The Linear DD Delta-3 Double Garage Opener with Receiver and 2 Transmitters is a single-channel wireless radio control designed to use with automatic garage/gate operators and access control systems. All Delta-3 products (on the same frequency) can be mixed and matched to suit your individual needs. The Delta-3 radio format provides 256 different digital codes. The codes are set using the 8-position coding switches in the units. If you only need one transmitter, you can get the DS Delta-3 Single instead.
