Linear AK-21W Weather Resistant Digital Keypad



The Model AK-21W Weather-resistant Digital Keypad is a digital keyless entry system designed for outdoor access control applications. The keypad is housed in a rugged, plastic enclosure and is designed to be mounted in a standard 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. Relay #1 has a 5 Amp capacity. Relay #2 has a 1 Amp capacity. The relays can be set for timed or latch-on/latch-off toggle operation per each individual entry code. The on or off toggle state of a relay is maintained even after power interruption. When power is restored to the keypad, each relay will assume the state it was in when power was removed.


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.
