Intent/flag available to trigger TC75 barcode scanner

Was wondering if there was an existing intent to trigger the device Barcode scanner. I simply want the intent to trigger the device scanner process (flash using the scanner and make the beep sound). The purpose is to performance test an app that utilises the scanner. At the moment I have an Intent that overrides the scanner, I'd prefer to trigger the scanner functionality in code whilst using the scanner override process to receive the scan message at the same time.

Any help or response will be highly appreciated. Thanks in advance.
