ALARM INDICATION
Page 10
Description
Each Attendant Console is equipped with three alarm lamps: MIN
(minor), MAJ (major) and CON (console). The minor alarm lamp, when
lit, indicates that the system has detected a malfunction which has not
seriously degraded the customer's service. A major alarm indicator is
caused by the system detecting a failure which affects the compjete
system operation and indicates that a failure transfer has taken place.
The console alarm is raised when a malfunction affecting the console
operation is detected. If the PBX system is equipped with an optional
reserve power supply, there are provisions for a "battery on" indicator.
This indicator may be wired to provide a Contact Monitor alarm to
alert the attendant that the system is on battery (i.e., AC power failure).
