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
®
transmitters (up to 480 transmitters
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
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.
