Removing and Replacing the Galaxy 2 Series PCB
NOTE:The metal box comes with the PCB installed. The PCB does not have to be removed to enable
access to the keyhole mounting slot (see Figure 17).
Mounting the Metal Enclosure Base
Use the keyhole slot in the metal box  to position the base. Three mounting screws (not provided) are required
to mount the metal base. Fix one of the screws into the mounting surface, this will be used for the top, keyhole
mounting hole....

Mk7 LCD Keypad/Keyprox
The Mk7 keypad is a 16 character alpha-numeric keypad used to program and set the Galaxy 2 Series. The
window display is spread over two lines.
The Mk7 keyprox is a standard keypad with a proximity card reader combined into one housing. This allows
dual function setting/unsetting ability from one station without the need for a separate card reader.
Keypad/Keyprox Installation
1. Remove the keypad from its packaging.
2. To attach the keypad to...

4. If you are using a wall-run cable for the keypad (A, B, +, -) position the cable behind the back plate in
the cable channels provided. The cable can be run in from either the top or the bottom of  the back plate.
Use a sharp tool to remove the plastic from the top or the bottom of the cable guides on the back plate
skirting.
CAUTION:Use of any screws other than No. 6 Pan-head can damage the keypad
mouldings.

Remote Input Output (RIO)
Galaxy RIO’s can be added to the RS485 Bus on the Galaxy 2 Series control panel. Each additional RIO
expands the system by eight zones and four outputs.
Figure 19. Galaxy RIO
Addressing the RIO
The Galaxy RIO must be given a unique address before it is connected to a power supply (see Table 8. RIO
Addresses).The address is selected using the 16-way Rotary Address Switch (SW1).

Link LK1 on the RIO, if altered when the module is powered down, modifies the RIO operation:
• LK1 - short circuit this to by-pass the RIO lid tamper switch SW2
Zones
The Galaxy RIO has eight programmable zones.  These default to INTRUDER.  Each zone is Double
Balance monitored with a 1 kΩ resistor in series with the zone detector and a 1 kΩ (1%) resistor in parallel
across the detector switch.  The change to 2 kΩ (1%) resistance registers the zone as open/alarm....

Power Supply Unit
The Galaxy 2 Series Power Supply Unit (PSU) is available in two variants.
The Galaxy Power Unit is a 3-ampere power supply. The Galaxy Power RIO is a Power Unit plus an on-
board Remote Input Output (RIO) module. Both variants are configured in the same way.
Configuration
The Galaxy Power Supply Unit (PSU) consists of two modules, the Power Block and the Control Unit. The
PSU can be connected to the Galaxy 2 Series...

Installation Instructions
The installation and wiring must be performed by a competent engineer. The Galaxy Power Supply Unit must
be connected to the a.c. mains supply (230/240 Va.c. 50Hz) via a fused connection outlet. The fuse in the
mains outlet must not exceed 3A.
The Galaxy Power Supply Unit comes installed in the metal enclosure base. The installation procedure of the
panel base is as follows:
1. Route the mains cable through the hole on the right hand side...

ECP Zone Expander (2–44+ Only)
This is an expander for use on panels that use the ECP communication Bus. Up to three zone expanders can
be fitted to the Galaxy 2–44+ panel. Each expander gives 8 extra hardwired zones and four programmable
outputs. An alternative expander gives four extra hardwired zones and no outputs.
