There should only be one analogue detector loop per shielded cable.
Analogue detector loops and conventional sounders should not run in the same shielded cable.
If the system requires one or more repeaters, it will be necessary to use a four core data cable to create a
data loop between the panel and the repeater. Alternatively, it is possible to use multi-mode dual-core
fibre-optic cable or a TCP/IP connection for the same purpose.
Data loop cable should be RS422/485 grade data cable, eg:

Limitations
A fire alarm system can provide early warning of a developing fire but it does not assure protection
against damage or loss resulting from a fire.
The fire alarm system should be designed and installed in accordance with all relevant regulations
and codes of practice.
To ensure maximum protection the system should be regularly tested and inspected by qualified fire
alarm installation personnel. Inspection and testing should be carried out in accordance with the
appropriate local standards.

OVERVIEW
Definitions
Analogue Loop The physical link, usually fireproof 2 conductor shielded wiring cable, forming a ring of
interconnection between sensors and the detection panel.
Cable form A connecting lead. Typically a length of flat cable with connectors at both ends.
Conventional Sounder A Conventional Sounder is an audible output device that is connected to the
Conventional Sounder outputs on the Panel. It is different electrically to a Loop powered Sounder.
Data Loop This may take the form of RS485, a fibre optic link or by TCP/IP. It provides communications
between the Panel and Repeaters.
Detector Any type of fire sensor (heat, smoke) that is connected to an Analogue Loop.
Device A detector, sounder, interface module or call-point connected to an Analogue Loop.
Evacuate A system state where all sounders are activated simultaneously. Pressing SOUND ALARMS
will generate an evacuate condition.
Fibre Optic Link A connection method for data that uses light instead of electrical signals. The
connection is made using fibre optic cables rather than copper electrical cables. Fibre optic signals can
travel far greater distances than electrical signals with less risk of electromagnetic interference.
Flash Non-volatile memory inside the panel used to store the program and the customer site data. Flash
data storage is very robust and needs no power at all to retain the data.
Local Sounder A local conventional sounder is an audible output device (bell or sounder) that is
connected to the local bell output on the panel.
Loop Sounder The term Loop Sounder is used to describe an audible output device that is connected to
and controlled individually by an Analogue Loop. Loop Sounders are different electrically from
Conventional Sounders.
NVRAM Non-volatile Random Access Memory. Any information stored in this memory will not be
cleared when power is removed from the system. The system has an internal battery for the NVRAM.
PCB Printed Circuit Board.
Repeater A Repeater is a remote terminal to the Panel. Everything that is displayed on the Panel, with the
exception of zonal LEDs, is also displayed on the Repeater. Any LEDs illuminated on the Panel are
illuminated on the Repeater. Key presses at the Repeater are sent directly to the Panel, as if the input were
actually occurring at the Panel.
SIM CARD Single In-line Memory Card. Fitted to the SIM CARD is the Flash memory that contains the
Panel software and the system settings (Customer Flash Memory ).
The System The Panel, Repeaters and all devices.
Zone A situational group of devices. A Zone can consist of a collection of any of the devices connected
to the system.

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.
