Connections For Dual Level Audibles - Dual Output Type - Siemens ST950 Handbook

4.15.5 Connections for Dual Level Audibles - Dual Output type

The recommended technique for connecting Dual Level Audibles is shown in
Figure 35. Link R40 must be cut. Although only 4 outputs are provided for each
type of Audible, the Module is capable of driving up to 8 Audibles at Quiet or 8
Audibles at Loud (for example, using a white terminal strip to expand the wire
connections).
If it is not required to disable all audibles at any time, a local wire link from
EN + to EN COM can be fitted instead of a connection to an I/O Card output.
Separate monitoring of Loud and Quiet outputs is provided by the Audible Driver
Module, but only one wire interconnecting the I/O Card 'Input Common' pins and
the Audible Driver Module 'Mon COM' pins is required.
Note that Special Conditioning is required to perform the monitoring.
