We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.

Q
Do I need the dsr1 and this to control the door chime of this does it on its own?

A
The harness will not work by itself and requires the DSR1 to work
jason  Aug 30, 2020 (Staff)
Q
So this alone will control the door chimes or does it have to be paired with the dsr1?
alex  Aug 12, 2020
1 answer
A
This is only the T-harness, and needs the DSR1 to work and to keep the door chimes.
