INTRODUCTION
Linear’s AK-21W is a digital keyless entry system designed for access control applications. The keypad is housed in a rugged, die-cast metal enclosure and is designed to be mounted in a single-gang electrical box. 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. The “anti-passback” feature prevents using the same code again before the programmed time elapses.
All system indicators and lights are long-lasting, solid-state LEDs. 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 dimly illuminates the keys at all times. The courtesy light brightly illuminates the keys for two minutes after any key is pressed. An internal sounder beeps when each key is pressed. An internal jumper sets the sounder volume high or low.
The SENSE input can be used two ways. If programmed for “door sense” the input is wired to a normally closed switch on the door to detect when the door is open or closed. Forced entry or door ajar situations can then be detected. Using door sense, the “Auto-relock” feature will prevent “tailgating” by turning off the Main Relay output immediately when the door is closed after access has been granted. If the SENSE input is programmed for “inhibit”, the input can be wired to a “service” switch or automatic timer that will disable the Main Relay when required.
The REQUEST-TO-EXIT input can be wired to a pushbutton to provide codeless activation of Main Relay, Auxiliary Relay, Output #3, or Output #4 (programmable).
The ALARM SHUNT output activates when access is granted. This output can be wired to shunt alarm contacts on the access door/gate to prevent triggering of an alarm when authorized access occurs.
The AK-21W 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 and programming, even without power. An internal jumper is provided to reset the master code. The Main Relay has a 5 Amp capacity. The Auxiliary Relay has a 1 Amp capacity. Two solid state outputs, capable of switching 100 mA to common, are programmable to signal forced entry, door ajar, lockout, alarm circuit shunting, request-to-exit, and keypad active conditions.
