iN2 – iNavigator 2-Wire Push Button StationThe iN2 Navigator 2-Wire Push Button Station (iN2 PBS) is the pedestrian interface to the iNavigator Accessible Pedestrian System. Main components of a system consists of a Control Unit (P/N: iCCU-S or iCCU-C) and two or more Push Button Stations. The iN2 is an MUTCD compliant PBS, providing valuable information and cues via both a vibrating arrow button and audible sounds, making the intersection accessible for all pedestrians. All sounds emanate from both the front and the back of the unit. A sunlight-visible red LED latches “ON” along with a tactile feedback “bounce” to confirm the button has been pushed. The vandal-resistant designed iN2 PBS includes the body which houses the ADA compliant push button (shown), a faceplate (sign), and mounting hardware.

By interfacing with the Control Unit that installs in the Traffic Signal Control Cabinet, the iN2 PBS can provide the following standard features:

• Operates over a single pair of wires• All push button stations wired in parallel, individually assignable to any phase• 16 buttons can operate with a single Control Unit*• All sounds are synchronized• 4 Locate Tone selectable options• 13 Walk Sound selectable options, 3 of them custom options• 7 Clearance Sound selectable options• Walk, Clearance and Don’t Walk sounds adjust automatically to ambient• Separate ambient response settings for Locate Tone (for quiet ambient conditions)• Most sounds have independent Min/Max settable limits• Button vibrates during Walk• Button push confirmed by latching LED, tactile bounce, and audible “wait” sound• Extended button push can boost volume for next Walk and Clearance • Direction of travel message with extended button push, capable• Extended Push Priority: Mutes all but selected crosswalk, capable• Extended Push Activation Settings: 0-6 second range, .5 second increments• Beaconing and Ping Pong features available• Select audio messages, change settings, and perform firmware updates wirelessly

using iOS devices, or a Windows PC with Polara’s Bluetooth Dongle (P/N: iN-DGL)• Built in Health/Event logging feature, up to 300 events• False Walk Detection: Four independent checks• External Speaker-Option at time of order• External Button Input for bike lane, horses, etc.• Warranty: 3 year limited

An iN2 PBS can operate as an iN3 PBS (Ped-Head Based System). It comes with a 3-position terminal block (see figure next page) to connect to a Ped-Head Control Unit. See iN3 Quick Start Guide for more informtaion/instructions.

iCCU-S – iNTELLIGENT CENTRAL CONTROL UNIT FOR SHELF MOUNTThe iCCU-S is designed to work in all style cabinets as the intelligent control unit for Polara’s iN2 accessible push button stations (PBS) when the 50 pin harness is used. The system includes a small interconnect panel (PN: iN2-ICB) to allow connection to 16+ PBSs. Each iN2 PBS connects with two wires. All PBS connect in parallel and do not have a polarity requirement.

This model also supports SDLC communication in TS1 and TS2 cabinets when a TS2 controller operating in TS2 mode, with an MMU, is utilized (There must be an MMU). If just PED Walk / Don’t Walk interval information is communicated by SDLC, the 50 pin harness is still needed. If both PED interval information and call placements are communicated, the 50 pin harness is not needed, unless preemption is also required.

The iCCU-S front panel includes a backlit LCD for displaying system status information. Front panel buttons are used during setup, placing test calls, and to enable Wi-Fi. All setup functions can be performed via Ethernet or Wi-Fi using a PC. Setup is also supported using an iPhone or iPad via Wi-Fi. In addition, configuration via Bluetooth is supported by pairing with any connected iN2 PBS using a PC, iPhone, or iPad. All of the connection options provide full access to setup and configuration options of both the iCCU-S and all connected iN2 PBSs. Polara provides free apps for both Windows PCs (Win 7+) and iOS (8.0+) devices.

Multiple configurations are supported, with the ability to change operational features based on time of day. General purpose inputs are available for options such as a voice message on emergency vehicle preemption. The system has internal conflict monitoring and health log data capture that is both downloadable and contains extensive status/fault reporting. Remote Monitoring can be done over Ethernet.

Field Wire Recommendations for iNavigator 2-Wire Accessible Pedestrian Signals (APS)

Because Polara’s 2-Wire APS buttons transmit power and data over a single pair of wires, it is very important that the wire be of good quality, the right size, and without stretched sections, kinks, splices, or damaged insulation.

Stretched sections, kinks and splices can cause high impedance points that disrupt the transmission of data.

Damaged or cracked insulation can cause stray voltages, which generates noise that impedes data transmission, especially if the wires are next to high voltage wires, or in conduit with water/moisture.

For optimum performance and to help ensure successful installation and operation, Polara recommends the following.

1. 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 be acceptable.

2. If the distance from the cabinet to the farthest APS button is less than 300’, #14 AWG solid or stranded wire should be fine. If the distance is greater than 300’, #12 stranded wire should be used.

3. If dedicated pairs cannot be pulled/provided, at a minimum a single pair daisy chained to two buttons on a corner of an intersection typically works. A 3-wire cable per corner with the common wire shared by the two buttons on the corner also typically works, but with either option in place of dedicated pairs, you may encounter data transmission reliability issues.

4. A common wire for 120 VAC lights must never be used as the button common.

Our 2-Wire APS has been successfully installed on 100,000+ intersections. We know that many of these intersections had multi-conductor cables pulled to each pole, and conductors in these cables were used for our buttons. Because high voltage is on some of the conductors in these cables, there is a greater chance for noise that can affect the data transmission on the wires used for the buttons, especially over long runs/distances. The longer the distance to the farthest button, the greater the chance of data transmission problems. Very few installations have been unsuccessful. As long as the conductors are without stretched sections, kinks, splices, or damaged insulation, and the conductors are of good quality, a successful installation can usually be achieved, even when providing dedicated pairs of wires to each button is not possible.

In the very rare instances where a 2-Wire installation cannot be made to work, installation of 3-wire units is the next best option. Often times when just the farthest button will not operate correctly, just that button (or crosswalk) is used as a 3-Wire.
