DNP00006 Linear DD 24-volt, single-channel, three-terminal Delta-3 receiver, 256 selectable codes, with two single-button DT transmitters.
The web site with access to manuals is great, eliminates guess work. Easy to install and works swell.
I ordered a Linear Receiver/Transmitter set w/2 remotes and received it within five days. The products are everything I hoped they would be and work perfectly at exceptional distance from my overhead door. I would not hesitate to purchase other products through Gatehouse in the future.
