control panel documentation.
- Document 009052 applies to control panels FC20xx.
- Document A6V10210416 applies to control panels FC72x.
2. Switch the detector line off.
LED (H2) is not flashing.
3. Set the radio gateway to maintenance mode.
- Press and hold button (S1) for at least 2 seconds until LED (H2) flashes.
The radio gateway and its radio cell are in maintenance mode.
LED (H2) flashes at 1-second intervals.
The radio devices can now be logged off and on.
4. Remove the old radio device from the base or housing.
The internal alarm indicator flashes briefly at 2-second intervals.
5. Remove the battery pack from the radio device.
6. Store, transport, and dispose of the battery pack in accordance with local
regulations and laws. See also chapter 'Basic principles for replacing the

The radio gateway registers the old radio device as missing after a
maximum of 5 minutes.
LED (H4) flashes.
7. Remove the adhesive label from the radio device and use it to mark the
installation location on the device location plan.
8. Connect the power supply for the radio device.
The internal alarm indicator of the radio device flashes.
If it flashes red, this indicates the factory settings.
If it flashes green, this indicates that the radio device has already been
logged on to a radio gateway and needs to be set to the factory settings.
9. To set a radio device to the factory settings, press the 'new' button on the radio
device until the internal alarm indicator flashes red.
The radio device is set to the factory settings.

The search for the radio network starts. During the search, the internal
alarm indicator briefly flashes green twice, at an interval of 2 seconds.
Once the radio device has successfully been logged on to the radio
gateway, the network search stops and the internal alarm indicator goes
out.

passed, briefly remove the radio device from the base/housing and then re-
insert it.
The search for the radio network starts again.
