External Monitoring
LZR-microscan T hub/sensors are intended to be monitored by the door system for proper operation (see Tech Bulletin
#53).
If the door control does not utilize monitoring, do not use monitoring wires.
If utilizing the monitoring function, the sensor LED will briefly flash RED during monitoring communication with door
control. This indicates that external monitoring is functional. Monitoring functionality must be active on the sensor
and monitoring wires must be properly connected to the door control.

IMPORTANT:
• All wiring harnesses used must a) be routed separate from any mains or non-class 2 voltage cables,
or b) be rated for the mains voltage and suitable protection.
• Routing means must be used in accordance with national and local codes.
Most doors require the use of the LZR-microscan T Power Supply.
For information on powering directly from door control see Tech Bulletin #53.
NOTES
:
1. LZR-microscan T hub/sensors must be powered by a UL Class 2 power
supply limited to 15 W.
2. If a NEMA 5-15R outlet is not available in door header, cut off
NEMA 5-15P plug and wire-nut to 110 VAC observing polarity and
grounding.
NOTES
:
1. If using two door controls. When one door control is used for pairs, refer to instructions for "single" (above).
