Trouble Operation 4. Operation
AFP-100/AFP-100E Instruction PN 51010:C1 02/06/2002

Acknowledge
Pressing the
ACKNOWLEDGE
/
STEP
key will cause the panel sounder to silence and the System Trouble
LED to turn on steady. This occurs regardless of the number of troubles, alarms and supervisory events
active in the system (block acknowledge). When you press the
ACKNOWLEDGE
/
STEP
key, and at least
one new alarm or trouble exists in the system, the “Acknowledge” message is sent to the printer and
history file. If the trouble clears, either before or after Acknowledge, the “Clear Trouble” message is
sent to the printer as illustrated by the following example:
CLR TRB
L_# SMOKE D
ET P01 <ADJ>
<NOUN> ZONE
# TIME and
DATE
If all troubles clear and there are no supervisory or fire conditions active in the system, the system
returns to normal operation status and the “Systems All Normal” message is shown on the LCD display
and stored in the history and printer files. Trouble restore occurs even if the troubles were never
acknowledged (auto-restore).
If the
ALARM
SILENCE
key is pressed when only troubles exist, it will have the same effect as the
ACKNOWLEDGE
/
STEP
key. The Alarm Silence LED will not be illuminated unless there was also an
alarm in the system.
Note: If a combination of alarms, troubles and/or supervisory conditions occur in the system simultaneously, only the
alarms are scrolled on the display.
If multiple trouble conditions exist in the system, they scroll on the LCD display automatically at a
3-second rate. If the
ACKNOWLEDGE
/
STEP
key is pressed, the display stops on the present item for one
minute or until the Acknowledge/Step key is pressed again. As the
ACKNOWLEDGE
/
STEP
key is pressed,
the control panel displays events in the following priority order:
1. Alarms in address order
2. Supervisories in address order
3. Troubles in address order
