The AKR-1 is a digital keypad entry system that includes a built-in radio receiver. It allows use of up to 480 block coded transmitters, in addition to 480 traditional keypad entry codes. Users can be assigned either type of code for system access.

Two relay outputs are provided: one for gate or door access; the other for gate obstacle control using the MGT, the industry's only supervised safety edge transmitter. If an MGT is not used, the second relay can control another door or gate.

Installation and set-up are simple. The AKR-1 operates on 12-24 volts, ac or dc. It can be powered directly from the radio power output of most gate operators. Learning, suspending, or deleting entry codes or transmitters is as easy as pressing a few keys on the AKR-1's built-in keypad. Program data is stored in non-volatile EEPROM; data retention is in excess of 10 years, even in the event of a power failure.

The AKR-1 is compatible with all of Linear's block coded transmitters, which are programmed and supplied in sequential order. Each transmitter is labeled with its unique ID code and also has a facility code. The combination of these two codes provides the same level of security as a traditional Wiegand swipe or proximity card.
