Selecting Fire Rated Security Cables
What cabling would you recommend for electronic security applications that demand cabling must be fire-rated?
When looking for fire-rated security cables seek out products sheathed with ethylene-methylacrylate, which resists fire and has low smoke emission. Along with this EMA cables are abrasion, oil and fuel resistant and able to function at 120 degrees C.
Not surprisingly, there are some installation considerations with toughened cable – including the fact they should be installed with a bend radius of 6 times the external diameter.
Pretty obviously the structures supporting fire resistant cable should also be fire resistant – that includes fixings. A key element of fire resistance is to ensure the cables have no connections, junctions or terminations in the ‘hot’ zone. You’ll also need to hunt up porcelain fuse holders.
