Connecting the Output Module
The Output Module can only be connected to the system while engineer mode is accessed. The RS485 (AB)
line of the Output Module must be wired in parallel (daisy-chain configuration) with the RS485 (AB) line of
any keypads connected to the system. The Output Module requires 12 Vd.c. (range 10.5 to 15.0 V) and
250 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.

Connect the Output Module terminals as follows:
+ (12 V) - either control panel, keypad or remote power supply;
– (0 V) - either control panel, keypad or remote power supply;
S (Screen cable connect) - to control panel
A to the A terminal of the previous module (or control panel if Output module is the first on the line);
B to the B terminal of the previous module (or control panel if Output Module is the first on the line).
NOTE: If the Output Module is the last module on the line, connect a 680
Ω EOL resistor across the A and
B terminals.
Configuring the Output Module
The Output Module is configured into the system on exiting from engineering mode. The procedure is identical
to that for Galaxy RIO’s (see Configuring the RIO).

Connecting Outputs
The Output Module has two types of outputs:
Primary outputs are taken out on contacts CN1 to CN4. The maximum current load of outputs is
400 mA. The outputs are in open collector mode.
Secondary outputs are designed for connection of up to four external Relay Modules at connectors RM1-4
(see figure 3.4). This ensures that the maximum current load will increase up to 4 A/230 V ac per output. The
Relay Module does not require an external power supply.

NOTE: When connecting external comms devices, the secondary outputs must be used. The Relay Module
has to be used in the NC mode with a pull-up link from the +12V line to one of the relay contacts.
Number of Outputs
The number of active primary outputs are determined by setting the DIP switch. Each Output Module can
simulate up to four RIO’s depending on the DIP switch setting. It is therefore possible to program one Output
Module to have 16 active primary outputs. The following table shows the DIP switch settings.
