False Alarms or Errors
Possible Causes
A device that is to be assigned to a radio
group is no longer in connection mode
Connection mode is active for 10 minutes.
To reactivate connection mode after this,
see “Repeat Connection Attempts”
Devices of the radio group to which further
alarms are to be assigned are not, or are no
longer, in connection mode.
Connection mode is active for 10 minutes.
To reactivate connection mode after this,
see “Extending the Existing Radio Group/
Re-entering Connection Mode”
The distance between two alarms in connec-
tion mode is too great; no connection
is possible
Reduce distance between the alarms; to do so,
add an extra alarm
One alarm will not connect to the radio group
Restore alarm to factory settings, see “Restore
Factory Settings”; enter connection mode
