WHEN WE SHOULD USE FIRE-RESISTANT CABLES

In environments with high temperatures and the possibility of fire and explosion, or areas where fire alarm and smoke alarm systems are installed, it is necessary to use fire-resistant cables to ensure safety and limit damage to people and assets. These fire-resistant control cables need to meet special standards.

• Fire-resistant control cable is commonly used in the entire fire alarm system of construction works, including Buildings, factories, apartments, commercial centers, etc.

• Fire-resistant cables have the role of connecting with warning devices in buildings and factories, thereby detecting fire signs such as smoke detectors, heat detectors, gas detectors, fire detectors, and fire alarm sirens or exit lights.

• For the model of manufacturing plants, specialized fire-resistant cables are installed in high-temperature environments, and production areas containing dangerous substances or chemicals capable of causing explosions.

2. What standards do fire-resistant cables need to meet?

There are many standards to test the safety and operability of fire-resistant control cables. It ensures that the cables can withstand the maximum temperature, suitable for use in production and installation environments. Some typical and important standards fire-resistant cables need to meet such as

• DIN VDE 0472 part 814

• IEC 60331

• LPCB certified

• BS 6387:2013 (CWZ)

• BS 7629-1:2008

• BS 5839-1:2013 (Clause 26.2d Standard)

• EN 50200:2006 (Class PH30/PH120)

• EN 50200:2006 Annex E (30 mins)

• Halogen-free

• UV resistant

• Oil resistant with LS0H outer sheath type LTS3

• Flame retardant acc. to IEC 60332-1-2

• Flame test on bunched wires acc. to IEC 60332-3-24 cat. C

• Acid gas emission acc. to BS EN 50267-2-1 amd. 2

• Smoke density acc. to BS EN 61034-2

Following is the specific information of 3 typical fire-resistant cables, including HELUTHERM® FR BS 7629 (Partno. 11007368), (NHXH-FE 180/E 30 (part no. 52714) and ((NHXH-FE) 180/E 90 (part no. 53032).

This type of fire alarm cable is used for systems with fire detection functions or emergency lighting systems in buildings, offices, public works, and places where human safety is required. In addition, it can be installed where high-end equipment may fail due to exposure to Acid-generating gas.
