How to Restore an Alarm
Alarms, faults and tampers will be restored provided:
1. The cause has cleared
2. An authorised user PIN code or anti-code has been entered.
3. The conditions have been viewed on the keypad display after steps 1 and 2 above.
If a user cannot restore all the conditions, a temporary banner is displayed to indicate that a manager or
engineer is required to restore the system. This lasts for 30 seconds before the normal banner is displayed.

SECTION 4:  SYSTEM WIRING
General Information
It is essential that this product is installed correctly, in particular with respect to a person’s safety and connec-
tion to the mains electricity supply. This product is not suitable for installation, maintenance or connection by
the user. A competent, qualified engineer, with for example NACOSS approval, must carry out installation and
maintenance.
Siting
The control panel enclosure (plastic box or metal box), must be sited indoors in a secure area where it cannot
be readily interfered with. There must be adequate ventilation, ample light and easy access for servicing and
maintenance. It is not suitable for siting externally or in harsh environments where it could be subject to high
humidity, extremes of temperature, chemical atmospheres, high dust levels, or in a position where it may be
subject to being dripped on, or splashed by, water or other fluids.
The enclosure base must be securely fixed to a vertical, smooth, solid surface that is a part of the fabric of the
building. The position chosen must allow the cabinet lid to be removed and allow unhindered access for
installation and maintenance.
Ventilation
While the control panel has been designed so that no part attains an unsafe temperature it is important that
adequate ventilation is provided around the cabinet, therefore the cabinet must not be positioned close to
heat-radiating equipment or other sources of heat.
Cabling
The panel has high voltage barriers between the a.c. mains supply and the alarm wiring terminals. It is essential
that these barriers be maintained in the way the cables enter the cabinet, are routed inside the cabinet, and are
routed externally.
Additional holes must not be cut in the enclosure, rear entry points are provided for cables. Alarm system
cables must be neatly trimmed and not allowed to loop inside the cabinet.
Cables external to the cabinet must be either firmly affixed to the fabric of the building using suitable clips or
saddles, or mechanically protected in conduit or trunking. It must not be possible to put strain on the wiring
within the control cabinet by pulling on cabling external to the cabinet.
It must not be possible to push a finger or similar size object or instrument into any hole or cable entry point.
Mains Cable Type
The conductors of the mains supply cable must have a minimum cross-sectional area of 0.75 mm and the
insulating material on each conductor must be a minimum of 0.4 mm thick Polyvinyl Chloride (pvc). Flexible
cables must conform to the requirements of BS6500 and IEC Publication 227. Non-flexible electrical installa-
tion cables must conform to BS6004.

Galaxy 2 Series Installation Manual
NOTE: Connections shown as dashed lines
are factory made. The metal box
must be earthed.
Figure 2. Mains Connection to the Galaxy 2 Series
The outer covering insulation must be clamped under the cable clamp. It is important that this cable enters the
control panel enclosure through the mains entry hole next to the mains terminal block, is not looped within the
control panel enclosure and does not run close to other system cables inside or external to the enclosure.
WARNING:The control panel enclosure must not be opened before isolating the mains supply.
Illumination of the green power LED 2 indicates the presence of a.c. mains supply. The
cover of the Galaxy 2 Series enclosure must be replaced whenever any connection to the
BT master socket is completed to prevent exposure to potentially lethal voltages from the
PSTN.
System Wiring (cont’d)
Zone and Data Cable Type
Zone cables and all cables between the panel, keypads and expansion modules must be as follows:
RS485 Bus:  Twisted pair screen cable Belden 8723 equivalent. For systems with less than 100m cable run
in total, standard 4-core alarm cable may be used in most normal environments.
ECP Bus and Zone Cables:  Standard 4-core alarm cable.
Zones: Standard 4-core alarm cable.
Mains Supply Connection
The connection to the a.c. mains supply must be made by a competent, qualified person, for example NICEIC
approved, in accordance with the current IEE and local supply regulations.
Warning: A means of isolation from the mains supply must be provided within two metres of the
control panel. Where live and neutral supplies can be identified, a fused spur with a 3A
fuse, must be fitted on the live circuit. Where live and neutral circuits cannot be reliably
identified, 3A fuses must be fitted to both circuits.
Where a flexible cable is connected to the control having cores coloured brown and blue it is important to
connect the wires to the mains terminal block as follows:
• Blue (Neutral)  – connect to terminal N
• Green/Yellow (Earth) – connect to terminal E
• Brown (Live)  – connect to terminal L
From a.c. mains input

Equipment Electrical Rating
The control equipment is designed to operate on a mains supply of 230 Volts a.c. (230 V +10% -15%) at a
frequency of 50 Hz. It is not suitable for other types of supply. The maximum current consumption in normal
use is 200 mA.
Batteries
The battery used with the control panel must be a 12 V sealed lead-acid rechargeable battery of up to 7 Ahr
(plastic box) or 17 Ahr (metal box) capacity on the 2-44+ and 12 Ahr on the 2-20. The battery must be
positioned on the battery shelf. Wire in battery leads to panel terminals (red lead to Batt+, black lead to
Batt-). The battery leads must be connected to the battery observing terminal polarity and not left hanging
near the mains terminal block.
Fuses
The mains supply must be disconnected before opening the cabinet and changing the fuse. Replace the mains
fuse with the same type and rating. Refer to SECTION 15:  SPECIFICATIONS.

Galaxy 2 Series Installation Manual
Connecting the Galaxy 2 Series to the PSTN
The Telecommunications Network Voltage (TNV) port (terminals A and B on TB1) must be permanently
connected (hard-wired) to the PSTN via a BT master socket, refer to Figure 3.
Note: If the BT master socket is the newer type (
NTE5/CTE5), then the connection can be carried out by the
installation engineer. If the BT master socket is not an 
NTE5/CTE5, then the network operator must make the
connection.
Figure 3. Connecting the Galaxy 2 Series to the PSTN
NOTES:1. Terminals 2 and 5 on the BT Master Socket must be hard-wired to the A and B terminals
(TB1)on the Galaxy 2 Series PCB. The connection is polarity independent.
2. It is strongly recommended that the Galaxy 2 Series panel is the only device on the line.
3. If another device is to be connected to the line, connect the PHONE terminals on the PCB
to terminals 2 and 5 on a second BT Master Socket and connect the additional devices to
the second socket.
Using cable suitable for connection to 2.8 mm diameter screw terminals, strip back approximately 20 mm of
the outer sheath and then remove approximately 4 mm of the insulation from the wires to be connected to the
Galaxy 2 Series.
Connect terminals 2 and 5 on the BT Master socket across the A and B terminals (TB1) on the Galaxy 2
Series, see Figure 3.
Private Branch Exchange (PBX) Approval
The Galaxy 2 Series may be used with some analogue PBX exchanges. The correct operation of the Galaxy
2 Series cannot be guaranteed under all possible conditions of connection to compatible PBXs.

Galaxy 2 Series Installation Manual
REN and SEN Numbers
It is possible to simultaneously connect a number of items to one line of the PSTN. The limit is determined by
summing the Ringer Equivalence Number (REN) shown on each item of apparatus, ensuring that the sum of
RENs is not more than four.
The REN of the Galaxy 2 Series is one (1).
Assume that all British Telecom equipment has a REN of one unless otherwise marked.
More than one item of series apparatus may be connected to the Galaxy 2 Series ports marked phone. This is
limited by summing the Series Equivalence Number (SEN) shown on each item of series connected apparatus,
ensuring that the sum of the SENs is not more than one (1). The total series resistance, including cabling, must
not exceed 50 Ohms.
• The SEN of the Galaxy 2 Series is 0.3.
• Nominal series resistance is 90 milli-ohms.
• Nominal insertion loss is 0.1 dB.
It is recommended that the PSTN should have the following facilities:
• Outgoing calls only (when used as dialler only).
• Direct exchange.
• Tone dialling.
