We recommend that the UG-7-A6O is mounted on a distance of approximately 3 times the duct diameter before
an obstruction such as dampers, filters or bends, and approximately 5 times the diameter after these obstructions
as shown in Figure 3.

[5.2] MOUNTING OF DETECTOR ON THE DUCT
Drill a 1 ½ inch (38 mm) hole where the detector is to be mounted.
Measure the diameter of the duct.
The sampling tube should penetrate approximately 90% of the width of the duct. See Section 4 Table
4.1.
If necessary, shorten the sampling tube and insert the end plug. Figure 5.
NOTE: When installing sampling tubes longer than 2 ft. see Section 5.4
Insert the sampling tube in the Base Part. Figure 6.
Secure the sampling tube by fastening the screw. Figure 7.
Insert the sampling tube in the duct and secure the UG-7-A6O to the duct using the three provided
