7.7 Replacing the battery pack

Building Technologies
Fire Safety
Each radio device stores its contact data in the event of an interruption in the
power supply lasting two minutes. The stored contact data enables the radio
device to reintegrate itself into the radio network without delay and without any
problems. If the power supply for a radio device is interrupted for more than two
minutes, the contact data will be lost and this radio device will not be detected. If
this happens to multiple radio devices at the same time, this means there is a
fault in the radio cell.
Do not interrupt the power supply for longer than 2 minutes.
l
Do not interrupt the power supply to multiple radio devices simultaneously.
l
Replace the battery pack for one radio device as described below before
replacing the battery pack for the next radio device. This will prevent mix-ups
and will ensure the devices can be reintegrated into the radio cell without any
problems.
