Suggested Specification Model MP420 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.

The controller shall include the following standard features:
* NEMA Type 2 drip proof metal freestanding enclosure
* The Controller shall be designed for Part Winding starting.  The starting contactors shall operate in sequence to energize a portion of the motor windings on start which reduces inrush current to approximately 65% of normal.  An adjustable timing relay shall be provided to control time between reduced current start and normal running operation.
* AUTO, MANUAL, TEST, and OFF mode buttons illuminated with colored LED's for controller mode operation
* 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
* 12 pushbuttons for easy screen navigation, system mode changes, 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 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), 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
* English or Spanish 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 RS232 Serial Port
* One USB 1.0 Port
* One RS485 Serial 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 OID LED's 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/alarm logs and annunciated with an LED and output relay contact for conditions such as:
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 three separate data logs for storing system data that is readable through the OID or printable on the internal printer.  These logs shall be as follows:
Pressure Log: The controller shall have a Pressure log with continuous pressure recording of minimum of 7 days and be capable of storing more than 30 days of data.  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 4000 events.  These events shall include 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
Alarm Log: The Alarm Log shall be a separate subset of the event log and shall display the last 10 alarms recorded in the system.
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
* 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 0 Degrees C to 50 Degrees C and high, non-condensing, humidity levels.

The controller shall be manufactured by Metron.
