WIRING FOR MUTE INPUT
The back panel of the AD-4x has a 3.5mm non-shorting stereo connector input
labeled “Mute”. This is designed to be used with the PDM-1 Phone-Doorbell-
Mute module. When the PDM-1 is connected, the system will temporarily mute
when the phone or doorbell rings.
Doorbell
The back of PDM-1 will accept up to two AC or DC voltages from two different
doorbell chimes. This connection is done with two conductor wire from the
terminals on the doorbell chime to the Doorbell A or Doorbell B inputs on the
back of the PDM-1, Polarity is not important for this connection.
Telephone Paging
The ring voltage from a phone line will trigger the AD-4x system to mute.
