WITHOUT SAFETY BEAMS:
The new LO-21K provides communication through data lines to the BODYGUARD / DK-12 to inhibit the
BODYGUARD / DK-12 in the closing cycle of the door, therefore the GREEN & BLUE wires of the LO-21K no longer
have to be connected to the BODYGUARD / DK-12. If the GREEN & BLUE wires are connected, no damage to the
unit will result.
WITH SAFETY BEAMS:
When safety beams are installed, the LO-21K provides the safety signal to the door control when the beams have
been blocked. Therefore, the GREEN & BLUE wires of the LO-21K must be wired in parallel with the BODYGUARD
/ DK-12 connection to the safety and common of the door control.
Upon powering the LO-21K , make sure that the red light on the front of the LO-21K comes on when the door is in its
closing cycle. If it does not come on, reverse the black and red wires from the LO-21K to the motor input for DC
units. If the unit is AC, ensure that the AC power is being switched on and off at the point of connection for the red
and black wires. Also, if using safety beams, ensure that the green light comes on and goes out when the beams
are blocked and unblocked respectively. Correct any faults before proceeding.
Time delay
is the only adjustment on the LO-21K. It is changed by dipswitches 1 through 5, located on the front of
the unit and can be set to achieve a 0 to 31 second delay. The time delay must be set so that the red light on the
LO-21K remains on for the entire closing cycle. As soon as the door reaches the jamb, the red light should go out.
The time delay will not begin until the motor begins rotating in a direction that allows door to close. If motor rotation
stops, the time delay will not stop counting down. Interruption of the time delay will only result if re-activation of the
door is recognized or the SBK-111 safety beams were broken. Therefore, if the closing speed of the door is
changed, the time delay on the LO-21K must also be adjusted to accommodate the time difference for the duration
of the closing cycle.

Red LED corresponds with lockout
time, and will illuminate when the
door is in a closing cycle.
Green LED illuminates upon
detection signal from the lockout
safety beams.
Set the dipswitches
according to the chart below
to achieve the desired
lockout time
(7 Second Default)
If the Bodyguard learns a “door closed” position, but does not execute a learn for the
“open door position”, place the door to a hold open position. With a BEA remote control,
unlock the Bodyguard, and with the door in the open position, press the Magic Wand key
and then the number 2 – the Bodyguard should begin flashing green to signify a set-up.
If it does not, this will be a quick indication that the improper data is being sent for the
“open door” position. Check to insure that data exists on the data lines leading into the
Bodyguard. In the full open position, voltage should be approximately 12 volts DC.
Voltage should be approximately 7.8 volts DC while the door is closing, and 0 volts DC
once closed. If it is not, check the data lines, as well as the LO-21K to Motor wires (red &
black). Refer to the Bodyguard User’s Guide for further information if necessary.
