The Tyco 545.800.004 LIM800 Ancililary Line Isolator Module is de signed to be used on all Tyco Minerva MX addressable loops. The LIM800 monitors the line condition and upon detection of a short circuit, it isolates the affected section while allowing the rest of the addressable loop to function normally.
The Tyco 545.800.004 ensures that on a looped addressable system a short circuit fault cannot disable more detection devices then would be lost on a conventional non-addressable system in accordance with the BS5839 Part 1.
