LO-21K
LOCKOUT RELAY
The LO-21K (PN: 10LO21K) is a micro-processed lock out module designed to operate with the Keane Monroe
3100 Swing Door System ONLY! The LO-21K is used with BEA’s Bodyguard or DK-12 overhead presence sensor. The LO-21K interprets door open or door closed position based upon motor voltage input. The motor voltage information is sent from the LO-21K to the Bodyguard or DK-12 via data lines. The LO-21K provides optional safety beam input to override the inhibit signal during closing. For example, when the safety beam path is blocked or interrupted during closing, the inhibit data will be cancelled, thus initiating a safety signal to the door control safety input.
ANSI / BHMA 156.10-2005 requires the use of a sensor or photobeam on the swing side of the door when using a header mounted safety sensor, such as the Bodyguard or DK12. For more information reference the ANSI 156.10 standard.
The LO-21K module is designed specifically for the KM3100 K-Control only, and must not be used on other brands/models of operators! Damage to module may result if this occurs.

PRECAUTIONS
!
CAUTION
•
Shut off all power going to the header 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.

ELECTRICAL
INSTALLATION
OPERATION
The LO-21K can be used with the BEA SBK-111 safety beams, in addition to dry contact safety beams, for retrofit purposes. Since the SBK-111's are wet output and all other safety beams have a dry output, there are some wiring differences between the two. The SBK-111 is wired as shown in the wiring diagram.
If using dry contact safety beams, such as BEA’s Microcell, remember these changes:
1. Power the safety beams with the same transformer that is used for the LO-21K.
2. The black/ white striped wire is not used and should be taped off.
3. The gray and purple wires of the LO-21K go to the NO and COM dry contacts of the safety beams.
All LO-21K wiring must be accomplished with the module unplugged. If the red / white striped and white wires (data wires) touch each other when power is applied, damage to the unit will result. white green brown brown white

MOTOR
The function of the LO-21K with the BODYGUARD / DK-12 is as follows. The LO-21K provides the BODYGUARD /
DK-12 with information on the position of the door by data lines. These data lines (RED/WHITE & WHITE) enable the BODYGUARD / DK-12 to be inhibited during the closing cycle of the door and to switch its pattern settings according to the position of the door. For example, when the door is in its fully open position, a signal will be sent through the RED/WHITE and WHITE to the BODYGUARD / DK-12 to indicate that the door is in this position, and the BODYGUARD / DK-12 will switch to a “door open” pattern. Once the door starts to close, the LO-21K will sense the reversing (change of polarity) of the motor and will inhibit the BODYGUARD / DK-12 for the preset lock out time delay. During this time, the red LED at the sensor will be off.
In addition to providing communication to the BODYGUARD / DK-12, the LO-21K provides a safety connection between the safety beams and the door control. The BLACK/WHITE & RED/WHITE wires provide the SBK-111 safety beams with the necessary voltage to operate. If the safety beams are blocked, the GRAY & PURPLE wires will receive a signal for the LO-21K to trigger the safety of the door control via the BLUE & GREEN wires of the LO-
21K. The safety signal received by the door control will hold the door in its position. If the safety beams are broken during the closing cycle, the BODYGUARD / DK-12’s pattern will be adjusted to its “door closed” pattern and the safety of the door will be triggered. When the safety beam path is reestablished, the door will continue to close in safety swing until the door reaches the fully closed position, at which time activation will be possible only if there is no detection at the Bodyguard.

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.
STOP
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.
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.
