Slide the carriage bolt into the slot on each sensor. 3. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket. 1 2 3 OPTION B WALL INSTALLATION If additional clearance is needed an extension bracket (not provided) or wood blocks can be used. Make sure each bracket has the same amount of clearance so they will align correctly. 1. Position the sensor bracket against the wall with the curved arms facing the door.

Drill 3/16 inch pilot holes for each sensor bracket and attach the sensor brackets to the wall using lag screws (not provided). 3. Slide the carriage bolt into the slot on each sensor. 4. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both sensors should point toward each other.
