Liftmaster 041B0692, MICROPHONE KIT
The LiftMaster 041B0692 microphone kit is a replacement microphone assembly for select CAPXL and CAPXLV high-capacity connected access systems. In these systems, the microphone is part of the visitor communication path, allowing voice audio from the entry panel to be heard by the resident, office, or call recipient. A failing microphone can make visitor audio faint, distorted, intermittent, or completely unavailable.
This part is commonly listed for CAPXL and CAPXLV access control units and may appear as 2B692 or O2-2B692 in distributor catalogs. Because the microphone connects inside the entry panel, it should be matched to the correct model generation and connector style. It should not be confused with garage door opener Secure View microphone parts or with the speaker assembly used for outgoing audio from the panel.
Common Replacement Reasons
Replace this microphone kit when visitor audio is weak, scratchy, missing, or physically damaged and the system settings, speaker/call path, and wiring have been checked. Water intrusion, corrosion, and loose connectors can cause similar symptoms.
