Two external alarm indicators can be connected to each point detector.
On the FDnet, it is possible to connect external alarm indicator to any point
detector. The trigger for activating the alarm indicator can be programmed at the
control panel.
Instead of an optical alarm indicator that flashes in the event of an alarm, the
sounder base is provided with an acoustic alarm indicator.
The extended flashing behavior of the detectors FDOOT241-A and FDOOT241-
Ax is described in the 'Extended flashing behavior of the alarm indicators [➙ 40]'
chapter.

When operating the point detectors on the FDnet, individual detectors can be set
specifically to renovation mode on the fire control panel.
Select renovation mode if major work is being carried out in the room and large
volumes of dust or aerosols are being produced.
NOTICE
Changed settings
Limited alarm functions in renovation mode.
● In renovation mode, the neural fire detector and the heat detector only trigger
alarm when the temperature exceeds 80 °C for 20 seconds.
● The wide-spectrum smoke detector does not trigger an alarm in renovation
mode. All other functions continue to work as normal.
