17.5.7
External Speaker Option
This option is only available on special ordered units with part number suffix
–ES and must be specified at time of
ordering.
When enabled, all walk and clearance sounds emanate from an external speaker and all other sounds emanate from the
internal speaker.
Factory Default: Disabled
17.5.8
Double Walk
This setting enables a unit to automatically generate a ped call and enable sound for two Walk and Clearance intervals. A
second ped call is generated after the end of the first Walk interval enabling a second Walk interval to occur. This is
typically used for crossings which have an island without a pushbutton present in order to prevent the possibility of a
stranded pedestrian.
The available options are: No, Yes
Factory Default: No
17.5.9
Limit Push Recall
This option is only for use when Walk Sound Trigger is set to Extended Push and Sound/Vibrate Re-Trigger is set to New
Walk. This option limits the ped call re-trigger to only occur when an extended push occurs during the Walk interval. If only
a standard push occurs, no ped call will occur at the end of Walk.
An automatic call placed by the PBS at the end of Walk should only happen following an Extended Push during Walk.
During Walk, only an Extended Push should latch the Pilot LED. During Walk, only an external button call for Extended
Push duration should latch the Pilot LED.
An Extended Push which starts during Don’t Walk and finishes during Walk
should have the same result as an Extended Push completely within Walk.
The available options are: No, Yes
Factory Default: No
