Sub-stub on stub
Sub-stub on loop without line separation

Display
The line devices are displayed in the order of the loop/stub. On the branch to the
sub-stub, the line devices are displayed in the order of the sub-stub. The line
devices may be shown with incorrect symbols. The display shows the number of
the line device in brackets. E.g. [T003] for the third line device. In the case of the
red outlined devices, the internal alarm indicator flashes. If an external alarm
indicator is connected to these devices, the external alarm indicator also flashes.

'Config. sounder base' function
The 'Config Buzzers' function is not available in 'EL' operation mode.
The ’Config Buzzers’ function is only used for very old sounder bases
(manufactured prior to 2007). During this process, the outputs of the line detectors
briefly become active.

Starting up a line
When starting up a line, the detectors are generally not addressed again. The
affected detectors are re-addressed if there are conflicting addresses or
unaddressed devices.
