OVERHEAD PRESENCE SENSOR

The DK-12 (10DK-12) Presence Sensor is an overhead-mounted active infrared sensing device that provides
detection for the triggering of automatic swing door safety functions. This sensor is designed for use with all of
BEA’s LO-21 modules, as well as the MC-15. When used with BEA’s lockout devices, the sensor is programmed to
allow two different fields of detection - one for detection when the door is in the full y closed position, and the other
for detection when the door is fully open.

As with all of BEA’s programmable sensing devices, full adjustability is achieved with the use of BEA’s hand-held
remote control unit. This allows alteration of all of the available functions as well as for inquiry of existing settings.

• Shut off all power before attempting any wiring procedures.

• Maintain a clean & safe environment when working in public areas.

• Constantly be aware of pedestrian traffic around the door area.

• Always stop pedestrian traffic through the doorway when performing tests that may result in unexpected

reactions by the door.

• Always check placement of all wiring before powering up to insure that moving door parts will not catch any
wires and cause damage to equipment.

• Ensure compliance with all applicable safety standards (i.e. ANSI A156.10) upon completion of installation.

INSTALLATION

1. Remove the left endcap by removing the two Phillips head screws. Use the Allen key provided in the

screw kit to loosen the setscrew. Finally, slide the sensor from the mounting bracket.

2. Select a mounting position for the sensor. For single door or a pair of doors, the sensor should be

centered with relation to the door opening. If the DK-12 is used on any door with an opening greater t han
6’, 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.

INSTALLATION
(CON’T)

The mounting bracket may be to a header or to the ceiling. Select the location for mounting, and secure solidly with
screws provided. To mount the unit to the ceiling, the two plastic plugs will need to be removed.

3. 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.
Do not drill holes in the aluminum-mounting bracket. (This voids warranty)

4. Slide the sensor into the mounting bracket at the desired angle. The greater the mounting angl e, the

further the pattern will be from the threshold.

: BEA recommends the use of the WHU (weather protection hood) for any DK-12 that is installed outside and

is exposed to direct weather. 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.

POWER-UP
PROCEDURES

REMOTE
CONTROL

75.0082.05 20080125

Upon completion of mechanical and electrical installation, apply 12 to 24 V AC / DC +/- 10% to the DK-12, with the
door in the closed position.

NOTE

: Refer to Programming/Set-up Section.

All adjustments to the DK-12 will be made by BEA’s infrared (IR) remote control. The IR remote control enables the
installer 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, aim the remote towards the left side of the detector (with the
end cap removed) 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.

PROGRAMMING/
SETUP

The DK-12 has been programmed with factory-default settings. They are defined on the chart on page 5 and 6.
Please review the factory default settings before making any changes to the DK-12. If at any time the factory default
settings are appropriate for your application, you DO NOT have to change them. Only change the parameters that are
needed to customize your application.

With the help of data wires from LO-21/SS-21, the DK-12 has the capability of h aving two different memory locations:
DOOR OPEN and DOOR CLOSED. This feature enables the DK-12 to have different settings for the pattern
selection and the sensitivity in both the DOOR OPEN and DOOR CLOSED positions. All the other settings of th e
DK-12 remain the same, independent of the position of the door.

DOOR OPEN & DOOR CLOSED memory location capabilities:

To program the DK-12, complete the following steps:

1. Review the default settings.

2. Determine which settings need to be changed.

3. Change any setting that is independent of the door position (relay hold time, relay mode, auto learn,

HELPFUL NOTES:

Once a set-up is launched the LED will flash at 5 Hz for approximately 10 seconds.

• If the set-up is successful, the LED will go off and the detector will function normally.

• If the set-up is not successful, the LED will continue to flash, but at a lower frequency of 2.5 Hz.

• Possible problems during setup:

a. If a person walks through the detection zone during the set-up, the set-up can be disturbed.
b. If a very reflective object is placed within 32 inches from the DK-12, it can blind the detector and make

INFORMATION

PATTERN SELECTION

The DK-12 detection zone is made up of 4 small zones placed next to each other, perpendicular to the door. The
4 zones are shown in the diagram below. There are 6 different patterns that are possible with combinations of the
4 detection zones. Please refer to the chart on the following page for the dimensions of the DK-12 detection zones
at different mounting heights and mounting angles.

The shape of the pattern can be different when the door is open and when it is closed. In the detector, there is no
link between the pattern for the open door and the pattern for the closed door. The shape of the pattern is
accessible as a function of door state and only the corresponding shape can be adjusted. The DK-12 receives
input from the LO-21 or SS-21 as to the state of the door via the data lines.

HELPFUL HINT: If the DK-12 will not enter

sensor with BEA’s remote control, and
force a door open set-up (see bottom

the red LED does not start

incorrect.

If the DK-12 has tried to launch a new set­up 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
