RISCO Group LightSYS Ver 2.xx - Manual (Page 7)

Notes:
1. The main unit can support a maximum load of 1.4 Amp. If more current is required install
additional power supply modules (3 Amp max.).
2. On 3 AMP supervised power supplies and on the wireless expander, there are two
programmable outputs. These programmable outputs belong to the ‘Output’ family. These
outputs have dedicated DIP switches that identify the OUTPUT ID.
Maximum number of devices possible:
Total
Wired / BUS Expanders 3
BUS Zones 32
WL Zone Expanders 2
BUS Zones Expanders 4
Outputs Expanders 4
Keypads 4
1.5A or 3A Power Supply 4
BUS Sirens (ProSound / Lumin8) 4
2. Zone Inputs Connection
The following diagrams illustrate the various possible zone connections to the main unit or to
the 8 wired zones expander.

Notes:
1. For a zone with a tamper switch, you can use a double end-of-line resistor to save additional main
panel connections.
2. It is recommended that you use an end-of-line resistor at the far end of each hardwired zone (16 x
2.2K resistors are supplied).
3. In the LightSYS you have the ability to define separately the end-of-line resistance of the zones on
the main unit and of the wired zones for each eight-unit expander block (Quick key  ).
Selection is done by the software with the following available options:
