Compatible with all LiftMaster, Chamberlain and Sears Craftsman digital code switch remotes listed operating on 390Mhz frequency.

The LiftMaster 423LM radio receiver is compatible with the digital code switch remotes such as LiftMaster 50LM, 53LM, 54LM, 61LM, 62LM, 63LM, 64LM, 33LM Chamberlain 50, 53, 54, 750CB, 753CB, 756CB, Sears Craftsman 139.53708, 139.53758, or 139.53778 remotes.

For open, stop close application the LiftMaster 33LM remote is highly recommend as it has color coded buttons.

The LiftMaster model 423LM is a three channel radio receiver that can operate on 18 to 30 volts ac or dc and is ideal for applications that require three receives in close proximity to each other such as three garage door openers or for commercial applications that require open, stop, close remote control. This LiftMaster 423LM radio receiver is compatible with the older 390Mhz frequency versions of remotes controls by LiftMaster, Chamberlain and Sears Craftsman listed above but we highly recommend the LiftMaster 33LM remote for use with the open, stop, close applications. Each channel of the LiftMaster 423LM receiver is independently programmable and can accept one digital code switch code with unlimited number of remotes using the same code. The LiftMaster 423LM has three independent isolated dry contacts rated at 5 amps each with channel one being able to be set for either normally open or normally closed mode by an internal slide switch. The relay output connections are made by the color coded wires extending from the receiver. Having an F-connector type antenna allows for the antenna to be remotely located from the receiver using the optional 86LM remote antenna kit (sold separately) to obtain maximum receiver range especially when if the receiver is located inside a metal enclosure that would block the signal. An optional power adaptor LiftMaster 85LM (sold separately) can be used if the receivers required operating power is not readily available. The LiftMaster 422LM receiver controls up to two door or gate openers. This item is new in box and includes 8 inch whip antenna, wire nuts and installation/programming instructions.
Note: Will not work with remotes that operate on 315Mhz. Currently there is no 315Mhz version of this receiver.
