Zones
The Galaxy 2–20 has 12 on-board zones expandable to 20 (RS485 bus).
The Galaxy 2–44+ has 12 on-board zones expandable to 44 (RS485 bus) or 36 (ECP bus).
The zones on the Galaxy 2 Series can function in one of three modes; Normal Closed, Double Balanced and
U.S. End of line. Zone wiring for the three modes are illustrated in the following three Figures:
    
 
 
 
 
 
 
1K1K
Figure 6. Zone wiring for Normal Closed Zones
Figure 7. Zone wiring for Double Balanced Zones
Figure 8. Zone wiring for US EOL Zones
The mode of operation for the zones is programmed from menu option 51.46 = Parameters. Zone Resist-
ance. The default zone resistors are 1k ohm. However this can be changed in option 51.46. It is strongly
recommended that the maximum cable run on each zone is 100 m.
Zone Links
The bell tamper circuit can be shorted using the Links provided in the installation kit.  If the zones are pro-
grammed as Double Balanced or U.S. End of Line, fit a 1k resistor across the zone and not the zone link. It is
strongly recommended that this be done if any of the circuits are not to be used.

Wiring Zones
The zones on Galaxy 2 Series panels are defaulted as double balanced.  Each zone is 1 kΩ closed and 2 kΩ
open. The transition from 1 to 2 kΩ generates an alarm condition.  Refer to Table 2 for details of the zone
resistance and resulting conditions.
NOTE:The circuit debounce time (the period the zone must remain open to register a change in condition) is
300 milliseconds by default.
Table 2. Zone Resistance
Multiple detectors can be wired into a single zone. The maximum number of detectors that can be connected
to a single zone is 10.
Wiring Keyswitches
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.
The wiring of the keyswitch is shown in  Figure 9.
Wiring Push-Set 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:For push-set zones to operate, parameter 51.08, Exit Terminate, must be set up.
The wiring of the terminator is shown in the following Figure .

Zone Addresses
Each zone on the Galaxy 2 Series has a 4-digit address. For example: 1004, 1058. The address is made up of
three reference numbers as shown in the following figure:
Figure 10. Zone Addresses
The example above, 1004,  is the detector connected to line 1, RIO 00, zone 4.
Zone Numbering System
The numbering system is as follows:
1. The first number is the Galaxy 2 Series Panel line that the RIO/Expander is connected to. This will
always be 1.
2. The next two numbers refer to the address of the RIO/Expander that the zone is on.
00 = On board RIO
01 = On board RIO
02 = RIO/Expander 1
03 = RIO/Expander 2
04 = RIO/Expander 3
05 = RIO 4
3. The last number is the actual zone on the RIO/Expander 1-8. Therefore the valid zone numbers are:
1001 - 1004
1011 - 1018
1021 - 1028
1031 - 1038
1041 - 1048
1051 - 1058
This gives a total of 44 zones.

Outputs
The Galaxy 2 Series has four on-board outputs;  Bells, Strobe, Speaker and Set. The format of the address-
ing of the outputs is similar to zones. The addresses of these outputs are as follows:
Table 3. Output Addresses
Output Addresses
Table 4. Trigger Output Addresses *NOTE:Output 1002 - This output is configured as a 16 Ohm speaker driver (AC signal). The speaker
should be connected between this output and +12V. The speaker Entry/Exit volume is controlled
by parameter 51.10. It is possible to reprogram the output to operate as a normal switched
negative output by programming parameter 51.15 to 0=Switch DC. However, when it is
reprogrammed to operate as Switch DC, a loudspeaker should never be connected directly to
this terminal otherwise damage may result. Always ensure that this parameter is set to 1=SPK
Driver, before connecting a loudspeaker.
Trigger Header
The Trigger Header on the Galaxy 2 Series is a set of pins, which consists of programmable outputs for an
external communication module. The connection is via an optional ribbon cable (Part No. A229).
Trig 1-8
There are eight trigger outputs, which are intended as communication triggers, but can be used for any pur-
pose. By default these outputs are programmed as positive. They are designed to sink current (to 0V) not
source current (from 12V). The addresses of these outputs are as follows:
Output

Figure 12. Daisy-chain Configuration
Data Buses
Two separate data buses are available to connect the Galaxy 2–44+ panel to its peripherals.
Communication between the Galaxy 2–44+ control panel and the peripherals attached to it (see Figure 1),
takes place on the data bus. The control panel constantly monitors the peripherals attached to it. A break in
the communication from any of the peripherals generates a tamper alarm.
RS485 Wiring Configurations
The system must be wired in a daisy-chain configuration.  That is the A line from the previous peripheral is
connected to the A terminal of the current peripheral and then on to the A line of the next peripheral.
The RS485 (AB) line must have a 680 Ω resistor fitted across the A and B terminals of the last peripheral on
the line.Figure 11. Trigger Header
Inputs
Line Fault: This input tells the panel that the communicator has a telephone line fault (active low).
Reset:This input from the communicator resets the panel on a low to high signal (negative removed).
Supply
A 100 mA, 12V output is also provided. The output is fused by the on-board AUX FUSE (F2).

RS485 Wiring Recommendations
1. The system must be wired in a daisy-chain configuration. Spur and star configurations must not be used.
2. The recommended cable used to connect the RS485 (AB) line is twisted pair screened cable (Belden
8723 equivalent). However, for cable runs of less than 100m in normal environments, standard 4-core
cable can normally be used.
3. There must only be a single AB pair of wires in each of the cables.
4. The power supply in the Galaxy 2 Series control panel and remote power supplies must not be connected
in parallel.
5. The 0V of all remote power supplies must be connected in common to the 0V of the Galaxy 2 Series
control panel.
6. Ensure that any extension loudspeakers are not wired in the same cable as an AB pair of wires.
7. Where possible, ensure that the AB cable is at least 30 centimetres away from any other cables.
8. Where possible, ensure that the AB  cable does not run parallel to other cables for extended
distances (maximum five metres).
9. The maximum length of cable run is one kilometre. If  two lines are connected, both ends must be terminated with 680 Ω resistors and the appropriate End OF
Line (EOL)  resistor on the control panel PCB must be disconnected by removal of  link LK1.
