Alarm Signals FT634aC => Major 4a/5a
Up to 3 alarms can be transmitted from an FT634aC to a Major 4a/5a. The FT634aC transmits
transmits any change of the alarm switching contacts to the major immediately. If no acknowledge-
ment is received, 3 repetitions are transmitted. If again no acknowledgement was received, trans-
mission is retried after a minute.
The Major displays each new alarm immediately. The operator has to acknowledge the alarms with
the #-button. All received alarms are displayed until they are acknowledged, even if they are not
active any more. In this case the present alarm status is displayed after the operator‘s acknow-
ledgement and also has to be acknowledged.
