|Linear AK-31 Interior Digital Keypad
The Model AK-31 Low-cost Interior Digital Keypad is a digital keyless entry system designed for 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.
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). 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.
The AK-31 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.
