How to silence a loud intercom and change the ringtone?

The discussion addresses how to reduce the loud volume of an intercom and change its ringtone. The original intercom model lacks a factory mute option or volume control. A practical temporary solution suggested is partially covering the earpiece opening with tape to lower the sound. For a permanent fix, replacing the intercom with a model that includes volume control and mute functionality is recommended. A specific replacement model with adjustable ring volume was identified. Additionally, the possibility of enabling a sound notification when a code is entered on the external panel was explored. This feature is controlled programmatically via the intercom’s firmware and can be activated by following a specific procedure outlined in the manual (function F104). Wiring details were discussed, noting four wires (green, blue, brown, white) with blue connected to F- and green to +, while brown and white remain unused. The solution avoids additional hardware connections for code entry confirmation sounds. The discussion also includes requests for photos of the intercom and external panel to assist with identification and advice.
