BUS Zone Expander
Model: RP128EZB
The BUS Zone Expander (BZE) enables to expand the number of bus detectors connected to the RISCO system to more
than 32 detectors and to improve bus performance.
Each BUS Zone Expander creates a separate bus loop that is used only for the bus detectors connected to it. The separate
bus loop increases the total system security in case a certain bus detector is sabotaged.
Each BUS Zone Expander can be defined to support 8, 16, 24 or 32 bus detectors.
The following instructions explain how to connect a bus detector to the system using the BUS Zone Expander.
Note: Communication with the BUS Zone Expander is supported by ProSYS ver. 7 and later and LightSYS. The BUS Zone Expander is
supported by Upload/Download software ver 3.2.x.x and later and Configuration Software.
Installation
Note: For maximum operation stability, it is best NOT to exceed a total of:
1. 300 meters (1000 feet) of wiring from the BUS Zone Expander to the panel
2. 300 meters (1000 feet) of wiring from the BUS Zone Expander to the last bus detector
