Audio Loop Test - 2N Helios IP Configuration Manual

Configuration 2.3

Audio Loop Test

®
2N Helios IP allows you to perform periodical loudspeaker and microphone tests. For
this purpose, the in-built loudspeaker generates one or more short tones, which are
captured by the integrated microphone. If the tones are detected correct, the test is
successful. The test time is approximately 4s. If the test fails (due to some extreme
surrounding noise, e.g.), the test procedure is repeated in ten minutes. Follow the
®
most recent test results via your confirmation interface or with the aid of 2N Helios IP
Automation.
