TECHNOFLAME FOC-2-SLT-HFFR PH120/E30-E60 50/125 OM2 is fire resistant and water-proof fiber optic cable with one central loose tube (up to 6 fibres) intended for use in fire alarm and fire automatic control systems. Cable can be installed in the buildings, tunnels and underground.

Halogen-free cable, applied when higher safety in case of fire is required. The cable is flame retardant, its smoke emission in fire is low and released gases are not corrosive.

Fibreglass yarns armour provides enhanced protection against mechanical damages and rodent attack. It’s also prevent water from reaching the cable core.

The cables are certified by Scientific and Research Development Centre for Fire Protection (Centrum Naukowo-Badawcze Ochrony Przeciwpożarowej) at Józefów.

The cables are resistant to water in accordance with the standard PN-EN 50200 Annex E. TECHNOFLAME FOC-2-SLT-HFFR PH120/E30-E60 50/125 OM2 cables can be used in fire protected rooms with fixed pressure water spraying fire extinguishing systems (sprinkler zones).

The cables are suitable for indoor and outdoor installations.
