INTRODUCTION
Linear’s AK-21Wis a digital keyless entry system designed for access control
applications.The keypadis housedin a rugged, die-cast metal enclosure andis
designedto be mountedin a single-gangelectrical box.The die-cast keys have
bright,easy-to-readyellowgraphics.
Up to 480 entry codes, from1 to 6 digits in length, can be programmed.They can
activate either, or both, of the relay outputs.The“anti-passback” feature prevents
usingthesamecodeagainbeforetheprogrammedtimeelapses.
All systemindicators and lights are long-lasting, solid-state LEDs.Two indicators
showthe status of the entry system.The left indicator lights red to indicate power,
then turns greenwhenaccessis granted.The right indicator lights yellowwhen
the keypad is in “lockout” condition (fromtoo manyincorrect code entries). The
keypad’scourtesylight dimlyilluminatesthe keysat all times.Thecourtesylight
brightlyilluminatesthekeysfor twominutesafter anykeyis pressed.Aninternal
sounder beeps when each key is pressed. An internal jumper sets the sounder
volumehighorlow.
The SENSE input can be used two ways. If programmed for “door sense” the
input is wiredto a normallyclosed switchon the door to detect whenthe door is
openor closed.Forcedentryor door ajar situationscanthenbe detected.Using
door sense, the “Auto-relock” feature will prevent “tailgating” by turning off the
Main Relay output immediately when the door is closed after access has been
granted. If the SENSE input is programmed for “inhibit”, the input can be wired
to a “service” switch or automatic timer that will disable the Main Relay when
required.
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).
The ALARMSHUNT output activates when access is granted.This output can
be wired to shunt alarmcontacts on the access door/gate to prevent triggering of
an alarm when authorized access occurs.
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. An
internal jumper is provided toreset the master code.The Main Relay has a5 Amp
capacity. The Auxiliary Relay has a 1 Amp capacity. Two solid state outputs,
capable of switching 100 mA to common, are programmable to signal forced
entry,doorajar,lockout,alarmcircuitshunting,request-to-exit,andkeypadactive
conditions.
