I. INSTALLATION
NOTES
* SURVEY THE DOOR:
- Verify that the door control and operator is functional and operational before beginning.
- Check BOTH sides of the door for the following: distance from pivot edge, distance from the top of the door, frame clearance, finger guard, door arm, etc. Check that the location is clear and free of any obsutrctions.
* SENSOR LOCATION IS IMPORTANT: It is best practice to mount the sensors as close to the top of the door.
Mounting height from finished floor to the sensor LED must be within the range of 75" to 98".
* USE A SPACER, IF NECESSARY: Be sure to use a spacer when door hardware extends across the width of the door and is more than 2 inches thick.
* USE A MOUNTING ARM, IF NECESSARY: Be sure to use the Mounting Arm kit when mounting on a narrowstyle aluminum door.
Refer to Mounting Template 75.5908 when using the Mounting Arm kit.
* HOLE SIZE: Be sure to comply with hole sizes called out on the Mounting Template.
*
LZR-MICROSCAN T SENSORS AND MOUNTING ARM ACCESSORIES ARE HANDED. PLEASE OBSERVE
WHEN MOUNTING.
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.
A) INSTALL MOUNTING ACCESSORIES (IF REQUIRED)
• If a mounting arm is needed for this application, align the Mounting Template (75.5908) in the desired location, and mark and drill the required holes.
» If a spacer is also required for this application, secure the spacer to the mounting arm, and then secure the sensor to the spacer.
»
If no spacer is required for this application, simply secure the sensor directly to the mounting arm.
• If a spacer only is required for this application, mark and drill the SPACER MOUNTING HOLES on
Mounting Template (75.5754), and then simply secure the sensor directly to the spacer using the
