TLPI Signal Node
Mounting Location
Mount TLPI Signal Node to the inside
for plastic pedestrian signal heads.
Mount outside if the ped head is made
of aluminum or steel.

Cabinet
Utilizes the existing field wires from cabinet
to pedestrian push buttons to place calls
NOT polarity dependent
Note: For NEW intersection installations, in the absence of
city or other local specifications, PedSafety recommends
IMSA 14-gauge (loop detector wire).
