4.15.4 Audible Driver Module - Dual Output type

In order to drive audible indicators, an Audible Driver Module Kit of Parts (KOP) is
required – Siemens part number 667/1/32955/000. The module is powered from
the phase Green of the relevant pedestrian phase output of the LSLS card and
provides a regulated 12V DC to the audible indicators.
The module can be connected to an I/O card to allow operation to be inhibited (for
example at night), and to allow switching from Loud to Quiet audible indicators.
The Audible Driver Module will operate at both dim and bright lamp voltages.
The updated Audible Driver Module provides 4 outputs for Loud indicators and 4
outputs for Quiet indicators. A link position is normally fitted to connect these
outputs together, giving 8 audible indicator outputs which are energised whether
Loud or Quiet is selected (this gives full compatibility to the previous version of the
Module). Cutting the output link allows separate control of Loud and Quiet outputs.
