E ACTION
1. If the Red LED is illuminated, launch a new
set-up for the door-open position. If Red
LED goes out after Set-Up, walk-test the
pattern and tune if necessary.
2. If Red LED comes back on when door goes
open after new set-up, the DK-12 may not
be going into the door-open pattern. In the
door open position, there should be approx.
12 volts DC on the data wires at the DK-12
terminal block. Without this voltage, the
DK-12 will not go into a door open set-up.
The polarity of these wires must also be
correct. Terminal 6 is negative, terminal 7 is
positive.
3. Ensure that lockout devices are powered
and operating normally.
4. Check for proper polarity between lockout
device and operator motor.
5. If no problems are apparent with lockout
device, replace faulty DK-12.
 HELPFUL HINT: If the DK-12 will not enter
into a door-open set-up, simply unlock the
sensor with BEA’s remote control, and then
force a door open set-up (see bottom of
page7). If the red LED does not start
flashing, voltage on the data wires is
incorrect.
Door will not close or DK-
12 will not inhibit during
closing.
1. DK-12 is in detection
2. DK-12 not recognizing door open
position. Voltage or polarity of data
wires may be incorrect
3. Faulty lockout relay
4. Faulty DK-12
Red LED flashes steadily
at a rate of 2 Hz.
1. DK-12 is in detection during set-up.
1. If the DK-12 has tried to launch a new set-
up after the expiration of the Automatic
Learn Time due to a permanent change in
the field of detection, and there is continual
movement in the field, the DK-12 will flash
the Red Led indefinitely until movement has
stopped. This may also occur if there is an
object that is extremely close to the DK-12,
thereby causing saturation. Once the object
or movement has been eliminated, clear the
field of detection. The DK-12 should set-up
within 5 seconds and the Red LED should
go out. Walk-test thereafter to ensure
proper operation.
DK-12 not reacting to the
remote control
1. Batteries in the remote control are
dead.
2. Distance between sensor and
remote is too far.
1. Replace batteries in the remote control
2. Move in closer to the sensor when
programming.
 HELPFUL HINT: Use BEA’s Spotfinder to
test the output of the remote control.
Simply point the remote at the IR Spot on
the Spotfinder, press the Unlock key on the
remote, and red LED should illuminate.

Do not leave problems unresolved. If a satisfactory solution cannot be achieved after troubleshooting a problem, please call BEA,
Inc. If you must wait for the following workday to call BEA, leave the door inoperable until satisfactory repairs can be made. Never
sacrifice the safe operation of the automatic door or gate for an incomplete solution.
The following numbers can be called 24 hours a day, 7 days a week. For more information, visit www.beasensors.com.
