RUBEZH IZ-1-R3 loop isolator — buy in Tashkent

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

Areas of application

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.
