ALARM
If a fault occurs in the exchange, the ALM lamp flashes and
an alarm field in the bottom row of the display shows 2,3 or
4. The number indicates the degree of seriousness.
2 = Requires action within one week
3 = Requires immediate action during normal working hours
4 = Demands immediate action at all times
Use the following procedure to acknowledge the alarm:
Press
The flashing ALM lamp changes to a steady light.
The purpose with the acknowledgement of the alarm is to
avoid other operators from reporting the alarm.
After acknowledgement, you must report the alarm to main-
tenance, stating the alarm class as above.
The alarm indication with steady light remains until mainte-
nance staff have eliminated the fault and erased the alarm
from the maintenance terminal.
When SERV lights in the bottom row of the display field the
maintenance staff are working in the exchange room.
