Quick Setup
Section 1: Quick Setup
T o quickly set up a Galaxy 3 Series control panel for programming follow these simple steps:
1. Connect a 1k Ω (1%) resistor across each of the zones on the panel and any RIO’ s (if connected).
2. Ensure that the tamper return loop — the terminal marked as AUX T AMP on the PCB — is a complete
loop.
NOTE: This is factory set as a completed loop with a 0 V return.
3. Connect one of the keypads to the AB LINE terminals on the control panel. The Galaxy 3-48 has
one AB line; the Galaxy 3-144 has two AB lines; the Galaxy 3-520 has four AB lines (when an
RS485 Expansion Module is fitted).
NOTE: G3-48 - There is one AB LINE terminal on the control panel PCB.
NOTE: G3-144/G3-520 - There are two AB LINE terminals on the control panel PCB.

Installation Recommendations
Galaxy 3 Series Installation Manual
System Installation and Wiring
The installation and wiring must be performed by a competent engineer. For permanently connected equipment, a readily accessible disconnect device must be incorporated in the fixed wiring having contact separation
of at least 3 mm on each pole. The Galaxy 3 Series control panel must be connected to the a.c. mains supply
(230/240 Va.c. 50 Hz) via a fused connection outlet.
The fuse in the mains outlet must not exceed 3A.
WARNING:A means of isolation from the mains supply must be provided within 2 metres of
the control panel. Where live and neutral supplies can be identified, a fused spur
with a 3 amp fuse, must be fitted on the live circuit. Where live and neutral circuits
cannot be reliably identified, 3 amp fuses must be fitted to both circuits.
Route the mains cable through the hole on the right hand side of the enclosure base. Securely anchor the
cable to the box using the tie-wrap as shown in the following Figure:

Secure the panel base to the wall using three 1.5" No. 8 round head steel screws through the holes provided.
The mains cable used must be a three core type (with green/yellow earth insulation) of adequate current
carrying capacity .
NOTE: The mains cable must satisfy the requirements stated in BS6500.
Connect the mains cable to the mains terminal block as follows:
•blue wire to the terminal marked N (Neutral)
•green/yellow wire to the terminal marked (Earth)
•brown wire to the terminal marked L (Live)
NOTE: No other connections to the mains connector are permitted.
All wiring must be in accordance with the latest edition of the IEE W iring Regulations, BS7671 (Requirements
for Electrical Installations).

Connecting the Galaxy 3 Series to the PSTN
The T elecommunications Network V oltage (TNV) port (terminals A and B on PCB) must be permanently
connected (hard-wired) to the PSTN via a BT master socket, refer to Figure 2-7.
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 2-7. Connecting the Galaxy 3 Series to the PSTN
NOTES:1.T erminals 2 and 5 on the BT Master Socket must be hard-wired to LINE A and B
terminals on the Galaxy 3 Series PCB. The connection is polarity independent.
2.It is strongly recommended that the Galaxy 3 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.
There are two methods of connecting the on-board T elecom Module to the PSTN:
Method 1
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 3 Series PCB.
Connect terminals 2 and 5 on the BT Master socket across the LINE A and B terminals on the Galaxy 3
Series PCB, see Figure 2-7.
Method 2
Use a standard cable with RJ45 plug on one end and plug into the telecom socket on the Galaxy 3 Series
PCB. Connect the other end of the cable to the BT Master socket as described in Method 1.

Connecting Additional Telecom Apparatus
A BT secondary socket, allows additional telecom apparatus to be connected in series with the on-board
telecom module. Connect the PHONE terminals A and B on the PCB to the terminals on the BT secondary
socket. See Figure 2-7.
Line Monitoring
Under normal idle state conditions, the on-board T elecom Module monitors the RS485 line. The communication status is indicated by the state of the red LED (LED1) as shown in the following table:

Memory
Galaxy 3 Series Installation Manual
Memory
The Galaxy 3 Series control panel is fitted with a memory chip with its own battery backup on the main PCB.
This allows the panel to retain the system configuration, programming details and the event log for up to a year
when both the mains power and standby battery have been disconnected. The memory backup battery must
be kept in place to retain the memory during a mains failure. Re-apply power, this is known as a warm start.
T o completely erase the system memory and return to the default settings, place a piece of thin card between
the retaining clip and the memory backup battery then remove all power to the PCB for one minute. Re-apply
power and remove the card. This is known as a cold start.
The memory backup battery shoud be replaced every 5 years.
CAUTION:There is a risk of explosion if the battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
CAUTION:Do not overstress the retaining clip when removing and installing the backup
battery. The clip must maintain a firm pressure on the backup battery at all times.
RS485 Data Communication Bus (AB Lines)
Communication between the Galaxy control panels and the modules attached to the system takes place on the
AB lines. The communication protocol is RS 485 format. The control panel constantly monitors the modules
attached to it. A break in the communication from any of the modules generates a module tamper alarm
RS485 Wiring Configurations
The system must be wired in a daisy-chain configuration. That is the A line from the previous module is
connected to the A terminal of the current module and then on to the A line of the next module.
The RS485 (AB) line must have a 680 Ω resistor fitted across the A and B terminals of the last module on the
line. If two lines are connected, both ends must be terminated with 680 Ω resistors and the appropriate link
(LK3 or LK5) removed.

Wiring Keyswitches
Latching or spring loaded keyswitches can be used to set and unset the Galaxy panels; option 52 = PROGRAM ZONES has provision to accommodate both types of transition.
If the keyswitch latches, the transition from 1 kΩ to 2 kΩ initiates the setting procedure of an unset system,
the transition from 2 kΩ to 1 kΩ instantly unsets a set system. If the system is already set, then the transition
from 1 kΩ to 2 kΩ has no effect. If the system is unset, the transition from 2 kΩ to 1 kΩ has no effect. This
is programmed as a Keyswitch in the PROGRAM ZONES option.
If the keyswitch is spring-loaded (returns to its normal position), the transition from 1 kΩ to 2 kΩ initiates the
setting procedure of an unset system and instantly unsets a set system, the transition from 2 kΩ to 1 kΩ - the
return to the normal position - has no effect. This is programmed as a Keyswitch in the PROGRAMZONES option.

Wiring T erminator Buttons
Zones programmed as Push-Set (terminator) buttons can be open going closed (2 kΩ to 1 kΩ) or closed
going open (1 kΩ to 2 kΩ). The first activation of the terminator button initialises its status to the system.
NOTE: The first activation of a terminator may not set the system as this can be the initialisation routine. If
the system continues setting, push the button again. The system will set on the second push. This
initialisation only occurs on the first setting. All subsequent setting routines set on the first push of the
terminator.
The wiring of the terminator and keyswitch zone type is shown in the following figure:

Output Applications
Output Applications
The outputs on the Galaxy panels, with the exception of the SPCO relay output, are transistorised outputs;
negative applied (positive removed) by default. These supply up to 400 mA and can be used to drive the
necessary output devices.
NOTE:The polarity of each output can be changed using option 53 = PROGRAM OUTPUTS

The relay output is a single pole change over; this can be used to drive output devices that require a clean set
of contacts, isolated from the output voltage.
