DFS Enhanced 120

Fire alarm cable, 300/500V

halogen-free, with improved fire characteristics,
BS 7629-1 and BS 5839-1:2013 Clause 26.2e

1 Conductor: solid copper wire
2 Insulation: EN 50363-5, fire resistant, low smoke, zero halogen compound
3 Drain wire: tinned copper circuit protection conductor (earth wire)
4 Shielding: Aluminium foil with a copolymer backing, halogen-free,
   bonded to the outer sheath
5 Sheath: FRNC/LSZH


Cable for fire alarm systems and emergency lighting.
For permament installation in buildings. Suitable for use in Hazardous Areas Zones 1 and 2.
Optimized for fast termination: The aluminium foil is bonded to the inside of the sheath by a copolymer backing. So it is removed together with the sheath when terminating.
Permitted operating temperature at conductor of +90˚C.

Insulation:Special compound, BS EN 50363-5
Core colours:HD 308 S2 and BS 7629-1
Shielding:Aluminium foil and tinned copper circuit protection conductor
(earth wire), IEC 60228, EN 60228
Sheath:Polyolefin compound, BS 7655-6.1, LTS3
Sheath colour:Red or white
Nominal voltage:300/500V                              
Test voltage:2000V, 50Hz 
Minimum bending radius during and permanent installation:6 x D (D = outer diameter)
Operating temperaturepermanent installation:-40°C to +90°C
 during installation:0°C to +70°C
