400A Base Station Installation
The 400A Base Station mounts to a 9x12 cast pedestrian station with 2ea. ¼” - 20 x 1” PHP
screws. Align the Base Station so the tactile arrow is pointing directly to the crossing
destination. Some installations do not call out arrow directions and require installation in the
field. The tactile arrow is field selectable (left or right) requiring two security screws and a
security driver. Campbell Company provides this hardware packet only when specified at the
time of purchase. Contact Campbell Company Technical Support if a security bit is needed for
tactile arrow modification.
Note: THE PEDESTRIAN RELIES ON THIS INFORMATION TO CROSS SAFELY.
Install Signal Power Interface Board (SPI)
1. Disconnect the power to the Pedestrian Signal Head prior to installing the SPI.
2. Open the Pedestrian Signal Head Display and identify a ¼-20 tapped hole (see Table 1)
on the back surface wall to place the SPI. A ¼-20 x 2.0” FHP is used to screw through
the SPI into the pedestrian display.
