4.4.3 Alignment of Ventilation Zone (VZ) Cross Duct Units
Where it is necessary or desirable for Cross Duct ELDS systems to be installed across the front of
the entrance to a duct, Ventilation Zone (VZ) Cross Duct ELDS systems should be used. ELDS VZ
units are effectively Cross Duct ELDS units supplied with the standard Adjustable Mounting
Brackets instead of Mounting Plates. The mounting brackets enable ELDS VZ units to be mounted
across the front of the duct entrance and provide for any adjustment that might be required to
achieve acceptable alignment in such a location.
Alignment of ELDS VZ units should be performed using the standard, Senscient-supplied
Alignment Telescope and the alignment procedure described in section 4.3. Due to the wide field-
of-view (≥ 6°) of Cross Duct ELDS units, users will find that small changes in alignment will have
no effect upon the signal levels or performance of ELDS VZ units. Consequently, there is no need
for fine-tuning of the alignment of ELDS VZ units - a quick centering of the telescope cross-hairs
on each end of the system will always be sufficient.

4.5. Commissioning Using SITE
The necessary steps to commission a system are outlined in the following sections.
4.5.1 Commissioning a Transmitter
Calibration data is held within each Transmitter unit and is copied to the Receiver as part of the
installation and commissioning process. For this reason it is necessary to
commission the
Transmitter unit first , before attempting to commission the Receiver of an ELDS system.
