The Apex system components can be used together in a variety of ways for different installation
requirements in a hazardous environment. For installations of certified components also refer to the
Control Drawings in Appendix B.
The following types of system installation are typical examples of those that can be made:
•
Apex Transmitter unit with a Certified Sensor locally mounted at the Transmitter
Unit and field wiring from the Transmitter Unit to the system controller.
•
Transmitter unit with a Certified Sensor mounted remotely in a Certified
Junction Box, with field wiring between the two components, and from
the Transmitter Unit to the system controller.
This chapter describes how to:
•
carry out the installation of a Transmitter Unit and Certified Sensor
•
install an Certified Junction Box accessory with Certified Sensor, suitable for
remote operation
•
install a LonWorks Communications Board in a Transmitter Unit
This is to enable the unit to be controlled and communicate over a digital network,
e.g. LonWorks.
Caution: Do not install a communications board into a UL or CSA certified Transmitter Unit
•
install the system accessories
When fitting the system components consideration should be made regarding potential gas leak
sources, density of the gas to be detected, probability of mechanical impacts and interference from
other equipment and apparatus.
For optimum performance the Transmitter Unit and Certified Sensor should be installed in a location
free from dust and direct sunlight. Sunshade and weather protection accessories for the sensor are
available when operating in harsh external environments (see 3.4).
Refer to the relevant control system manual for external network connection information (e.g. field
.
wiring, etc.)
