ire rated cables are cables that are specifically designed to maintain circuit integrity in the event of a fire. These cables are commonly used in fire alarm and detection systems to ensure that the system remains operational in case of a fire.
Here are some of the characteristics of fire rated cables:
Fire resistance: Fire rated cables are designed to withstand high temperatures and flames. They are typically made with materials that do not contribute to the spread of fire.
Circuit integrity: Fire rated cables are designed to maintain circuit integrity even when exposed to fire. This means that the cable can still transmit signals even when exposed to high temperatures and flames.
Durability: Fire rated cables are typically more durable than standard cables. They are designed to withstand mechanical stress and can resist damage from impact, crushing, and bending.
Low smoke and zero halogen: Some fire rated cables are also designed to emit low smoke and zero halogen in the event of a fire. This can help prevent the spread of toxic fumes and reduce the risk of injury or death.
Fire rated cables are typically used in critical circuits, such as fire alarm and detection systems, emergency lighting, and communication systems. It is important to ensure that these cables are properly installed and tested to ensure that they can effectively provide power and signal transmission in the event of a fire.
