The Audible Driver Module is connected as shown in Figure 29 below and is
mounted on the rear panel in the controller cabinet using the screws supplied in the
KOP.
Where more than 8 audible units need to be driven simultaneously, it is acceptable
to connect up to 4 Audible Driver Modules in parallel to each LSLS output, giving up
to 32 audible units per LSLS output.
In order for the Audible Driver Module to operate, the two “Inhibit +” and “Inhibit –”
connections on the Audible Driver Module must be shorted together. Where it is
desired to switch off the Audible Driver at certain times of the day, the Inhibit
connections can be connected to the ‘Common’ and ‘Normally Open’ connections of
an I/O card.
Where two Audible Driver Modules are connected in parallel, it is
important that the “INH -” connections are paralleled and the “INH +”
connections are paralleled. Do NOT connect “INH +” of one Audible
Driver Module to “INH -” of another.
Tactiles and/or Audibles must not be paralleled with Pedestrian Greens if
the Pedestrian Green is to be lamp-monitored.
A maximum of 4 Tactile Units and 1 Audible Driver Module (8 sounders) or 2 Tactile
Units and 2 Audible Drivers (16 sounders) can be simultaneously driven from one
LSLS output.
