Modes of Operation
There are four modes of system operation for the
FPD-7024: Alarm, Supervisory, Trouble, and
Normal.
3.1.1 Alarm
When an alarm occurs, the top line of the display
shows ALARM (XXX), where XXX indicates the
number of alarms. This display overrides any other
system display. The second line of the display
gives more instructions. When the group is entered
by pushing the [6/
►
] key, more details of the event
appear. The top line shows the number of alarms
and the point that is in alarm. The bottom line
alternates between the instructions and the
programmed description for the affected point. The
built-in sounder turns on with a steady tone, and
outputs programmed to activate with the existing
alarm condition(s) activate.
When the control panel is not scanning the inputs,
as during smoke power reset, alarm verification
delay, or on-site programming, the trouble LED
flashes to indicate this condition.
3.1.2 Supervisory
When a Supervisory condition occurs, Supervisory
(XXX), XXX indicates the number of supervisory
conditions. The second line of the display gives
more instructions. When the group is entered by
pushing the [6/
►
] key, more details of the event
appear. The bottom line alternates between the
instructions and the programmed description for
the affected point. The built-in sounder beeps.
Outputs programmed to activate with the existing
condition(s) then activate.
3.1.3 Trouble
When a trouble condition occurs (such as cut
wiring for a point or AC power fails), the sounder
beeps every 10 seconds. The Trouble LED lights
and the LCD shows TROUBLE (XXX). When the
[6/
►
] key is pressed the group is entered and more
detail appears. The system can diagnose and
show a variety of trouble conditions, including
those affecting the input points, NAC circuits,
power, battery, system grounding, and internal
operations of the fire control panel. Notify your
installing company immediately if the system
trouble message appears.
Press the [Silence] key to silence the system
trouble beep.
3.1.4 Acknowledge
When the control panel is off-normal, the control
panel’s piezo (buzzer) can be silenced without
silencing the NACs or resetting the control panel.
Press the [ACK] button on the local or remote
keypad to silence only the piezo.
