fire emergency, standard cables fail quickly as insulation burns away and conductors short-circuit. Firecross fire resistant cables are constructed with specialized mica tape barriers and fire-resistant insulation that maintain circuit integrity even when directly exposed to flames. This ensures fire alarms continue sounding, emergency lighting remains operational, voice communication systems broadcast evacuation instructions, and lift doors remain controllable—all critical functions that save lives during building evacuations.
