Section 2: OPTIONAL MODULES

Galaxy Remote Input Output (RIO) Module

A Galaxy RIO module can be connected to the Galaxy 16 and 16 plus to expand
the system by eight zones and four outputs.

Figure 2.1 Galaxy RIO Module PCB Layout.

RIO Tamper

Switch SW2 on the RIO module acts as a tamper if Link 1 is missing (absent by
default). Removal of the lid from the RIO enclosure activates the RIO tamper
alarm if the system is not in Engineer Mode. The tamper switch can be by-
passed by fitting a 0 W link to LK1.

Addressing the RIO

The Galaxy RIO must be addressed as 1. It must be addressed before it is
connected to the power supply, the address is selected using the 16-way rotary
switch (SW1), refer to Figure 2.1 Galaxy RIO Module PCB Layout.

Connecting the RIO

The RIO can only be connected to the system while Engineer Mode is
accessed. It is strongly recommended that the AB line of the Galaxy RIO is
wired in parallel (daisy-chain configuration) with the AB line of any keypads
connected to the system. The RIO requires 12 V d.c. (range 10.5 V to 16.0 V)
and 50 mA. This can be supplied from the control panel power supply or from a
remote power supply if the distance causes a large voltage drop on the cable.
Note: A 3 A Smart PSU (part number P015) can be fitted in place of a RIO and
remote power supply.
The connections to the RIO terminals are given in Table 2.1 Galaxy RIO
Connections.
