Indoor Telephone and Fire Alarm cables

Indoor Telephone and Fire Alarm cables

They are produced according to TS IEC 60189-2 standards and they are used in fixed applications, switch board or subscriber systems.

They have types with PVC, HFFR outer sheath also with annealed, tinned conductor, screened and unscreened types.

Types produced with HFFR content catch fire in a prolonged period of time during fire and fire mostly extinguishes in the end. They have low smoke density and they do not emit poisonous and corrosive gasses during a fire. They are used in buildings where there is intense human population.

Fire alarm cables are used  for transmitting signals and data for indoor fixed installations. Fire alarm cables can be preferred in security and indoor telephone systems. Static screen in these cables  protects the signal from external electrical interference and provides continuity in signal quality.
