Nittan Evolution SCI-6 Wall Mounted Short Circuit Isolator (S.C.I.-6)

The SCI-5 and SCI-6 Short Circuit Isolators are designed for use within Nittan analogue-addressable fire alarm systems.

The SCI-6 version is built into a single gang electrical plate and is fully compatible with any single gang, surface or flush electrical mounting box.

Analogue-addressable systems are commonly wired in a loop configuration and a short circuit fault occurring on the loop wiring, without short circuit isolators, will inhibit signalling on that cable, effectively rendering the entire loop disabled.

However, installing Short Circuit Isolators on the loop; the section of wiring containing the short circuit may be isolated from the remainder of the loop, this limits the extent of the disablement to only that cable between two adjacent Short Circuit Isolators. The remainder of the loop may thus continue to function as normal.
