Why is the speech message not working on the Polara iNX/iDX push button?

This article details the troubleshooting steps to be taken to troubleshoot a Polara iNX/iDX speech message issue.

Product applicability

The following products are discussed in this article:

  • E Series: R920-E and R820-E

  • G Series: SC315-G and R820-G

Systems equipped with the Polara iNX/iDX push button only.

See the checklist below for buttons that won't play the speech message:

  1. Firmware is out of date
Follow the instructions in the Polara Field Service app under the Update Firmware menu. Ensure you are running version 1.1.0 or newer.
  1. Settings are incorrect in the Polara Field Service app

Set Speech Message Start Delay to 0s.

Set LED Flash Behavior to Rapid Flash (for RRFBs) or Simple On/Off (for beacons/LED signs)

  1. Speech message is turned off in the Polara Field Service app
Assign the speech message selection accordingly in the Polara Field Service app.
  1. Button wiring is incorrect
For button wiring please see our article here.
  1. Digital Output setting is incorrect
Scroll to the OUTP setting on the Carmanah Energy Management System (EMS) and ensure it is set to ALL. If it is set to NITE then the message will only work at night.
  1. LED fault on Carmanah EMS
Confirm there is no LED "open" or "short" fault displayed on the Carmanah EMS. Power cycle the system and try again. Check LED wiring.
  1. Speech message volume is low in the Polara Field Service app
Adjust the Speech Message Volume settings in the Polara Field Service app.

If your system does not have an LED load connected to it (RRFB, LED sign, circular beacon) you will need to set the OUTP setting to NLED. See our article here for more information.

The checklist above assumes you have a working system with proper system voltage.

If a firmware update is available in Polara Field Service app it is best to update all buttons at the crossing. Version 1.1.0 introduces the new standard speech message as per of MUTCD 11th Edition .
