Syston 18/2 Fire Alarm Cable, Solid Unshielded, FAS FT4, 300 m (1000 ft)

Syston 18/2 fire alarm cable for fire protective signalling circuits, smoke detectors, strobes and sirens, pull stations, voice communication, initiating and notification circuits, and addressable control systems.

The FT4 riser rating covers vertical runs between floors as well as general building use. The jacket is sunlight resistant (UL 1581) for above-ground outdoor runs; Syston notes it is not a substitute for direct burial cable. It ships on a Syston RhinoPac spool, designed to keep cable from tangling and to protect it from crushing and water damage. A ripcord under the jacket speeds up stripping. Ascending and descending footage markings make it easy to see how much cable is left. Legend markings let you label channels, rooms and zones.
