The Dahua DHI-HY-1022R is the HY-series panel version that supports a ring loop. A ring topology means the communication line is closed and powered from both ends: if the cable is cut at one point, the system keeps polling every detector instead of losing part of the site. This configuration is chosen where fire alarm downtime is unacceptable.
Advantages
- The ring loop survives a single cable break — critical for facilities that never stop
- Addressable identification: the panel names the specific device, not a zone covering a dozen rooms
- Automatic line diagnostics pinpointing the fault location — repairs take hours, not days of searching
- Control of alarms, smoke extraction and building services through HY-series addressable modules
- Event log for reporting to supervisory authorities
Applications
- Continuous-process manufacturing plants
- Hotels, hospitals and buildings occupied around the clock
- Data centers, server rooms and areas with expensive equipment
- Large retail and logistics complexes
Frequently asked questions
What does a ring loop actually give you?
If the cable breaks at one point, the panel keeps polling all devices from the other side of the ring. A radial loop loses everything beyond the break.
Can an existing site be converted to a ring layout?
Yes, but the loop must be re-run as a ring and the panel replaced. Our engineers assess the scope against the current design.
Is the panel compatible with third-party detectors?
It works with Dahua HY-series addressable devices: detectors, input/output modules, sounders and loop isolators.
