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 appro
12 volts DC on the data wires at the DK-12
terminal block. Without this voltage, the

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
force a door open set-up (see bottom
page7). If
incorrect.
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 se
within 5 seconds a

go out. Walk-test thereafter to ensure
proper operation.
