The PDM-1 Phone-Doorbell Mute Plate is used with RTI Audio distribution systems (Models: AD-8x/AD-4x/AD-8/AD-4) to provide a connection point for phone and doorbell systems. When an incoming call is received or a doorbell is rung, the voltage from these systems is passed to the audio distribution system and will temporarily mute the audio. The PDM-1 is wall mounted in a standard single gang electrical box and uses a Decora style wall plate (not included).

Features:

• Provides a convenient connection for phone and doorbell systems.
• An incoming call or doorbell generates a voltage which is passed to the RTI audio distribution system to mute the audio temporarily.
• A Phoenix connector will accept up to two AC or DC voltages from two different doorbell chimes.
• An RJ11 jack will accept a single phone line.
• Mounts into single gang electrical box and uses Decora style wall plate (not included).
• No power supply required for operation
