PRECAUTIONS
The LO-21U (PN: 10LO21U) is a micro-processed lock out module designed to operate on swing door applications with
BEA’s Bodyguard or DK-12 overhead presence sensor. The LO-21U interprets door open or door closed position based
upon motor voltage input. The motor voltage information is sent from the LO-21U to the Bodyguard or DK-12 via data lines.
The LO-21U provides optional safety beam input (dry contacts) to override the inhibit signal during closing.
