Mimic Display Driver Ft2001-A1 - Siemens FS20 Planning Manual

5.10 Mimic display driver FT2001-A1

Building Technologies
Fire Safety
The mimic display driver FT2001-A1 is a parallel LED indication for the system-
wide signaling of events and is connected to the FDnet detector line. It has 48
LEDs that are installed on a ground plan panel.

Guidelines
● External power supply is possible with DC or AC.
● Mimic display drivers that are not fed by the ↑ detector line (separate power
supply) must be electrically isolated from the system voltage.
● Several floor repeater terminals and floor repeater displays, which are
connected to the same ↑ line card, must not be operated via an electrically
connected supply.
NOTICE
Influencing the earth fault monitoring
Faults
● Electrical isolation of the supply unit must be present for devices on the FDnet
that are fed separately (with the exception of the transponder).
● When an external supply unit is used, it must be taken into account that should
the external supply unit fail, the ↑ maximum current connection factor
increases significantly (line failure is possible).
● When power supply is ensured via the detector line, the high maximum current
connection factor (MK) must be taken into account.
● A maximum of 20 mimic display drivers can be connected per fire control
panel.
