OUTLINES
Front Panel Outline
1. Both halves of the POWER indicator (green) are on at all times to indicate the presence of DC and in-
terruptable AC power.
2. The SERVICE indicator (white) is on only when the CPU is not functioning.
3. The TROUBLE indicator (yellow) is on when an uncorrected malfunction exists. Key in the “TRO”
command to obtain a listing of all supervisory fault (trouble) messages. See the Transponder Outline
for procedures to insert a trouble (SUPR FAULT) when one is desired.
4. The SECURITY indicator (yellow) is on when a priority 2 alarm is set (tripped). Key in the “ALA” com-
mand to obtain a listing of all set (tripped) alarms. The transponder specification sheets will list the
priority level for each alarm. When a priority 2 alarm is desired, see the Transponder Outline for the
procedure to initiate the alarm.
CAUTION:
Building personnel and proper authorities (i.e., Police/Fire Department) must be notified
prior to initiating an alarm.
5. The ALARM indicator (red) is on when a priority 1 alarm is set. Key in the “ALA” command to obtain
a listing of all set alarms. The transponder specification sheets will list the priority level for each alarm.
Refer to the Transponder Outline for the procedure to initiate an alarm.
6. The tone device sounds when any of the first three indicators (ALARM, SECURITY or TROUBLE) is
blinking or if the SERVICE indicator is on. The first three indicators will blink from the time a con-
dition is changed until it is acknowledged. All alarms and troubles must be acknowledged to silence
the tone device. The operation of the tone device can be checked by initiating an alarm or a trouble.
7. The PAPER ADVance push button is pressed to make the printer feed paper. (If system is equipped
with acentronics Printer, the front panel will not have this switch.)
8. The ACKnowledge push button is pressed to indicate that a changed condition is being recognized.
Pressing the ACK push button when one (or more) of the first three indicators is blinking should pro-
duce an acknowledge message. This message is preceded by “ACK” and gives the status of the alarm
or trouble message that was acknowledged. Each change in alarm or trouble status must be acknowl-
edged individually.
