The Dahua DHI-HY-JX20 cable junction box provides a sealed connection for loop cables on site. Joints are the weakest link in a cable route: that is exactly where oxidation, moisture and loss of contact appear over time. The box protects the joint and keeps it accessible for inspection during maintenance.
Advantages
- A sealed joint protects contacts from moisture and oxidation
- Clean access to the splice during line diagnostics and repair
- Reduces the risk of false faults caused by a poor contact
- Simplifies branching and extending cable routes
- Compatible with HY-series fire alarm cabling
Applications
- Joining loop sections on long routes
- Transitions between blocks and floors
- Rooms with high humidity and temperature swings
- Repairing and extending existing cable lines
Frequently asked questions
Is it mandatory to use boxes for joints?
Open twisted joints are not permitted in fire alarm systems — connections are made in dedicated boxes, and this is checked at handover.
How many cables fit into one box?
Capacity depends on the model and cable cross-section. Our installers select boxes to suit the specific route.
Can the box be buried in concealed wiring?
Joints must remain accessible for maintenance, so boxes are placed where access is possible.
