COMMISSIONING
Commissioning the Detectors
The commissioning of the detectors requires the
detectors to be positioned so that they cover the
required detection area, and may require their range
to be adjusted.
Positioning the detectors
(1) To position the detectors, move the detector
head until the required area is covered (UD
options move in one direction, UDA options
move in two directions).
Adjusting the range
This is not normally necessary as the detector is
factory set to suit most requirements, however
sometimes it may be necessary to reduce/increase
the detection pattern of the detector. To do this:
(1) Turn the lower adjustment screw until the
range is as required (clockwise reduces
the range).
Setting Up the IQ Controller
If an IQ Controller is being used to process inputs
from the OCC/U system, or to output a signal to it,
its strategy must be configured to do this. If a digital
input is used the necessary strategy should follow
the rules for fast sequencing.
Information on how to configure an IQ controller can
be found in the IQ Controller Configuration Reference
Manual (90-1533).
It is also important that the input and output channels
are configured to be of the correct type; this is
described in the appropriate controller’s data sheet.
