Key Features to Look for in Direct Burial Fire Alarm Cable

Fire alarm systems are essential for protecting lives and property. In the event of a fire, a reliable fire alarm cable is critical to ensure that the system functions properly. Direct burial fire alarm cable is designed to be installed underground, where it is protected from the elements and other hazards. When selecting direct burial fire alarm cable, there are several key features to consider.

Conductor Material

The conductor material is one of the most important factors to consider when selecting direct burial fire alarm cable. The most common conductor materials are copper and aluminum. Copper is a more expensive material, but it offers better conductivity and durability than aluminum. Aluminum is a less expensive material, but it is not as conductive or durable as copper.

Insulation Material

The insulation material is another important factor to consider when selecting direct burial fire alarm cable. The most common insulation materials are PVC and polyethylene. PVC is a less expensive material, but it is not as durable as polyethylene. Polyethylene is a more durable material, but it is more expensive than PVC.

Jacket Material

The jacket material is the outermost layer of the cable and protects the conductors and insulation from the elements. The most common jacket materials are PVC and polyethylene. PVC is a less expensive material, but it is not as durable as polyethylene. Polyethylene is a more durable material, but it is more expensive than PVC.

Direct Burial Rated

The cable should be specifically rated for direct burial, which means it has been designed to withstand the stresses of being buried underground. This includes resistance to moisture, chemicals, and rodents.

Fire Resistance

The cable should be fire-resistant to ensure that it can continue to function even in the event of a fire. This is especially important for cables that are installed in areas where there is a high risk of fire, such as warehouses or factories.

Sunlight Resistance

The cable should be sunlight-resistant to prevent the jacket from degrading over time. This is especially important for cables that are installed in areas where they will be exposed to direct sunlight.

Corrosion Resistance

The cable should be corrosion-resistant to prevent the conductors from corroding over time. This is especially important for cables that are installed in areas where they will be exposed to moisture or chemicals.

Physical Strength

The cable should be physically strong to withstand the stresses of being buried underground. This includes resistance to crushing, bending, and impact.

Warranty

The manufacturer should offer a warranty on the cable to protect you against defects. The warranty should cover the materials, workmanship, and performance of the cable.
