Application |
Standards |
| |
Halogen-free installation cable for transmission of fire alarm signals, with improved properties under fire. Electrostatic screen protects transmission circuits against external disturbing electromagnetic impacts.
Suitable for fixed installation in dry or damp premises where people and material goods need to be protected in case of fire. Recommended for public and industrial facilities where a lot of people is gathering, and for facilities of high material value.
Not for direct laying in ground or water, not for outdoor application (except when adequately protected against sunlight), not intended for supply purposes.
advantages:
- halogen-free, no release of toxic and corrosive gases under fire
- reduced smoke manifestation under fire
- no flame propagation in vertical cable bundle , flame retardant
