There are two types of wires are used in the fire alarm system which are slow smoldering wire and fast flaming wire which can determine the amount of time you have to escape before being overcome by smoke.

Only copper conductors can be used for fire alarm systems. You can use conductors of sizes 18 AWG and 16 AWG (installed in a raceway, enclosure, or listed cable) if they do not supply a load that exceeds the ampacities given in 402.5.

Fire alarm systems typically use a type of electrical wire known as "fire-rated" or "plenum-rated" wire, which is designed to resist heat and flames.

Fire alarm systems typically use a variety of wires, depending on their specific requirements and applications.

For example, power wires are used to provide electricity to the system, while communication wires are used to transmit signals between different components of the system.

In general, fire alarm systems require wires that are fire-resistant and can withstand high temperatures. One common type of wire used in fire alarm systems is known as "plenum-rated wire," which has a special coating that is designed to prevent the spread of fire and smoke.

The specific type of wire used in a fire alarm system will depend on factors such as the size and complexity of the system, local building codes and regulations, and the preferences of the system designer or installer. It's important to consult with a qualified fire alarm system professional to determine the appropriate wiring for a specific application.
