Pole mounting

Figure 3-7 Pole Mounting Diagram

In large open areas it is recommended that the GDU-Incus is pole mounted to take advantage of the

large omni-directional detection coverage. The detector should be mounted 10 to 16 ft. (3 to 5 m) high

to eliminate reflections and ground absorption. The GDU-Incus may be used lower than 10 ft. (3 m) but

coverage may be reduced, please contact an Emerson representative for details.

The pole should be mounted to local standards and be capable of supporting the detector weight at the

installation height when environmental factors are taken into consideration.

The GDU-Incus is attached to the pole using 2 U-bolts fixed to the pole mounting adapter (wall bracket

can be used for pole mounting if the pole is 1.5-in. to 2-in. [38.1 mm to 50.8 mm] diameter).

Suggested U-bolt torque is 45 Nm but local standards should be used in the first instance.
