- Loop isolator
- Protocols
- R3
- Application
- Short-circuit protection, addressable communication lines
The Rubezh IZ-1-R3 loop isolator protects addressable communication lines from short circuits in the Rubezh fire and security alarm systems based on the R3 protocol. When a short circuit occurs, the isolator automatically disconnects the damaged loop section, preserving the operability of the remaining devices on the addressable line. This is a critically important reliability element for sites where continuous operation of the security system is a mandatory requirement.
Advantages
- Protection against short circuits: automatically localizes the damaged section without affecting the healthy part of the line
- Preservation of system operability: in case of a short circuit on one section, the remaining devices continue to function
- R3 protocol: full compatibility with the addressable lines of Rubezh control panels and controllers
- Increased fault tolerance: a mandatory element for systems where downtime is unacceptable
- Compliance with standards: loop isolators are required by fire safety standards in addressable systems
- Simple installation: installed directly into the addressable line without complex configuration
Applications
- Addressable fire and security alarm systems: protection of communication lines between the control panel and addressable devices at extended sites
- Industrial enterprises: ensuring continuous operation of the fire alarm under conditions of possible mechanical cable damage
- Multi-story buildings: isolating loops by floor to prevent cascading failure
- Sites with increased reliability requirements: hospitals, data centers, continuous-cycle production
Frequently asked questions
Is it mandatory to install isolators in every addressable system?
Fire safety standards require the use of isolators in ring addressable lines; specific requirements depend on the project.
How does the isolator restore operation after a short circuit is eliminated?
After the short circuit is removed, the isolator automatically restores communication with the previously disconnected section.
How many isolators are needed per addressable line?
It is recommended to install an isolator before each group of devices or on each branch — SAT Solutions specialists will calculate the optimal layout.
