Risco Zone Bus Expander / Isolator - Suits LightSYS2
The Risco zone bus expander enables additional bus detectors to be connected to compatible Risco control panels. It also functions as a bus isolator, helping improve overall system security and communication performance.
Each expander creates a separate bus loop dedicated to connected detectors. This helps isolate faults and maintain system operation, while allowing flexible expansion of the system as requirements grow.
Key Features
- Expands the number of bus detectors on Risco systems.
- Supports up to 32 bus detectors per expander.
- Configurable support for 8, 16, 24 or 32 detectors.
- Creates a separate bus loop for connected detectors.
- Improves system security by isolating bus faults.
- Acts as a concentrator to improve bus performance.
- Supports long bus runs depending on cable type.

Frequently Asked Questions
- What is the purpose of a bus expander?
It allows additional bus detectors to be connected to the control panel, increasing system capacity. - Does this unit also act as an isolator?
Yes. Each expander creates a separate bus loop that helps isolate faults and improve system reliability. - How many detectors can be connected?
Each expander can be configured to support 8, 16, 24 or up to 32 bus detectors.
Additional Information
- Bus expanders are typically used in larger installations where multiple detectors are spread across different building areas.
- Using isolated bus loops can help maintain system functionality if a fault occurs on one branch.
- Correct cable selection and bus length planning are important for reliable communication.
