MDRM (compatible with Linear/Moore-o-Matic "Z" Series operators)

The MegaCode series of digital receivers are wireless radio controls designed for use with automatic garage door and gate openers. The MegaCode radio format provides unparalleled security. The transmitter and receiver can be programmed to more than a million different codes.

MegaCode receivers and transmitters do not contain a typical "coding switch". Each transmitter is pre-set at the factory to a unique code. The receiver is programmed by sending a signal to it from the transmitter(s) that are going to be used with it. This stores the transmitters code into the receiver's memory. The receiver will retain the memory even without power. The receiver will activate only from these "memorized" transmitters. Each MegaCode receiver can remember a maximum of 10 transmitters.

Receivers are normally powered with 24 volts AC/DC from the garage door or gate operator. Two-channel receivers provide wire connections to activate the operator's light or contro l other devices.
