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:

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....

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...

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:

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...

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...

The built-in dialler allows signalling to an Alarm Receiving Centre (ARC), SMS signalling and remote servicing
from a PC.
LED’S
There are two LED’s on the Galaxy 2–44+  PCB. Pulsing of the red LED1 indicates an active telecommuni-
cations. Illumination of the green LED2 indicates the presence of AC mains supply.
There is one LED on the Galaxy 2–20 PCB. Pulsing of this LED indicates...
