Description

Standards

  • National
    BS 6387 CWZ; BS 7846; BS 8519 cat. 3

Application:

Designed for use in large complex buildings like stadiums, airports, hospitals, hi-rise offices and residential buildings, fully meets requirements to maintain circuit integrity even through the most extreme fire conditions.

Built to release low levels of toxic fumes when burning, for use with fire safety engineering systems such as:

• fire alarm systems

• emergency lighting

• other systems which help to ensure the safest evacuation and assist in the firefighting stages of a fire.
