FIRE ALARM CABLES-SINGLE CORE FIRE RESISTANT
These cables are designed for installations in trunking and conduits where a fire situation may pose a major hazard. Circuit integrity is
maintained and to achieve optimum performance such cables should be installed in metal conduits.
Adapted to EN 50525-3-41
Voltage rating : 450 / 750 V
Operating temperature : -20OC to + 90OC (the cable should not be flexed when the temperature is below 0OC)
Minimum Bending Radius : 8 x Overall diameter
Conductors : Stranded plain annealed copper conductor to BS EN 60228, class 2.
Insulation : Mica (fire resistant) tape covered by an extruded layer of cross - linked low smoke zero halogen (LS0H), insulating compound
*Sheathed version also available. Details available on request.
Circuit Integrity for installation in metal conduits : BS 6387 categories C, W & Z (when applied to a single cable)
Exceeds IEC 60331 - 3 hours at 750°C - when the test temperature was increased to 950°C, equivalent to BS 6387 category C
Acid Gas Emission : IEC 60754-1, BS EN 50267-2-1
Smoke Emission : IEC 61034, BS EN 50268
Flame Propagation : EN 60332-1, EN 60332-3, BS EN 50265, BS EN 50266
