Tone Test (Zenitel Connect Pro)

The Tone Test feature is a self‑test that checks whether an intercom’s microphone and loudspeaker are functioning correctly.

The intercom plays a test tone through its loudspeaker and uses the built‑in microphone to measure the sound pressure level. If the initial test fails, the test will repeat itself three times with an increased volume every time. If the microphone successfully detects the tone, the test passes; if not, it fails.

The Tone Test can be started in multiple ways:

• From the Zenitel Connect Pro web interface
• Via automation from Node-Red
• From Zenitel Remote Monitoring and Management (RMM)
• From 3rd party applications such as:
  • Zenitel Call Handler in Milestone XProtect

Devices that do not have a microphone or loudspeaker will always fail the tone test. Devices where the microphone cannot reliably pick up sound from the loudspeaker — such as handset‑only units or stations using gooseneck or handheld microphones — may also fail the test.

Tone Test - triggered from Node-RED

The Zenitel Action node Zenitel Tone Test can be used to start the tone test on an individual device or on a group of devices.

The Zenitel Event node Zenitel Extended State can be used to read the result of the Tone Test.

Logging of Tone Test results

Tone Test results are reported to the the System Log.

3rd Party Applications

By means of the Zenitel Link a 3rd party system can use a WAMP message to start the Tone Test and a WAMP subscription to receive the result.

• The URI to start the tone test is: com.zenitel.system.devices.test.tone.post
• And the URI for the subscription to receive the results is: com.zenitel.system.device.extended_status

Milestone XProtect

The interface between Zenitel Connect Pro and Milestone XProtect allows operators to manually initiate a tone test on selected intercom devices.
