3.13.1 Single Pedestrian Audible Drivers and Monitoring Audible Driver

The ELV Audible Driver Module supplies the power to drive the Audible indicators, directly from
the Green Man output of the LSLS card. The ST750ELV running standard pedestrian
configurations provides one dedicated audible drive output per pedestrian phase. The ST750ELV
includes circuitry to directly drive audible indicators on the first pedestrian phase only.
Connections for these audible indicators are provided on rows 1 to 5, marked AUD1 on the
Backplane terminations and shown in Figure 50.
Alternative connections are provided for loud and quiet audible drives, together with a common
return. Special Conditioning will provide any necessary transitions.
Full connections details for this option should be sought from handbook 667/HB/32750/000.
