1. Check terminals 1 & 2 for proper voltage
24 V AC/DC + 10%.
Make certain that the field of detection is all
clear during the set-up and that all lenses
are installed on the DK-12. If detection of
movement is encountered upon initial set-
up, the DK-12 will continuously flash red at

+ 2 Hz. The DK-12 will also not set-up if
permanent stationary objects are extremel
close to the sensor. Ensure that, not only
is the detection field all clear, but that the
sensor is mounted properly (using the D
12 mounting block if necessary). If the
mounting block is not used, and the
backside of the sensor is less than 3” to the
face of the door, it may be in saturation due

Remove and re-apply power to the DK-12.
Allow set-ups to complete for door open and

Check to ensure that there is no detection
occurring at the DK-12. If the Red LED is

Remove the output wires (common,
normally open, normally closed) from the
DK-12.
CAUTION – there may possibly be
no safety on the door when this test is
performed.
Activate the door control, if the
door opens, the fault exists with DK-12 or
related wiring. If door does not open, the
faults may exist with the door control or it’s
related wiring.
Disconnect the green & blue wires from t
LO-21 to the door control safety and
common terminals. If door opens when
triggered, fault lies within the lockout safety
beam set, or possibly with the LO-21. Refer
to the LO-21 troubleshooting procedures in
the respective manual.
Check to insure proper relay output setting.
Refer to page 6. Typically, relay setting
should be ‘Normally Open’. This means the
