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 TRBL_# SMOKE DET 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
