INSTALLATION & COMMISSIONING MANUAL - REVISION 1.0 - 19.FEB.2007
INSTALLATION
Introduction
This section covers the physical installation of the system. It primarily focuses on the parts that are required
and how they should be connected together. Do not connect the mains power or the batteries at this stage;
commissioning the system is covered in the next section of this manual.
Installation should always be performed in accordance with a system plan.
Panel
The control panel should be located where access to the internal components is not restricted and where
the unit is not exposed to high levels of temperature, moisture, vibration and shock.
Any metal swarf could damage the PCBs if it is still present when the panel is powered up so it is
recommended that all PCBs are removed from the box whilst the box is being installed. Make a note of the
positions of the PCBs before removal.
Mains Power Connection
The panel must be earthed. The LIVE connection must be made to the fused input on the power supply
module. This input will also have a BLACK or BROWN wire leading into the power supply unit.
The connector with a BLUE wire leading into the power supply unit is the NEUTRAL.
Other Panel connections
These are detailed in the relevant following sections. Most connections are made from the JUNiOr
mainboard.
Repeaters
Repeaters Zare installed in a similar manner to the Panel. Each Jr. panel can supply a maximum of 4
Mini-repeaters.
The Repeater should be located where access to the internal components is not restricted and where the
unit is not exposed to high levels of moisture, vibration and shock.
Avoid placing the Repeater in direct sunlight as this may impair reading of the LCD display.
Any metal swarf could damage the PCBs if it is still present when the Repeater is powered up so it is
recommended that all PCBs are removed from the box whilst the box is being installed. Make a note of the
positions of the PCBs before removal.
