Linear Delta-3 Radio Receiver Model DR (part number DNR00001)
Linear model DR radio receiver has been used (and is still being used)
as an external radio receiver on many brands of garage door operators.
From the 1970's into the 1990's there were many different brands of
garage door openers that would use external radio receivers (instead of
today's openers that have the radio receivers built into them). One of
the top receivers that was used in the Linear Delta-3 single channel
digital radio receiver found here.
You may find these receivers on
older Genie, Stanley, Raynor, Overhead, Chamberlain, Liftmaster,
Allister or other makes. Most operators will have a 24v power hookup
directly on the operator so the radio receiver can be powered but if it
doesn't then you'd need to use a transformer to power the receiver.
the back of the radio receiver you can see a recessed area with 8 DIP
switches inside. These 8 DIP switches can be set to either ON or OFF
position. You decide how you want to set them (we recommend not setting
them to all ON or all OFF). Then to get your Linear DT-1 Remote
to work you'll match the 8 DIP switches in the remote to the same
position that you set the switches in the radio receiver. Very simple
programming and you can add as many remotes as you want as long as they
are all set to match the radio receiver.
DR Linear Delta-3 radio receiver was used on many of the older Raynor
garage door openers such as the R170/270, R160/260, R150/250, and R130.
