PRODUCT DESCRIPTION

Linear’s AKR-1 is a digital keyless entry system with a built-in radio receiver
designed for access control applications. The keypad is housed in a rugged, cast
aluminum enclosure that can be mounted to a pedestal or bolted directly to a wall.
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.

Up to four sets of block coded MegaCode
total) can be used to gain access through the AKR-1’s built-in radio receiver.
Each transmitter can be individually suspended or re-activated. Four facility codes

®

transmitters (up to 480 transmitters

can be programmed to identify each block of transmitters. A Radio Test Mode is
provided for testing transmitters and detecting radio interference. Programming of

individual (non-block coded) transmitters is not supported by the AKR-1.

Linear’s Model MGT safety edge transmitter is compatible with the AKR-1. This
supervised transmitter is used to detect and transmit obstacle events to the AKR-1
receiver. Obstacle signals from an MGT transmitter will activate Relay #2.

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 illuminates the keys for two minutes after any
key is pressed. An internal sounder beeps when each key is pressed and when a
transmitter is granted access. An internal jumper sets the sounder volume high or
low.

The DOOR SENSE/INHIBIT input can be used two ways. If programmed for
“door sense”, a switch on the door detects forced entry or door ajar situations. If
programmed for “inhibit”, the input can be wired to a “service” switch or automatic
timer that will disable the Relay #1 when required.

The REQUEST-TO-ENTER input can be wired to a pushbutton or fi re access
keyswitch to provide codeless entry for authorized personnel.

The “anti-passback” feature prevents using the same code or the same transmitter
again 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 AKR-1 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, transmitter information, and programming, even without power. An
internal jumper is provided to reset the master code.

INSTALLATION

To avoid damage to the unit from static discharges, connect the
EARTH GROUND terminal to a good earth grounding point. Suggested
wiring size is 18 AWG for earth ground and power (up to 500 feet
of 18 AWG wire can be run for power, use larger wire for longer
runs). Use 22 AWG or larger (depending on the load) for all other
connections.

✦ CAUTION: If the unit is AC powered, and one side of

the power transformer secondary is connected to earth
ground, connect the grounded side to the “-” power
terminal of the unit.

Select a location for the keypad. For door access control installations,
mount the keypad near the controlled door. For gate control
installations, mount the keypad in clear view of the gate, but far
enough from the gate so the user cannot touch the gate from the
keypad.

★ WARNING: TO AVOID SERIOUS INJURY OR DEATH,

MAKE SURE THAT THE UNIT IS FAR ENOUGH FROM
THE GATE SO THAT THE USER CANNOT TOUCH THE
GATE WHILE OPERATING THE KEYPAD. HOWEVER,
THE GATE MUST BE FULLY VISIBLE FROM THE
KEYPAD.

BASIC PROGRAMMING

When the AKR-1 is in Programming Mode, both indicators will turn
off until programming begins. After a programming option number is
entered the yellow indicator will blink. This shows that the AKR-1 is
ready to accept the new programming data. After the new data entry
is complete, the green indicator will light while the data is being
stored.The red indicator will light if any programming data is entered
incorrectly, and the command will have to be fully re-entered.

Entering Programming Mode

The 6-digit Master Programming Code (default = 123456) is used to enter
Programming Mode.

Press: # 9 # Master Code

Master Code = the current 6-digit Master Programming Code

Exiting Programming Mode

Press: * * #

The red indicator will light when Programming Mode is exited.

☞ NOTE: The AKR-1 will automatically exit Programming Mode after two minutes of inactivity.

Re-entering a Command After a Mistake

during programming, to clear the keypad and re-enter the command:

Press: * 9 #

Setting Entr y Code Length Default: 4 digits

Press: 0 3 # Length #

☞ NOTE: If the Entry Code Length is going to be changed from the factory default of four

digits, make this change fi rst, before programming any entry codes.

Length = 1 - 6 for entry code length

7

Adding a New Entry Code

Press: 0 1 # Code # Code # Relay #

Code = The new entry code: 1-999999, depending on code length

Relay = Relay output entry code will activate:

The yellow indicator will fl ash quickly while the AKR-1 searches its memory for
available space and duplicate entries. The green indicator will light when the new
code is stored.

If the new entry code chosen is already being used for another entry code, the red
indicator will light. A new unique code needs to be entered.

☞ NOTE: Leading zeros (zeros before the code number, i.e. 0001) do not need to be entered

when programming a new entry code. The AKR-1 will internally add any zeros to fi ll all
digits determined by the entry code length setting. Leading zeros will have to be entered by
the user when entering their code to gain access.

Erasing a Single Entry Code

1 = Relay #1 2 = Relay #2 3 = Both Relays

Press: 0 2 # Code # Code #

The yellow indicator will fl ash quickly while the AKR-1 searches its memory for the
code to erase. The green indicator will light when the code is erased.

Erasing All Entry Codes

★ WARNING: Performing this command will remove all

entry codes from the memory.

☞ NOTE: The green indicator will light while the memory is being erased. This may take up

to 15 seconds.

PROGRAMMING OPTIONS

There are several AKR-1 programming options. For most installations, the factory
set default options are suffi cient. The keypad must be in Programming Mode to
make these changes.

Programming AKR-1 to Hold the Output

Linear’s AccessKey products have a programmable “Toggle Mode” available for
each relay and solid-state output. When an output is programmed for Toggle Mode,
the output alternates from OFF to ON or from ON to OFF each time it is activated.

The rules for a toggle output are:

• If the output is OFF, it will turn ON and stay on until the next activation.

• If the output is ON, it will turn OFF and stay off until the next activation.

Typical Programming

With the unit in Program Mode, set the Auxiliary Relay (Relay #2) output to Toggle
Mode using the following keystrokes:

Press: 2 2 # 9 9 #

Program all normal entry codes to use the Main Relay (Relay #1), and only
Relay #1 as the output relay. Program the code(s) that you want to use to hold the
output for an indefi nite period to the Auxiliary Relay (Relay #2). See the following
example that sets entry codes 1234 for normal and 5678 for toggle operation.

Typical Toggle Mode Wiring

For devices triggered by a normally open circuit, wire the contacts of the Main
and Auxiliary Relays in parallel (see the Figure below). Either relay will be able to
trigger the access device. Entry codes programmed for the Auxiliary Relay will be
able to hold the output on.

Press: 1 0 # Input#

When programmed for DOOR SENSE, if an open condition on the input occurs
before access is granted (with an entry code, transmitter or with the request-to­enter input) a FORCED ENTRY output will occur. If an open condition remains 60
seconds after a relay activation for access, a DOOR AJAR output will occur.

When programmed for INHIBIT, a closed condition on the input will prevent
Relay #1 from activating when access is requested (with an entry code or
transmitter). This mode is typically used with an external timer to disable the
access device at certain times.

RADIO PROGRAMMING

The following programming steps are used to add, remove, suspend,
and confi gure block coded transmitters used with the AKR-1.

Programming of individual (non-block coded) transmitters is
not supported by the AKR-1.

Add Transmitter Block(s)

Sets the starting and ending TX ID numbers for up to four blocks of pre-programmed
transmitters. Enter this command up to four times
blocks one, two, three, and four. Up to 480 transmitters total, distributed in any
quantity between the blocks, can be added to the AKR-1’s memory.

Suspend/Reactivate an Individual Transmitter

This command suspends (prevents transmitter from being used), or reactivates
(un-suspends) the designated transmitter. NOTE: This command will effect the fi rst

occurrence of the TX ID in memory. If, by rare chance, duplicate TX ID numbers
occur in different transmitter blocks, contact Linear Technical Services for details
on how to suspend/reactivate individual transmitters.

Press: 9 0 # TX ID # Status #

Status = 0 for Suspend, = 1 for Reactivate

Selecting the Facility Codes Default: Ignore Facility Code

Facility Codes increase security by requiring the Facility Code as well the TX ID

MGT OBSTACLE TRANSMITTER OPERATION

One Model MGT obstacle transmitter can be programmed into the AKR-1. The
MGT is triggered with a safety edge contact and will activate the AKR-1 Relay #2
for the programmed length of time.

☞ NOTE: If an MGT transmitter is programmed, all other transmitters or entry code activations

programmed for Relay #2 will be blocked.

MGT Supervisory Mode

If an MGT supervisory condition occurs the AKR-1 will beep every 5 seconds. In
addition, all users will have to enter their entry code twice (within one minute), or
activate their transmitter twice (within ten seconds) to request access.

The MGT can monitor and produce three supervisory conditions: low battery, case
tamper/loop fault, and status. To determine the supervisory condition place the
AKR-1 in MGT supervisory mode, the same command is used to exit this mode:

Press the * , # , and “2” buttons

together for two seconds

While in MGT Supervisory Mode, the following conditions can be displayed:

Low Battery

If the transmitter detects a low battery, it will send a low battery supervisory report.
The keypad’s yellow indicator will blink.

Tamper/Loop Fault

If the transmitter case is opened or the safety edge contact becomes defective,
it will send a tamper/loop fault supervisory report. The keypad’s red indicator will
blink.

Status

Status reports are sent every hour. If no status reports are received for eight hours,
a status exception condition occurs. The keypad’s green indicator will blink.

RADIO TEST MODE

A special mode is provided to test transmitters and determine if there is radio
frequency interference present. The keypad will function normally while it is in
Radio Test Mode. To enter Radio Test Mode, use the following command:

Press the * , # , and “0” buttons

together for two seconds

The AKR-1 will beep once when the Radio Test Mode is entered. The keypad’s
yellow indicator will blink quickly when radio signals are detected. If a Linear
MegaCode transmitter is detected, the AKR-1 will beep once when the transmission
is decoded. The AKR-1 will automatically exit Radio Test Mode 45 seconds after
the last MegaCode signal is decoded.

IMPORTANT !!!

Linear radio controls provide a reliable communications link and fi ll
an important need in portable wireless signaling. However, there are
some limitations which must be observed.

• For U.S. installations only: The radios are required to comply
with FCC Rules and Regulations as Part 15 devices. As
such, they have limited transmitter power and therefore
limited range.

• A receiver cannot respond to more than one transmitted
signal at a time and may be blocked by radio signals that
occur on or near their operating frequencies, regardless of
code settings.

• Changes or modifi cations to the device may void FCC
compliance.

• Infrequently used radio links should be tested regularly to
protect against undetected interference or fault.

• A general knowledge of radio and its vagaries should be
gained prior to acting as a wholesale distributor or dealer,
and these facts should be communicated to the ultimate
users.
