Customer Q&A

2 questions already asked

Q
Do I need the dsr1 and this to control the door chime of this does it on its own?
[ Alex  Aug 17, 2020 ]
1 answer
A
The harness will not work by itself and requires the DSR1 to work
[ Paul  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.
