Log: The controller shall have a Pressure log with continuous pressure recording one month of data.  Each day’s data shall be in a separate file. The pressure log samples shall be time and date stamped and stored in permanent non-volatile flash memory.  The pressure log shall be searchable by each sample, by minute, or by hour.
Event Log: The event log shall be capable of storing no less than 3000 events.  These events shall include any of the following events/alarms:
BATTERY 1 FAULT
SYSTEM AUTO MODE
BATTERY 2 FAULT
ENGINE LOCKOUT SIGNAL
BATTERY 1 LOW VOLTAGE
SYSTEM AUTO MODE
BATTERY 2 LOW VOLTAGE
SYSTEM MANUAL MODE
CHARGER 1 FAULT
SYSTEM OFF MODE
CHARGER 2 FAULT
SYSTEM TEST RUN
AC POWER FAIL
ALARM RESET
ENGINE OVERSPEED
LOW PRESSURE CONDITION
ENGINE FAILED TO START
LOW PRESSURE START
ENGINE QUIT
DELUGE START
ENGINE LOW OIL PRESSURE
REMOTE START
ENGINE HIGH WATER TEMP
AC POWER FAIL START
PRESSURE TRANSDUCER FAULT
HORN SILENCED
STOP PUSHBUTTON PRESSED
PRESSURE DROP
(PLUS ANY OF THE 9 PROGRAMMABLE AUXILIARY ALARMS LISTED ABOVE)

Each event or alarm recorded in the either event log or alarm logs shall have the following data recorded with the event/alarm:
* Time and Date of Event or Alarm
* System Pressure
* Descriptive Text Message of the Event/Alarm
* System Auto Mode Status
* Engine Running Status
* Charger 1 Status
* Charger 2 Status
* Battery 1 Status
* Battery 2 Status

The internal logic of the controller shall be capable of operation in a temperature range of 0°C to 40°C and high, non-condensing, humidity levels.
The controller shall be manufactured by Metron Inc.
