2. 4. Mounting for Duct Installation
The following instructions are applicable for both the Source unit and the Detector
unit.
The detector may be mounted on special Duct Mount. The Duct Mount enables the
detector to be rotated up to
±
3 degrees in the X-Y directions in order to provide fine
alignment.
For duct installation use Duct Mount P/N 794716.

Duct Mount Set (Figure 2-4)
The Duct Mount set consists of Fitting Plates, Sealing Rings, Windowed plate, and
securing elements combined with appropriate screws and nuts. It provides a reliable
attachment of the detector to the air intake as well as good sealing and accurate
alignment capability
2. 4. 2.
Alignment Set (Figure 2-5) and Accessories
Air Duct Installation has a limitation which is the disability of viewing at the
Detector’s front and performing fine alignment through detector aim such as
performed in standard installation. As a result, fine alignment of the Detector’s Mount
should be provided
before
the detector assembly mounting
.
The Alignment Set solves this problem by enabling the installer to align the Detector
Mount first, and then to install the Detector. The Alignment Set includes a Mount
that is identical to the Detector Mount Surface and a telescope that is installed in the
middle of the Mount Surface. The Telescope is centered in the Duct mount in a way
that it is located in the same optical axis as the detector that should be mounted later
in the same location.
The Accessories supplied with the kit includes one No.10 Key for installation and for
alignment. One Accessories Set is supplied for each installation.
