5.5.5 Duct Mount Alignment (Figures 11,12)
The following instructions are applicable for both the Light Source unit and the
Detector unit.
1. Connect the Telescope Plate (Figure 12, item 1) to the Duct Mount
Alignment Plate (Figure 11, item 8).
Insert each one of four Screws (Figure 11, item 15) from the Duct Mount
side through the Hole (Figure 12, item 2), and secure it with Nut and Flat
Washer (Figure 11, item 15).
2. Locate the Telescope Aim (Figure 12, item 3) to be in vertical to the
Installation surface.
3. Look at the Aim view and locate the ‘Aim Cross’ in the middle of
Installation Surface Hole on the opposite side. Rotate the Vertical and
Horizontal Nuts (Figure 11, items 10,14) to achieve best result.
Provide stability of the plate by securing and releasing the opposite nuts or
screws gently.
4. Repeat step 3 until best result is achieved.
5. Provide final Screws and Nuts securing (Figure 11, items 9,11).
6. Remove the Alignment set carefully by unscrewing The Nuts and Screws
from the Hole (Figure 12, item 2).
7. Perform detector wiring according to section 5.6 Note that in case of Air
Duct installation the Detector is mounted at the front side. Therefore, it
must be removed from its mounting before any cover opening.
8. Install the Detector/ Light Source on the Alignment Plate (Figure 11, item
8).
9. Secure the Detector/ Light Source with Nuts and Flat Washers (Figure 11,
item 15).
