POLARA INX/IDX RETROFIT GUIDE
1.0 Warnings and Precautions
The following symbols indicate important safety warnings and precautions throughout this guide:
WARNING indicates that serious bodily harm or death may result from failure to adhere to the
precautions.
CAUTION indicates that damage to equipment may result if the instructions are not followed.
NOTE suggests optimal conditions and provides additional information.
1.1 Warranty Disclaimer
This guide will familiarize you with the features and installation of the Polara iNX pedestrian pushbutton as a
retrofit into a compatible Carmanah system. Failure to comply with the use, storage, maintenance, installation or
placement instructions detailed in this guide could void the warranty.
1.2 Standards
Perform all installation, wiring, grounding and maintenance in conformance with local building and electrical
codes. Adherence to the National Electrical Code (NEC) is mandatory to comply with any certification markings.
Non-adherence to code may void the warranty.
1.3 Safety and Usage Precautions
Use extreme caution when handling the batteries as they can generate hazardous short-circuit
currents. Remove all jewelry (bracelets, metal-strap watches, etc.) before entering the cabinet.
Before lifting any heavy or bulky equipment, ensure the load is secured so moving parts do not
shift, and that it can be lifted as far as needed without back strain or loss of grip. Installation may
require more than one person.
Ensure the equipment is not powered during installation and wiring of the system.
Recheck all completed wiring for proper polarity prior to energizing the system.

POLARA INX/IDX RETROFIT GUIDE
Changes or modifications to Carmanah equipment not expressly approved by Carmanah could
void both the user's authority to operate the equipment and the warranty.
All Carmanah traffic products use a constant-current LED output circuit. Not all traffic beacons
are compatible with this output. Please contact Carmanah for additional information and guidance
when adding or replacing beacons or other hardware.
Visit support.carmanah.com to download the complete product user manual for your specific
system.
Circuit boards are sensitive to electrostatic discharges (ESD). Care should be taken when
handling electronics to prevent discharges. Use of an ESD wrist strap and connection to cabinet
ground is recommended.
This guide is specific to retrofitting the Polara iNX/iDX with an applicable crosswalk system and is not a
replacement for the complete E/F/G Series product user manuals.

POLARA INX/IDX RETROFIT GUIDE
2.0 Introduction
2.1 About the Polara iNX
iNX is the next generation of crosswalk accessibility, wireless connectivity and communication. iNX is designed
for rectangular rapid flashing beacons (RRFB) and other approved flashing pedestrian crosswalk systems. It
replaces Model-X and sets a new standard for pedestrian crosswalks with more features such as Bluetooth® 5
providing more speed, range and app capabilities.
The iNX provides an instructional sign, a pushbutton with directional arrow for activating the flashing lights, a
voice message, and a yellow LED which flashes upon actuation and continues to flash while the beacons are
active.
2.2 Theory of Operation
Polara APS products for use on mid-block RRFB crosswalks use a control signal provided by the flash controller
to trigger the voice message. For Carmanah systems using the older “Model-X” series products, this control signal
was provided by the LED driver output. On newer Carmanah systems, using the new iNX/iDX products, this
control signal is provided by a dedicated digital output from the flash controller (EMS). Older Carmanah
controllers did not have this dedicated output and are not compatible with the iNX/iDX series pushbuttons. This
document describes the process for changing out the Carmanah controller to the new version across several
Carmanah product models.

POLARA INX/IDX RETROFIT GUIDE
4.1 General Notes
Refer to the applicable product user manual for more details at support.carmanah.com. Prior to installation, a
Solar Power Report must be provided to verify system sustainability with the addition of the iNX pushbutton. If you
have not received a solar power report, please contact Carmanah.
If your existing Energy Management System (EMS) is not running the firmware version 1.1.5.0 or greater, you will
require a new EMS as part of your retrofit kit.
Refer to the appropriate installation section based on your existing system model and pushbutton configuration.
Model iNX is equivalent to iDX in all aspects. Anywhere iNX is used in this manual, will apply to iDX also. Refer to
the respective full user manuals for additional user settings that may apply.
4.2 Onboard User Interface – Key Menu Items
Firmware Version:
Use the up/down arrows to navigate to the indicated menu item.
The Firmware Version menu item provides the current version of firmware in the EMS.
Firmware versions cannot be updated in the field.
Digital Output:
Use the up/down arrows to navigate to the indicated menu item. Hold Set to edit.
The Digital Output on the Energy Management System (EMS) must be set to ALL when used
with the iNX pushbutton on standard systems.
For systems with no installed fixture, the Digital Output must be set to nLED. This function
requires the EMS to have firmware version 1.1.5.0 or newer. Check 4.0 Supported Systems for
instructions on how to check the EMS Firmware Version.
