Single Zone Expander
(RP128EZ01)
The RISCO RP128EZ01 is a Single Zone Expander that enables to connect any detector to RISCO system
BUS. Using the BUS connection you can ease your installation by connecting any detector in parallel
connections from any point along the wiring route. In addition you can define any detector with one of
the following zone terminations supported by the panel: NO, NC, EOL, DEOL, TEOL.
The following instructions explain how to connect to the RP128EZ01 the ProSYS.
Notes:
1. Up to 32 Single Zone Expanders can be installed on the ProSYS main BUS.
2. Up to 128 Single Zone Expanders can be assigned to the ProSYS using the BUS Zone Expander.
The following instructions explain how to connect a detector to the ProSYS BUS using the RP128EZ01.
