Campbell Company Type of APS Pushbutton integrated
iQ APS
Pedhead mounted speaker optional or available.
The
Campbell IQ APS has a large, convex pushbutton with a small indentation
in the center so that it can be actuated with a head-stick used
by a person having no limb dexterity. The large arrow above the
pushbutton is vibrotactile.
Campbell APS H-frame
version is used in some north-western cities so that the push-button
can be mounted on the side of the pole away from the street. However,
the H-frame blocks the sound from the side of the APS, making it less
usable for homing in on the locator tone.

signal. Driver unit may also be mounted outside the pedhead in a separate
enclosure if desired.
4 pair #24 stranded wire is run from pedhead to pushbutton unit.
Microphone for automatic volume adjustment is mounted in a 3 in.
diameter parabolic bowl (sound dish) used to gather sound samples
and direct them to the microphone used in adjusting the ambient gain
control.

After reaching the pushbutton and checking the arrow alignment to
ascertain that the arrow is aligned parallel to the crosswalk they
want to use, indicating that it is the correct pushbutton, they will
push the button and return to realign to cross the intersection.
They may find it necessary to repeat the process if they don't feel
they are realigned appropriately when the pedestrian phase begins.
As they cross the street, they will begin listening for the pushbutton
locator tone for the APS on the opposite side of the street and may
home in on it as they reach the last lane of traffic.
