Fire Pump Controllers

1-2

Features

7. Interlock

8. Low

Pressure

9. Auto Shutdown Enabled
10. Programmable LED #1

C. The controller shall be supplied with ten (10) red

alarm LED’s to indicate the following:
1. Phase

Reversal

2. Phase

Failure

3. Fail to Start
4. Undervoltage
5. Overvoltage
6. Low Room Temperature
7. Locked

Rotor

Trip

8.  Low Suction Pressure
9.  Source 2 Disconnected
10.  Programmable LED #2

D. The microprocessor logic board shall be available

with:
1. A USB port for transference of message history,

controller status, diagnostics, and statistics and
the ability to update firmware.

2. An optional Ethernet port for direct connection to

a computer for data transfer.

3. An optional RS485 Serial port for communica-

tion to various external software programs.

E. The controller shall be available with an embedded

web page to allow viewing of the controllers' current
status, data values, programmed set points, and his-
tory.

F. A Fail-to-Start alarm shall occur if the motor control-

ler sees less than 20% of the motor full load amps af-
ter an adjustable time delay of 1-90 seconds.

G. Locked rotor protection shall be provided. After a trip

condition and restoration of power, the LCD display
shall indicate “LOCKED ROTOR TRIP”.

H. A sequential start timer and weekly test timer shall

be provided as standard.

A restart time delay of two (2) seconds shall be pro-
vided to allow the residual voltage of the motor to
decay prior to re-starting the motor. In the event that
the pump motor continues to run after a request to
stop, then the controller must display a fail to stop
message to indicate this condition.

Overvoltage (5-20%) and undervoltage (5-30%)
sensing and alarming shall be provided as standard.

K. The controller shall be supplied with interlock and

shutdown circuits as standard. A flashing green LED
shall indicate an interlock on condition.

L. Where shutdown of the pump(s) due to low suction

pressure is required, it shall be accomplished without
the addition of a separate panel or enclosure. The
LCD display shall indicate low suction shutdown.
Resetting of the condition shall be automatic or ma-
nual as selected by the user.

M. Means shall be provided to test the operation of all

LED’s to ensure their functionality.

7. Programming

Menu

A. The programming menu shall have the ability to ena-

ble an entry password.

B. The programming menu shall be limited to two (2) le-

vels of password protection.

C. The controller shall have three (3) languages as a

standard, English, French, and Spanish, with the
ability to add a fourth language.

D. The programming menu shall be grouped into 6 main

menu headings as follows:
1. Regional

Settings

2. Pressure

Settings

3. Timer

Values

4. Alarm Set points
5. Input/Output

6. System

Configuration (password protected)

8. Pressure

Sensor

A. A solid-state 4-20mA pressure sensor shall be pro-

vided. The pressure Start and Stop points shall be
adjustable in increments of one (1) PSI. A low pres-
sure pre-alarm, indicated with a flashing green LED,
shall denote a potential pump starting condition and
will remain lit once the pump has started to indicate
the starting cause.

9. Custom

Inputs/Outputs

A. The controller shall come standard with nine (9) fu-

ture inputs, two (2) future LED indicators, and one (1)
future output, with the ability to add up to another 8
outputs via optional relay boards.

B. The user shall be able to program the future in-

puts/outputs through the main programming menu.

C. The inputs shall be selectable based on the following

criteria:
1. User selected message or thirteen (13) prede-

termined messages.

2. Energize the common alarm relay when the in-

put is received.

3.  Link to a future relay and/or LED indicator.
4.  Alarm latched until reset.
5.  Normally open or closed input.
6. On-delay
