Linear Keypad with Built-in Receiver - Stand Alone

Linear's AKR-1 is a digital keyless entry system with a built-in radio receiver 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 the 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. Relay #1 has a 5 Amp capacity and Relay #2 has a 1 Amp capacity. Up to 4 sets of block coded MegaCode® transmitters (up to 480 transmitters total) can be used to gain access through 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 events from the MGT transmitter will activate Relay #2. Two indicators show the status of the entry system. The left indicator lights red to indicate power, then turns green when access is granted. The right indicator lights yellow when the keypad is in "lockout" condition (from too many incorrect code entries). The keypad's courtesy light illuminates the keys for 2 minutes after any key is pressed. An internal sounder beeps when when each key is pressed and when a transmitter is granted access. An internal jumper sets the sounder volume high or low. The DOOR SENSE/INHIBIT input can be used 2 ways. If programmed for a "door sense", a switch on the door detects forced entry or door ajar situations. If programmed for "inhibit", the input can be wired to a "service" switch or automatic timer that will disable the Relay #1 when required. The REQUEST-TO-ENTER input can be wired to a pushbutton or fire access keyswitch, to provide codeless entry for authorized personnel. The "anti-passback" feature prevents using the same code or the same transmitter again before the programmed time elapses. The ALARM SHUNT output activates when access is granted. The output can be wired to shunt alarm contacts on the access door/gate to prevent triggering of an alarm when authorized access occurs. Two solid state outputs, capable of switching 100mA to common, are programmable to signal forced entry, door ajar, lockout, alarm circuit shunting, request-to-enter, and keypad active conditions. The AKR-1 is powered from a 12-24 Volt AC or DC source. Power can be obtained from the access device or a separate power supply. The EEPROM memory retains all entry codes, transmitter information, and programming, even without power. An internal jumper is provided to reset the master code.
