Multi-sounder with a fixed signalling tone:
If several sounders are being operated simultaneously with the same signalling tone, it
may be a good idea to synchronise the signalling tones, i.e. to make sure the signalling
tones of all the sounders sound for an equally long period of time. This is only possible with
the signalling tones for which “Sync” has been ticked off in the table “Signalling tone
description”. To enable synchronisation, the terminals 3 of all the sounders, the terminals 4
of all the sounders and the terminals 5 of all the sounders must be interconnected.
To select a fixed signalling tone (Stage 0, Stage 1, Stage 2 or Stage 3) from the set
signalling tone group, the control inputs of one of the sounders must be connected
accordingly. This may be prepared at this stage, or after the sounder has been mounted.
Perform the setting of a fixed signalling tone as follows:
Stage 0
No connections
Stage 1
Connect terminal 3 and terminal 4 using a jumper
Stage 2
Connect terminal 4 and terminal 5 using a jumper
Stage 3
Not a useful setting in this application, as synchronisation is not possible
when terminals 3, 4 and 5 are interconnected.
Multi-sounder with variable signalling tone:
As „Multi-sounder with a fixed signalling tone“, except that the signalling tone may be
chosen via floating contacts of a control device.
Select a signalling tone via floating contacts k1 and k2 as follows:
Stage 0
Both contacts open
Stage 1
Contact k1 closed, contact k2 open
Stage 2
Contact k1 open, contact k2 closed
Stage
3
Both contacts closed. Please note that for this selection a
synchronisation of the signalling tones is not possible.
