iNS2 PBS Installation Procedure
Note: For optimum functionality Polara recommends:
•
A dedicated cable with two (or three for a spare) conductors run from the Traffic Cabinet to each APS
button. We recommend IMSA 50-2 cable. This cable includes a shield, but connecting the shield is not
required/recommended. Twisted pair is not required, but would be acceptable. Cable similar to 50-2 without
the shield and drain wire would also be acceptable.
•
If the distance from the cabinet to the farthest APS button is less tha
n 300’, #14 AWG solid or stranded
conductors/wire should be fine. If the distance is greater than 300’, #12 AWG stranded conductors/wire
should be used.
•
If dedicated pairs cannot be pulled/provided to each button, at a minimum a single pair daisy chained to
two buttons on a corner of an intersection typically will work. A 3-wire cable per corner with the common
wire shared by two buttons on the corner will also typically work, but with either option in place of
dedicated pairs, you may encounter data transmission issues.
•
A common wire for 120 VAC lights must never be used as the button common.
•
For further Wiring information refer to “Polara iNavigator Field Recommendations” at www.polara.com
under “Installation and Operation Manuals” sections.
INSTALLATION NOTE: To complete this installation, you MUST install the Polara Field Service App on your iOS
or Android device or the Intelligent Config PC App on a laptop (with the Polara iN-DGL Bluetooth dongle for
connections to the PBS). Polara suggests downloading it at this time. If using an Android device, please refer to
the “iN2 Polara FS Android Application Manual” when using the FS App.
-
All of the available setup and maintenance procedures MUST be performed using a compatible iOS device or
Android device or PC with iN-DGL. Your device must have iOS version 9.0 or higher or Android 5.0 (Lollipop) or
higher.
-
The Polara FS App will need to be installed on your device. It is available on the Apple App Store and the Google
Play Store. The Intelligent Config PC App is available at www.polara.com.

Plan PBS (push button station) locations if they have preprogrammed special messages. If special messages are not
used, or will be programmed once each PBS is installed, proceed to next step.
The iNS2 PBS must be mounted only in the upright orientation with the connection terminals at the bottom, any
other mounting orientation will void the warranty.
If retrofitting these buttons on an intersection with existing buttons,
remove existing buttons. Typical push button frames have the wire exit hole in the pole directly behind the center of the
button (at least
3.5” below lower mounting hole). Because our PBS requires the wires to reach the bottom of the unit,
verify 8” of wire extends beyond wire exit hole in pole. If enough wire is not available, evaluate whether a new, lower wire
exit hole that would line up with the terminal block access point in the bottom of the PBS would provide adequate wire
length. If yes, drill and reroute wires, the optimal position of this hole is approx. 6.5” below the lower mounting hole. If not,
you need to figure out a way to achieve more wire length.
The iNS2 PBS is a modular device consisting of a backplate, electronics module, speaker module, arrow button
diaphragm, button cover, sign, and optional sign backplate (for larger signs). The PBS is shipped partially assembled to
secure it during transport. To prepare for mounting, remove 3 screws from the lower cover. Remove all screws securing
the sign and sign backplate if present. Remove EARTH GND (ground) screw located between the two terminal blocks at
the bottom of the unit. Store this screw in a safe place, it ensures the unit is grounded to the pole and must be re-installed.
Verify the arrow on PBS module is oriented toward the associated crosswalk. If necessary, the button diaphragm
assembly may be pulled off and rotated as needed. Secure the button diaphragm in the correct orientation by tightening
the two retaining screws with a Phillips-head screwdriver.
Please use caution, as the metal button diaphragm is
sharp.
Remove the electronics module and speaker module together from the backplate.
