Jan 18, 2023 · A fire alarm cable is a low-voltage cable used specifically for fire alarm signal transmission. These are the multiconductor cables with two or more copper conductors and thermoplastic insulation designed to withstand the impact of heat.
Aug 23, 2023 · These cables swiftly and accurately transmit signals from detectors, pull stations, and other devices to the central fire alarm control panel and notification appliances to ensure the reliable functions of fire alarm systems in the event of a fire emergency.
Sep 18, 2023 · Fire alarm cables are designed with special insulating plastics that produce less smoke when they burn, do not release toxins, and some are made to be self-extinguishing if they catch fire. Fire alarm cables are also usually manufactured with a red insulating jacket.

Standard types of wiring or cabling do not suffice for fire alarms. Various fire alarm cable constructions offer different degrees of heat and melting protection. Options include power-limited (PL) and non-power-limited (NPL), but the latter is less common. Power-limited options are connected to power supplies that limit the voltage and power going...
Shielded and unshielded are terms for different coatings on the exterior of cabling. While fire alarms can have these options, other types of cabling, such as signal and data cables, also have them. When needed, the shielding provides valuable protection from EMI that could impact connections, cause cross-talk between cables, and reduce radiation f...
Shielding consists of a form of conductive wrapping, typically aluminum or a similar metal. The conductive shielding blocks outside electromagnetic radiation from interfering with the signals passing through the wires inside the cable. The shielding also protects other cables nearby from EMI caused by the wires inside. The shielding’s design determ...
Using shielded or unshielded cabling for a fire alarm depends on the area you run the cabling in and the manufacturer’s requirements. Always check the manufacturer’s specifications for cabling size and shielding options first. Fire alarm systems are built around a specific wire size, making that the first and most important decision. Some manufactu...
The shielding in fire alarm cable does not provide additional heat protection. The insulation and jacket create cabling that is more resistant to heat damage. Choose the heat protection level based on where you will lay the cabling. Plenum cabling has a greater ability to resist heat due to its placement in locations where fire can spread. Never us...
The code for installing fire alarms requires conduit in specific situations, regardless of whether you use shielded or unshielded cabling. The locations where you install the cables determine whether you need conduit or raceways. NEC 760 requires using rigid nonmetallic conduits or metal racewaysfor running cabling through walls or floors. Addition...
