7.1 Changing batteries on the FDCW221
The battery in the radio gateway must be replaced when a battery fault for the
radio gateway appears on the control panel. The detector line must not be
switched off during the battery fault otherwise the service life of the radio detector
batteries will be reduced significantly!

detector line without any interruptions.

1. Unlock the cover of the radio gateway on the face side using a pin.
2. Pull off the cover of the radio gateway.
3. Replace the battery.
4. Snap the cover of the radio gateway back into the back box.
It may take up to 30
minutes for the battery fault
message to disappear from the

message only disappears if the newly inserted battery has sufficient voltage.
All fault messages are updated if you do the following:

2. Remove the battery.
3. Insert the battery.
