CKNOWLEDGING
Each and every alarm event that takes place on the system is required to be individually Acknowledged. This
acknowledgment process confirms to the system that an operator is aware of the situation and as such the
internal buzzers no longer require sounding. Any subsequent alarm will re-activate the internal buzzer and
require re-acknowledgment.
When multiple faults come into the system simultaneously due to broken cables, missing devices, system faults
etc. only one acknowledge function is required. This acknowledgment performs a "block acknowledge" of all
faults in the system.
A monitor device or detector which is set as tracking (Non-Latching) will also require acknowledgment when it
clears it's alarm state.
All events on the system must be acknowledged before a system reset can be performed.
S
CROLLING
As the LCD is only 2 lines, to scroll from one event to the next, simply press the "ACK NEXT" key.
D
ISPLAYING CURRENT
Once all alarms and faults have been acknowledged, the system maintains a list of all current alarms and faults
in the system which can be scrolled through individually, This can be done by simply pressing "ACK NEXT" to
step through the list. The list priority is Alarms in chronological order, then Faults & Isolates in Loop #, Device #
order. Continual scrolling will wrap around back to the beginning.
Once a new alarm occurs, the scrolling process is cleared and the cursor position is set back to the first event
(alarm) in the list.
R
ESETTING
As alarms on the system are generally latching, a System Reset is then required to return the panel back to its
normal condition. A system reset will clear all alarms from the system, and all faults. Isolated devices however
will remain isolated. To perform a system reset, press the "SYSTEM RESET" key once.

SOLATE
The "EXT BELL ISOL" button will isolate all outputs flagged with "Bell Isolate". This is to prevent the main bells
from ringing during routine testing.
Also once an alarm has been acknowledged, you can press the "EXT BELL ISOL" button, and the bells will
silence and remain silenced.
Note: If automatic bell cut-off is set, once the cut-off is initiated the EXT BELL ISOL will remain isolated until a
system reset. If bell cut-off is not set, the EXT BELL ISOL can be toggled on/off at any time by pressing the
button.
