Halogen-free installation cables maintaining function are used in applications with high safety requirements and where a certain functional maintenance must be assured in the event of fire.

Halogen-free cables with enhanced characteristics in the event of fire are used for the protection of high material assets and for compliance with safety requirements. In case of fire, these cables inhibit the propaqation of the flames whereby the development of smoke is extremely low. No corrosive gases are emitted in the event of fire. Products of decomposition having harmful and corrosive effects on buildings, installations and equipment can be prevented.

The static screen (St) of plastic-coated metal foil protects the circuits from external electrical interference for compliance with specified capacitance unbalance values and to assure an exact pulse transmission.

These cables are used for installation in dry and moist rooms inside buildings, on and beneath plaster and in exceptional circumstances for outdoor applications provided there is adequate protection from the effects of sunshine.

The use of installation cables for power cable applications and underground installation is not permitted.

Characteristic features

•  A real alternative to customary PVC cables.
•  Low caloric values-refer to the Table of Technical Guidelines.
•  Maintenance of function > 90 minutes (E90); insulation integrity > 180 minutes (FE 180).

Installation Notes

•  Correct installation of the cable, assembly and operational set-up are prerequisites for the service life of the cable.
•  Allowance shall be made for acceleration, traversing rate, traverse distance, bending radius and ambient air temperature in the trailing chain application, refer also to the installation notes given in the Technical Guidelines.

Durability

•  Chemical resistance properties of H (halogen-free) materials refer also to the Table of Technical Guidelines.

* ) Cables with 2 pairs laid up as a star quad

Note
Available upon request as fire alarm cable with red sheath and imprint.

Core identification

Winding 1 :	a-core blue b-core red		star quad
Winding 2 :	a-core grey b-core yellow

The bundles are identified by the colours of the rings on the core insulation and the arrangement of the colour coded rings in groups. The groups of rings are approx. 60 mm. Apart.

For cables with more than 12 bundles, bundles no. 13 and onwards are assigned coloured spirals

Method of counting

The bundles are counted from the centre outwards.

Colour coded rings, ring groups and bundle spirals
