Linear Exterior Digital Keypad with MegaCode Radio Receiver | LIN-AKR-1
The Model AKR-1 Exterior Digital Keypad with Radio Receiver is a digital keyless entry system designed for access control applications. The keypad is housed in a rugged cast aluminum enclosure that can be mounted to a pedestal or bolted directly to a wall. The die-cast keys have bright, easy-to-read yellow graphics.
Up to 480 entry codes, from 1 to 6 digits in length, can be programmed. They can activate either, or both, of the relay outputs.
Up to four sets of block-coded MegaCode® transmitters (up to 480 transmitters total) can be used to gain access through the AKR-1's built-in radio receiver. Each transmitter can be individually suspended or re-activated. Four facility codes can be programmed to identify each block of transmitters. A Radio Test Mode is provided for testing transmitters and detecting radio interference. Programming of individual (non-block coded) transmitters is not supported by the AKR-1.
Linear's Model MGT safety edge transmitter is compatible with the AKR-1. This supervised transmitter is used to detect and transmit obstacle events to the AKR-1 receiver. Obstacle signals from an MGT transmitter will activate Relay #2.
