Description
The FireLite I300(A) Fault Isolator Module is used with FireLite’s addressable fire alarm control panels (FACPs). It protects the system against wire-to-wire short circuits on the SLC loop. The I300(A) should be placed between each device on the SLC loop to isolate a short-circuit problem between the modules. It is required for true Style 7 operation so that other devices can continue to operate normally if there is a short-circuit on the SLC.
Application
The Fault Isolator Modules should be spaced between groups of sensors in a loop to protect the rest of the loop. Use to contain short circuit problems within a section of a loop so that other sections can continue to work normally. The I300(A) supports up to 25 devices in-between isolators, except when using relay bases.
I300(A) Fault Isolator Module Features and Benefits
- Generally used at each T-tap branch. This limits the effect of short circuits on a branch to the devices on that branch in Style 4 loops.
- Isolates devices so they can continue to operate normally in the event of a short-circuit on the SLC in Style 7 operation.
- Powered by SLC loop directly, no external power required.
- Mounts in standard junction boxes
- Â LED blinks to indicate normal condition.
- Supports a maximum of 25 devices in-between isolators, except when using relay bases.
