DoorKing Part Numbers
The model 8055 is a High Security Encrypted “Rotating Code” RF Receiver that is designed ONLY for use with MicroPLUS®transmitters and is
typically installed in automatic garage door openers and vehicular gate operators. The encrypted “Rotating Code” programming in this receiver and
the companion MicroPLUS®transmitters prevent copied transmitter codes from being used again to operate the garage door or gate. The 8055
receiver can store up to 40 MicroPLUS®transmitter codes in its memory.
This receiver is NOT designed to be installed outdoors without being protected from the weather. An outdoor enclosure is available for the
8055-081 receiver if required (P/N 8057-110 - Metal Outdoor Box).
Install the 8055 receiver in a location so the antenna is NOT surrounded by metal and is in free air as high as possible above the ground.
A longer Coax Antenna kit is available for the 8055-081 receiver if required (P/N 1514-073 - Includes antenna, mounting “L” bracket and 15 feet of
coax cable).
