9. Activating the power supply
9.2.3 Supply voltage to the room terminals
Activate 5 calls and 5 presence states for the ward which is to be checked. Use
the worst location, i.e. the most distant location from the power supply unit.
Test the voltage and determine the room terminal (ComTerminal Flamenco,
RoomTerminal Flamenco, ControlTerminal Flamenco or ControlTerminal with
doorplate Flamenco) with the lowest voltage. This point is considered as the
electric centre of the ring circuit. Here, the voltage differential to the first room
terminal as seen from the power supply unit must not be greater than 4 V.
If you should read a lower value (i.e. a drop of more than 4 V) the voltage drop
must be reduced by laying an additional cable from the power supply unit to the
electric centre - or double the 0 V lead - if it is available.

9.2.4 Check voltage for group bus OSYnet
If group bus OSYnet is correctly connected:
voltage between DH and DG and
voltage between DL and DG = approx. +2.5 V.
9.2.5 Check voltage for RAN
RAN voltage is o.k. when voltage between B (0V) and Y (RAN) is between
+8.8 V and +9 V DC.
If the voltage is outside of these parameters, these may be the reasons
If voltage between B (0V) and Y (RAN) = 0 V
a) Short circuit between B and Y
b) Wire Y (RAN) is not connected to the connection socket.
If voltage between B and Y = +12 V
a) Wire B (0V) is not connected at one of the RAN users.
b) One RAN user is defective.
