Combined loudspeaker and microphone
This representation identifies an electroacoustic device serving loudspeaker and microphone roles.
Plan symbol for an intercom door station with speaker and microphone, used for visitor entry.
In plain English
Door intercom stations combine a loudspeaker, microphone and call button, and sometimes a camera, at a building entry. Plans draw a box with combined loudspeaker and microphone marks, tagged IC or DS, beside the door.
The station links to indoor answering units and often to an electric door release. The plan should show this link so the installer runs the right cabling. The symbol does not show whether the system is two-wire, IP or audio-only.
Find the linked answering units. Check for door release interface. A combined loudspeaker and microphone symbol is a component; this marks a complete entry station.
