 Stand Alone Exterior Digital Keypad Entry
SystemThe New
Model AK-21W Weather-resistant Digital Keypad is a digital keyless entry system designed
for outdoor access control applications. This unit replaces the Model AK-2W with added
programming features. The die-cast keys have bright, easy-to-read yellow graphics. 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 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) for authorized
personnel. The “anti-passback” feature prevents using the same code twice before
the programmed time elapses. 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. 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-enter, and keypad active conditions.
