4.3 DU Outdoor Mounting
The mounting bracket has 4 mounting holes for 1/4-in lag bolts. Three are in a triangular
pattern, the fourth is a circular slot. Only the circular slot and one other hole is shown in
the previously given figures.
4.3.1 Mounting to a wood structure
1. Use the holes in mounting bracket as a template and mark the hole locations. Mark
two regular holes if no motion is required or one hole and the circular slot if motion is
required for optimizing the orientation of the DU.
2. Drill two 1/8-in. diameter holes approximately 2.5-in. deep.
3. Install the DU using the two 1/4-in. lag bolts.
4. If additional security is required a third hole and lag bolt could be used after correct
orientation is determined.
4.3.2 Mounting to a brick or concrete structure:
1.
Use holes in mounting bracket as a template and mark the hole locations. Mark the
two regular holes if no motion is required or the hole and slot if motion is required.
2. Use a masonry drill bit to drill two 5/16-in. diameter holes, 2-in. deep.
3. Insert masonry screw anchors so that the anchor is flush to the mounting surface.
4. Install the DU using the two 1/4" lag bolts.
5. If additional security is required a third hole and lag bolt could be used after correct
orientation is determined.
4.3.3 Mounting to a pipe:
Use the supplied two stainless steel hose clamps.
1.
Feed the end of the hose clamp through the rectangular slots as shown in Figure
4.4: "Pipe Mount".
2. Aim the DU at the signal source and tighten clamps.
Note: DO NOT use cable ties to mount the DU.
4.3.4 Attaching the cable
Figure 4.5: Drip Loop
While securing the cable, ensure that a drip
loop is fashioned near the DU (to prevent
water from collecting around the cable where it
attaches to the DU).
Fashion the drip loop and fasten a black tie
wrap around the loop to keep the loop
secured as shown in Figure 4.5: "Drip Loop".
