Do you have to use low smoke cable?
The use of LSOH cables is not a requirement of BS 7671 in domestic or Non-domestic buildings at present. The use of these cables is often subject to specification requirements rather than regulation. Regulations, however, may soon require such cables when installed in escape routes in certain buildings.
Can LSZH cable be used outdoors?
AFL’s Indoor/Outdoor Low Smoke Zero Halogen (LSZH) Breakout Cables are perfectly suited for rugged applications and installations requiring increased performance. These cables feature a durable IEC-compliant, zero halogen, UV and fungal resistant outer jacket.
What is a low smoke Ethernet cable?
On top of this they have the option of shielding to further protect the cable from interference. These categories of Ethernet cable, and shielding identifiers are how we work out what type of cable we need for a specific application.
What is low smoke Cat 6 cable?
Cat6 Low Smoke patch cables, or LSZH or LS0H, are manufactured using Low Smoke Zero Halogen UTP stranded cable. Each cat6 low smoke cable is fully moulded and fitted with high quality RJ45 connectors. Our Cat6 low smoke range includes. Cat6 Low Smoke patch cables.
Where is LSZH required?
The clearest uses for LSZH are confined spaces with large amounts of cables in close proximity to humans or sensitive electronic equipment. Submarines and ships are classic examples, which is why the military was one of the first adopters of LSZH standards.
Is LSZH cable fire resistant?
LSZH Fire Resistant (FR) Cable LSZH FR cable is a fire safety product, which means it not only reduces the spread of fire, it will maintain circuit integrity in the presence of fire.
Is LSHF the same as LSZH?
LSHF Cable – Low Smoke Halogen Free. LS0H Cable – Low Smoke 0 (zero) Halogen. LSZH – Low Smoke Zero Halogen.
Why is smoke cable low?
When burned, a low-smoke zero halogen cable emits a less optically dense smoke that releases at a lower rate. During a fire, a low-smoke cable is desirable because it reduces the amount and density of the smoke, which makes exiting a space easier for occupants as well as increases the safety of firefighting operations.
Is PVC low smoke?
The term “low-smoke, zero-halogen” describes two distinct properties of a cable compound. PVC — Polyvinyl chloride (vinyl), a general-purpose plastic jacket material used for cables. Features low in cost and flexible, PVC cable is widely used in applications such as computers, communications and low voltage wiring.
What is difference between fire resistant and flame retardant cable?
Flame resistive and flame retardant cables are being used increasingly due to their usefulness in the event of fire. A fire resistant cable will continue to function in the event of a fire and is also identified as a Circuit Integrity Cable. A flame retardant cable on the other hand will not propagate or convey a fire.
Why do you need a low smoke cable?
When burned, a low-smoke cable (also known as limited-smoke cable) emits a less optically dense smoke that releases at a lower rate. During a fire, a low-smoke cable is desirable because it reduces the amount and density of the smoke, which makes exiting a space easier for occupants as well as increases the safety of firefighting operations.
What are the regulations for fire escape cables?
Regulation 422.2.1 states that cables shall not encroach on escape routes unless they meet the requirements of BS EN 60332-3 and BS EN 61034-2. These standards require cables to be tested to verify reduced fire propagation and low smoke emissions.
Is the use of LSOH cables a requirement?
The use of LSOH cables is not a requirement of BS 7671 in domestic or Non-domestic buildings at present. The use of these cables is often subject to specification requirements rather than regulation. Regulations, however, may soon require such cables when installed in escape routes in certain buildings.
What are the different types of fire protection cables?
There are lots of acronyms for these types of cable and many are registered trademarks, examples below: 1 Low Smoke Zero Halogen (LS0H/LSZH) 2 Low Smoke Halogen Free (LSHF) 3 Halogen Free (HF) 4 Zero Halogen (ZH) 5 Low Smoke and Fume (LSF) 6 Zero Halogen Low Smoke (OHLS) and. 7 Halogen Free Flame Retardant (HFFR).
