Suggested Specification Model MP450 Electric Motor Fire Pump 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 208, 230, 380-415, or 480 volt three phase power.

Controller Equipment Features
The controller shall include the following standard features: 

* NEMA Type 2 drip proof metal freestanding enclosure
* The controller shall be designed for Autotransformer starting and shall start the motor using a heavy-duty motor starting autotransformer, reducing inrush current to 42% of normal using the 65% tap.  Taps of 25% and 80% shall be supplied.
* AUTO, OFF, MANUAL, selector switch with colored LED's for controller mode condition
* 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, system test, lamp test, 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 of language changes
* All controller settings shall be programmable through the OID and shall be protected by two password levels
* All features shall be enabled or disabled through the OID, 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 OID.  The displayed items shall include: System pressure, Phase to Phase (AB, BC, AC) voltage, Phase current (A, B, C), System Events and Notifications, Current time and date, Number of starts, Total motor run hours, Displayed countdown timers for: Sequential motor start and motor stop.
* Audible horn with silence feature for silencable alarms
* Lamp test feature
* Foreign languages selectable through the OID
* Microprocessor based logic with real time/date clock capable of running a minimum of 14 days without AC 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
* Service Entrance Rated

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 OID screens shall be field programmable through the OID.  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 are not allowed.

The user can select any 9 of the following auxiliary alarms that can be programmed and recorded in the event log and annunciated with an OID screen and output relay contact for conditions such as but not limited to:
LOW PUMP ROOM TEMP
RESERVOIR LOW
RESERVOIR EMPTY
RESERVOIR HIGH
FLOW METER ON
RELIEF VALVE OPEN
LOW SUCTION PRESSURE
HIGH PUMP ROOM TEMPERATURE
LOW FIREWATER PRESSURE
LOW PURGE PRESSURE
LOW GEAR OIL PRESSURE
HIGH GEAR OIL TEMPERATURE
GAS DETECTION
HIGH VIBRATION
EMERGENCY POWER ON 
PUMP ROOM DOOR OPEN

Data logging
The controller shall have separate data logs for storing system data that is readable through the OID.

Pressure Log: The controller shall have a Pressure log with continuous pressure recording of 30 days of data.  The pressure log samples shall be time and date stamped and stored on a removable SD card memory.  The pressure log shall be searchable by each sample, by minute, or by hour. Each days entries shall be stored in a separate file on the SD card. SD memory shall be readable by any PC equipped with an SD memory card reader.

Event Log: The event log shall be capable of storing no less than 3000 events.  These events shall include, but is not limited to, any of the following events/alarms:
PUMP RUNNING
POWER AVAILABLE
PHASE REVERSAL
MOTOR OVERLOAD
REMOTE START
LOCAL START
PUMP ON DEMAND
SYSTEM FAULT
AUTO MODE
MANUAL MODE
OFF MODE
PRESSURE TRANSDUCER FAULT
PUMP FAILED TO START
LOW INTAKE SHUTDOWN ALARM
SUPERVISORY POWER FAILURE
LOW PRESSURE
AUTO WEEKLY TEST START
UNDER FREQUENCY
OVER FREQUENCY
LOW ZONE / HIGH ZONE CONTACTS
HIGH DISCHARGE PRESSURE
NO LOAD CONDITION

Each event or alarm recorded in the event log 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
* Motor Running Status
* Phase to Phase Volts 
* Phase Amps 

The internal logic of the controller shall be capable of operation in a temperature range of 0ºC to 50ºC and high, non-condensing, humidity levels.

The controller shall be manufactured by Metron.
