Possible applications
Single sounder with a fixed signalling tone:
You have selected a signalling tone group according to the procedure described earlier in
this manual. To select a fixed signalling tone (Stage 0, Stage 1, Stage 2 or Stage 3) from
the signalling tone group, the control inputs must be connected accordingly. The control
inputs are the terminals 3, 4 and 5, located in the sounder’s electrical enclosure. Place the
sounder with the horn opening resting on a level surface, loosen the 6 screws of the
electrical enclosure lid and remove the lid.
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
Connect terminals 3, 4 and 5 using a jumper.
Single sounder with variable signalling tone:
If there is a requirement for the ability to select the individual signalling tones of a signalling
tone group (Stage 0, Stage 1, Stage 2 or Stage 3) during operation, terminals 3, 4 and 5
must be connected accordingly to the floating contacts of a control device. This may be
prepared at this stage, or after the sounder has been mounted.
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
