2. Description
2.1 iNX Mid-Block Crossing Push Button Station
The iNX is a mid-block crossing push button station (PBS). These PBSs are typically used in pairs, mounted on poles at
each end of a mid-block crossing. The iNX push button station is designed for Rectangular Rapid Flashing Beacons
(RRFB) & other approved Flashing Pedestrian Crosswalk Systems.
The system consists of a 9”x12” instructional sign, a push button with directional arrow (bidirectional and blank buttons
also available) for activating the flashing lights, a voice message, and one yellow LED above the push button that flashes
when the street warning lights are flashing.
The iNX uses the same rugged housing as Polara’s “iNS” iNavigator. In addition to the push button, the iNX contains a
speaker, a 10-watt RMS audio amplifier, a noise monitoring microphone for auto volume control, and LED indication.
The iNX operates off of the warning light system control unit via six wire connections (see pages 6-7). The iNX has the
same Bluetooth configuration interface as the “iNS” iNavigator, which is used to select audio messages, change settings,
and download firmware updates.
The unit is supplied with mounting hardware and installation instructions. This unit is not compatible with XAVCU
controllers.

3. Push Button Station Installation
NOTE: Prior to installation power should be removed from the warning light system control unit to avoid damage from
accidental shorts to the aluminum pole.
INSTALLATION NOTE: You MUST install the Polara Field Service App to complete this installation. Polara
suggest downloading it at this time.
- All of the available setup and maintenance procedures MUST be performed using a compatible iOS device or
Android device. 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.
3.1 iNX PBS
The iNX 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 a mid-block crossing with existing
buttons, remove existing buttons. 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. 6.25” below the lower mounting hole. If not, you need to figure
out a way to achieve more wire length.
The iNX PBS is a modular device consisting of a backplate, electronics module, speaker module, arrow button diaphragm,
button cover, sign, and sign backplate. 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 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, establishing a connection to Earth ground and must be re-installed.
Verify the arrow on PBS module, if present, is oriented toward the associated crosswalk. If necessary, the button
diaphragm assembly may be taken 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 back plate.
Position back plate on pole at correct height and orientation so arrow will point to ending of crosswalk on the opposite side
of the street. Orientation is very important because a blind person uses the arrow and face of the sign to orient
themselves to the direction of travel. Mark mounting bolt locations if existing holes not correctly located. MUTCD max.
height is 48”. Typical recommended height is 42”, but can be lower. Drill and tap ¼-20 bolt holes and wire access hole (if
necessary). Route a 6-wire cable from the warning light system control unit to the PBS. The cable should be supplied by
the customer/installer.
Position the backplate against the pole and route the wires forward near the bottom end of the backplate. Position the wire
such that 3 or 4 inches of wire is available at the bottom of the backplate.
Attach the backplate to the pole using the provided ¼-20 bolts with washers.
Re-install the electronics/speaker modules. Re-install the sign with the sign backplate, securing the PBS Module in place
before wiring. Re-install EARTH ground connection screw to location between terminal blocks.
Connect the six wires from the warning light system control unit to the PBS’ terminal block. Make sure the wiring matches
at both ends according to the LIGHTS, BUTTON, PWR, and GND labels at the terminals. See figure below.

For programming and configuration of the iNX PBS, launch the Polara Field Service App and complete the sections of this
User Manual listed below:
Section 7.4 - Setting Device Password
Section 7.5 –Assigning a Name to PBS
Section 7.6 –Setting PBS Time and Date
The iNX PBS is now ready to use. If you wish to customize more available settings, please review Section 7.3.
3.2 Connecting an External Button
The iNX PBS supports connection of an external button such as the Polara Bulldog BDSP-014 or the BDL3. Pressing the
external button is equivalent to pressing the iNX button, but without the associated push confirmation sound. The button
wire pair should connect to the large terminal block labeled “BUTTON” with one wire to each terminal. Polarity is not
important. The external button would be connected in parallel with the button wires to the warning light system control
unit.

6.3.5.3 LED Flash Behavior
The iNX’s LED Flash behavior can be programmed to either track the LIGHTS INPUT signal, such that whatever pattern
of High and Low voltages is present on the input will be reflected on the LED, or it can be programmed to play a
predefined pattern when the input goes HIGH, following a button press. Note, this LED flash behavior begins upon the unit
detecting a high signal at the LIGHTS INPUT only after the button is pressed. It lasts until the LIGHTS INPUT detects a
low signal lasting at least 600ms.
1. Track LIGHTS INPUT signal:
The LED output will mimic the signal present on the LIGHTS INPUT. When the input is High, the LED will be on.
When the input is Low, the LED will be off. This setting is commonly used with an RRFB.
2. Play predefined pattern:
Upon detecting a High input, the iNX will play a predefined pattern so long as the LIGHTS INPUT is held High.
The options for this mode are as follows:
A. Solid LED On
In this mode, the LED stays on as long as the LIGHTS input is held High.
B. Simple On-Off
In this mode, the LED turns on for 500ms and then off for 500ms and repeats, as long as the LIGHTS input is
held High.
C. Rapid Flash
In this mode, the LED follows this sequence as long as the LIGHTS input is held High:
ON for 50ms →OFF for 150ms →ON for 50ms →OFF for 150ms →ON for 50ms →OFF for 50ms →ON
for 50ms →OFF for 250ms
