12.1.5 Extension unit EXU-SA
This extension unit has inputs for door mounted sensors, which can give presence impulse on approach side
and/or presence detection on swing path side. Relay output for error indication or door indication is also integ-
rated. When the jumper for the relay is set to ‘Open door indication’, its activation will follow the Blanking LED.
