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 ALARM SHUNT output 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 can be wired to a pushbutton or fire access keyswitch 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 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. Two indicators show the status of the entry system. When power is restored to the 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 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. Up to 480 entry codes, from 1 to 6 digits in length, can be programmed. The die-cast keys 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 Model AK-11 Exterior Digital Keypad is a digital keyless entry system designed for access control applications.
