The ALARM SHUNT output on the AK-11 activates when access is granted. The "anti-passback" feature prevents using the same code twice before the programmed time elapses. The REQUEST-TO-ENTER input on the AK-11 can be wired to a pushbutton or fire access key switch to provide codeless entry for authorized personnel. If programmed for "inhibit", the input can be wired to a "service" switch or automatic timer that will disable the Relay #1 when required. If programmed for "door sense", a switch on the door detects forced entry or door ajar situations. The DOOR SENSE/INHIBIT input of the AK-11 can be used two ways. An internal sounder beeps when each key is pressed. The 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. The keypad's courtesy light illuminates the keys. The right indicator lights yellow when the keypad is in lockout condition (from too many incorrect code entries). The left indicator lights red to indicate power, then turns green when access is granted. The Linear ACP00748 AK-11 Exterior Digital Keypad features two indicators that show the status of the entry system. When power is restored to the AK-11 keypad, each relay will assume the state it was in when power was removed. The on or off toggle state of a relay is maintained even after power interruption. The relays on the AK-11 can be set for timed or latch-on/latch-off toggle operation per each individual entry code. They can activate either, or both, of the relay outputs. The Linear ACP00748 AK-11 Exterior Digital Keypad allows up to 480 entry codes, from 1 to 6 digits in length, can be programmed. The die-cast keys of the AK-11 have bright, easy-to-read yellow graphics. The keypad is housed in a rugged cast aluminum enclosure that can be mounted to a pedestal or bolted directly to a wall. The Linear ACP00748 AK-11 Exterior Digital Keypad is a digital keyless entry system designed for access control applications.
