Unpacking and Preparation
4.1 Unpacking and Inspection
Carefully unpack the units and retain the packaging to return equipment for
servicing or repair. If the equipment is damaged in any way, return it to ENVEA or
your local ENVEA representative (for more information, see the reverse of this
manual) in its original packaging.
No responsibility for damage arising from the use of non-approved packaging
will be accepted.
NOTE
: Ensure that all items and accessories specified in the order information are present.
If not, contact ENVEA or your local ENVEA representative.
4.2 Network Layouts
For more information on layouts and connection options, refer to the relevant
control unit manual. For more information on network modules, refer to

.
Standard Systems
Connect a single sensor to the Standard Controller for a standard, single-channel
system. For more information, refer to the relevant control unit manual (see page
11
).
PRO Systems
Connect multiple sensors to the ProController either using network spurs or by
daisy-chaining. For more information, refer to the relevant control unit manual
(see page
11
).
For medium to large systems, it is best to place the control unit(s) in the centre
of the network to minimise voltage drop along cable runs. You may need to boost
power using a PSU Repeater (see section
2.3
on page
16
for details).
4.3 Prerequisites and Guidelines
4.3.1 Location Requirements
When selecting a mounting location for the sensor, the following should be
considered for optimum performance:
1. Mount in the longest, straightest, unrestricted duct available.
2. Ensure correct sensor grounding (see the section below).
3. Excess vibration will affect sensor readings. Avoid excessive vibration.
4. Ambient or radiating temperatures in the vicinity of the mounting location
must not 50 °C (122 °F).
For more information, refer to the general Installation Notes TN004 (see
