B. Wiring
Each of the MSB-30's features can be used a' la carte. So depending on your application, connect only the features
that are needed.
1. If microphone audio is needed, connect the MIC AUDIO OUT (yellow wires) to the camera's Line Level Audio
In connections.
2. If arrival notification is needed, connect the PUSH BUTTON (black wires) to a trigger or alarm input, or use in
place of an existing doorbell.
3. If controlling the front panel blue LED light is needed, connect the LED CONTROL (blue wires) to a normally
open set of contacts. The blue LED will go dark when the contacts are closed. The LED CONTROL can also be
connected directly to the PUSH BUTTON (black wires) to make the blue LED wink off when the "CALL" button is
pressed.
If the camera has a motion sensing feature that is used for detecting the arrival of a person, connect the PUSH
BUTTON (black wires) to the LED CONTROL (blue wires) to give appearance the "CALL" button is functional
when pressed.
4. If additional speaker volume is needed, connect the AUX SPEAKER (white wires) to up to three 8 ohm speakers.
5. If speaker audio is needed, connect the AUDIO IN (orange wires) to the camera's Line Level Audio Output.
6. When all else is wired, connect the 12-15V AC OR DC (red/black wires) to the provided power supply adapter.
