LO21, Lockout Relay

Product Line: Lockout

BEA’s LO21 is a micro-processed lockout module designed to operate on swing door applications with either BEA’s Bodyguard or DK12 overhead presence sensor. The LO21 interprets door open or door closed positions based upon motor voltage input. The motor voltage information is sent from the LO21 to the Bodyguard or DK12 via data lines.

The LO21 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.

LO21 Versions:


  • Used to lock out header-mounted safety sensors while the door is in closing cycle.
  • Recognizes the position of the door by reading the motor voltage.
  • Communicates the position of the door to the door-mounted safety sensor
