Power Supply Unit

The Galaxy Dimension Power Supply Unit is available in 2 variants.
The Galaxy Power RIO consists of a Power Block and a Control Unit that includes an on-board RIO.
The Galaxy Power Unit consists of a Power Block and a Control Unit without the on-board RIO.
WARNING: There are lethal voltages present in the Power Block. Remove mains power from
the Power Block before handling it.
Each variant can be integrated with all Galaxy Dimension control panels. The number of Power Units or
Power RIO's that can be used on a system is limited by the number of RIO's that can be added to each panel.

Configuration

The Galaxy Power Supply Unit (PSU) consists of 2 modules, the Power Block and the Control Unit. The
PSU can be connected to the Galaxy Dimension control panel via the RS485 (AB) line. The PSU can be used
in place of a standard RIO to overcome power problems that arise when the additional RIO is fitted distant to
the control panel.
A 6-way jumper lead connects the Power Block to the Control Unit.
The PSU has 8 zones and 4 outputs. Each PSU takes one of the 4 RIO address (2 - 5). Addressing is identi-
cal to that described for RIO Modules.
The 4 outputs are switched 0V (0V active). Without the jumper links (LK1-4) fitted, the outputs will float in
the OFF state. They can apply a +12V signal, if required, by fitting the appropriate pull-up jumper supplied.
LK5 will short out the off-wall tamper if it is not used.
The SLAVE and E/E links must be in place for normal operation.
FAULT OP AC: This is an open collector transistor which is normally off. The output is activated by an AC
failure.
FAULT OP BAT:This is an open collector transistor which is normally off. The output is activated by a
Battery Low or Battery Fail condition.
FAULT OP POWER: This is an open collector transistor which is normally off. The output is activated by
low voltage present in +12V1, +12V2 or +14.5V.
