DK-12PRESENCESENSOR
The DK-12 is an active infrared presence sensor which is used for activation or safety on all types industrial
doors (high speed doors, sliding doors, rolling steel, vertical lift, etc.). The DK-12 projects a pyramid shaped
pattern that extends to the floor. It will automatically adjust itself upon initial programming to compensate for
bright light, shiny floors, various colors of carpeting, etc. It also has a fine tuning adjustment to accomodate
the most extreme environments.
For smaller openings, the DK-12's pattern can be reduced by shutting off one or two of the four zones
available, making it ideal for narrow doors or areas. When a door opening is 8 feet or less, one DK-12 should
be used and when a door opening is greater than 8 feet, two DK-12 s’s should be used.
Because it is microprocessor driven, the DK-12 has the ability to be programmed and to adapt to changing
environments. When the immediate area around a doorway gets cluttered with items that should not be there
such as pallets, pallet jacks, garbage cans, etc., the DK-12 will see these unwanted objects and begin to
learn the object and resume normal operation after the preset time delay expires. This is known as self-
adaptation and is adjustable from 30 seconds to 25 minutes.

INSTALLINGTHESENSOR
**B.E.A. sensors, as with all automatic door equipment, should be set up and
inspected in accordance with applicable ANSI standards.
1. Unscrew the left end cover of the DK-12 sensor, and remove the mounting bracket from the sensor by
sliding it out. To do this, loosen the allen head screw as shown below.
2. Select a mounting position for the sensor. For door opening narrower than 8 feet, the sensor should be
centered in relation to the door opening. If the DK-12 is used on any door with an opening greater than
8’, it is highly recommended to use more than one DK-12. Pattern selections will depend on the door and
the mounting position. See the chart and diagram on the following pages for pattern selection.
For openings wider than 8’ and higher than 14’
See page 7 for selecting the pulsing frequency of two
DK-12’s located next to each other
For openings narrower than 8’ and lower than 14’

*NOTE: Be sure that there are no objects within the view of the sensor lenses, such as a door roll.

3. The mounting bracket may be mounted directly to a wall or to the ceiling above the door. Select the
location for mounting and secure solidly with screws provided.

4. The installer must provide means for routing wires from the sensor to the inside of the header. The
terminal block is located at the left end of the sensor. At the back edge of the left and right end covers,
there is a small punch out slot to allow the concealed passage of wire into the sensor. A slot is also
provided at the top of the sensor, should wires need to be routed from the opposite end of the sensor.
Locate the wire passage hole on the header to keep it concealed. Once the hole is located and drilled,
pull the 6-conductor wire from the header to the sensor, and leave a few inches hanging out.
There is no need to drill holes in the aluminum mounting bracket. (voids warranty)
5. Mount the sensor back into its bracket as indicated below. The 20°position is considered standard.
6. Tighten set screw on sensor.
IMPORTANT NOTE: BEA strongly recommends the use of the WHU (weather protection hood) on any
DK-12 that is installed outside and is exposed to the elements. The circuit board of the DK-12 is not
waterproof; therefore, it is susceptible to water damage. Any DK-12 that is returned due to water
damage will be considered out of warranty.
WIRINGTHESENSOR
At the left side of the sensor, remove the 7 pin terminal connector by pulling it straight out. Connect wires as
shown below.

DETECTORADJUSTMENTS–OPERATIONOFREMOTECONTROL
All adjustments to the DK-12 will be made by BEA’s infrared (IR) remote control. The IR remote control
enables one to set-up and adjust the detector. The remote uses a modified code, which makes it
incompatible with the majority of consumer electronics. Because the end cap blocks the IR receiver after
installation, no access code is required.
To adjust the DK-12, stand to the left of the detector, pointing the remote towards the left side of the detector
(without end cap installed) at a distance less than 6 feet from the DK-12. Each adjustment requires pushing
two buttons on the remote; a “function” button and then a number. Certain buttons are not used by the DK-12
and if they are pushed, will be ignored.
When one of the “function” buttons is pressed, the indicator LED on the detector will flash rapidly. The
flashing of the LED will only occur if a function button is pushed. During the flashing, the detector is waiting
for the input of a value between 0 and 9 for its setting. If a value is not entered within 20 seconds after
pressing one of the “function” buttons, the detector will go back to the previous settings and the LED will stop
flashing. In order to continue with another try, the whole cycle must be started again. For certain functions,
not all 10 digits (0-9) are available and if an error is made, the command is ignored and the adjustment must
be redone with proper values.
The remote provides access to all the adjustments of the detector:
