5.4.08 Audio Test
®
The 2N Helios IP intercoms allow you to perform periodical tests of the integrated
speaker and microphone. For the test purpose, the integrated speaker generates one
or more short beeps. The integrated microphone receives the generated tone and the
test is successful if the tone is detected correctly. The test takes approximately 4
seconds. If the test fails (which may be due to an extreme surrounding noise level,
e.g.), a new test is carried out in 10 minutes. The result of the last test can be
®
displayed in the intercom confirmation interface or processed by the 2N Helios IP
Automation.
Note
The audio test is available with the Gold or Enhanced Audio licence only.
