Linear Access Control Digital Keypad, Outdoor is deisnged for outdoor applications.
The 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.
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 can be programmed to activate indefinitely, or for 1, 2, 3, or 4 minutes after the last key press, or not light at all. An internal sounder beeps when each key is pressed. An internal jumper sets the sounder volume high or low.
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.
