Fires are not only a leading cause of structural damage but also pose a significant risk to human life, primarily due to the inhalation of toxic gases and the obscuration of escape routes by dense smoke. This underscores the critical need for effective fire management strategies, including the installation of resilient electrical systems.
Even the most advanced alarm and emergency systems may fail if fire compromises the integrity of their associated cabling. This vulnerability has prompted companies to invest heavily in the research and development of insulation materials and cables that Perform optimally under fire conditions. These advancements aim to minimize the emission of fumes and acidic gases, and maintain circuit integrity even during a fire.

Fire-resistant cables are designed to maintain their ability to transmit energy and signals during a fire for the minimum durations specified by relevant standards and regulations. These cables ensure continued operation of critical systems under extreme conditions. The behavior of cables in the presence of flames involves several vital aspects, primarily how the cable responds under these conditions. This has led to the distinction between two types of performance:
FLAME RETARDANT Flame retardant cables are designed to resist the spread of fire. However, these cables are typically destroyed during a fire, resulting in a loss of circuit integrity and causing all connected systems to fail. The primary function of flame retardant cables is to prevent the propagation of flames, not to maintain service during a fire.
FIRE RESISTANT Fire-resistant cables, on the other hand, are capable of maintaining circuit integrity and continue to operate in the presence of fire. This is crucial for systems such as fire alarms, emergency lighting, and voice alarm systems, which are vital for facilitating building evacuation, transmitting alarm signals, and activating extinguishing systems. Fire-resistant cables also possess flame-retardant properties, ensuring a higher level of security during a fire.
GAS EMISSION / SMOKE DENSITY Additional considerations in this context include the type and amount of gases emitted during combustion. Often, the danger in fire incidents stems not only from the flames themselves but also from the toxic gases released by the burning materials.
Polyvinyl Chloride (PVC) is a commonly used material for the insulation and jacketing of electrical cables due to its excellent flame-retardant properties. This effectiveness is largely due to the presence of chlorine, a flame suppressant within the compound. However, chlorine can be highly corrosive and toxic when burned, producing dense, heavy smoke. These are critical issues that need to be mitigated in fire scenarios. To address these concerns, important features to consider include: ■ Absence of Halogen (Acid Gas): Selecting materials that do not release halogenated acids or other toxic gases when exposed to fire. ■ Low Smoke Emission: To ensure these properties, specific tests aligned with various standards are conducted to verify the performance of these cables under fire conditions.
About Fire Alarm Cable
Description Even with the advances made in fire alarm systems and their associated detection equipment, most fire alarm cable technology has remained unchanged for decades. That said, the wires that go into an fire alarm system are as important as any wire. Fire alarm cables provide the basic framework upon which all building asset protection is based.
Applications
Fire cables: Fire Resistant Cables, Fire Alarm Cables, and Fire Safety Cables are used in fire monitoring, fire detection, power-limited fire alarm systems, smoke detectors, signaling, audio circuits, control circuits, fire protective circuits, and security systems.
What are fire resistant cable or fire alarm cable? At present, the cable industry is accustomed to flame retardant (Fire Retardant), halogen-free low smoke (Low Smoke & Halogen Free, LSOH) or low halogen low smoke (Low Smoke Fume, LSF), fire (Fire Resistant) and other fire-resistant (Fire Resistant) and other fire-resistant cables are collectively referred to as fire-resistant cables.
Flame Retardant Cable (Flame Retardant)
■ Flame retardant cables are characterized by delaying the spread of flame along the cable so that the fire does not expand. Because of its low cost, there is a large number of cable varieties used in fire prevention cables. Whether it is a single cable or a bundle of laying conditions, the cable is burned when the spread of flame can be controlled within a certain range, so you can avoid major disasters caused by the cable fire retardant, thus improving the level of fire protection of the cable line.
■ Halogen-free low-smoke cables are characterized not only by excellent flame retardant properties but also constitute low-smoke halogen-free cable materials that do not contain halogen, low corrosiveness, and toxicity during combustion, resulting in a very small amount of smoke, thus reducing the damage to the human body, equipment, and instruments, which is conducive to timely rescue in the event of a fire. Although halogen-free low-smoke flame retardant cables have excellent flame retardancy, corrosion resistance, and low smoke concentration, their mechanical and electrical properties are slightly worse than ordinary cables.
■ Low Halogen Low Smoke Flame Retardant Cable (LSF) has hydrogen chloride release and smoke concentration indicators between flame retardant cables and halogen-free low smoke flame retardant cables. Low Halogen (Low Halogen) cables also contain halogens in the material, but the content is lower. This type of cable is characterized not only by flame retardant properties but also in the combustion of smoke released less, the release of hydrogen chloride is lower. These low-halogen, low-smoke flame-retardant cables are generally processed with polyvinyl chloride (PVC) as the base material, together with high-efficiency flame retardants, HCL absorbers, and smoke suppressants. Therefore, this flame-retardant material significantly improves the burning performance of ordinary flame-retardant PVC materials.
Fire Resistant Cables ■ Fire-resistant cables can maintain normal operation for a certain period of time under the condition of flame burning and can maintain the integrity of the line (Circuit Intergrity). Fire-resistant cable combustion of acid gas smoke produced by the amount of small, fire-resistant, and flame retardant performance is greatly improved, especially in the case of combustion accompanied by water spray and mechanical shock vibration; the cable can still keep the line intact operation.
Flame retardant cable standards and ratings ■ The main technical criteria for fire safety of cables are the flame retardancy of CO2 cables, the density of smoke, and the toxicity of gases. ■ American fire protection standards are more concerned with the first two issues, but Europe and the United States have completely different views on fire safety. The traditional concept of the United States is that the root cause of the fire is the production of carbon monoxide (CO) gas and the subsequent combustion process of CO into CO2 heat release; therefore, controlling the amount of heat released during combustion can reduce the fire hazard. ■ The European tradition has been convinced that the release of halocarbonic acid (HCL) during combustion, the corrosiveness of the gas, the concentration of smoke, and the toxicity of the gas are the main factors determining the ability of people to get out of the fire scene safely.
Which standards should I consider when choosing a Fire Alarm or Security Cable? ■ Fire alarm cables play a very important role in fire alarm systems, and the requirements for fire alarm cables vary from countries and regions, we manufacture and sell the following mainstream standard fire alarm cables.You can choose according to your country's fire standard requirements. ■ European Standards ■ What is BS EN 50200 – Test method for cables about? ■ BS EN 50200 is a European Standard that specifies the test method for cables designed to have intrinsic resistance to fire and intended for use as emergency circuits for alarm, lighting, and communication purposes. ■ BS EN 50200 is applicable to cables for emergency circuits of rated voltage not exceeding 600 V/1 000 V, including those of rated voltage below 80 V and optical fibre cables. ■ NOTE: When the test method is used in support of EN 13501–3, it only applies to cables of less than 20 mm diameter, and, for metallic conductor cables, to those with conductor sizes up to and including 2,5 mm2.

USA Standards ■ UL1424: safety cables for Power-Limited Fire-Alarm Circuits ■ FPLP (Plenum Fire Alarm Power-Limited Cable) — Plenum cable is designed to be used in air ducts or the space between the structural ceiling and a drop-down ceiling. These cables (sometimes referred to as CMP or Communications Plenum Cable) have insulated jackets made of fire-resistant materials such as polyvinyl chloride (PVC) or fluorinated ethylene polymer (FEP) and are designed to restrict flame propagation to no more than five feet and limit the amount of smoke emitted during a fire. ■ FPLR (Riser Fire Alarm Power-Limited Cable) — Riser cable is designed for non-plenum environments, mainly in risers or vertical shafts. Riser cables meet the standards for levels of fire resistance installation necessary in a vertical riser or other non-plenum environments. These cables (sometimes referred to as CMR or Communications Riser Cable) are flame-retardant, intended to prevent the spread of fire from one floor to another. ■ FPL: Cables not intended for forced air ducts or building shafts, which may be used in cable trays, and cables for power-limited fire alarm circuits (limited use).
International standards (IEC) ■ IEC 60332-1-2: JB-YY, JB-Y(St)Y, JB-H(St)H fire alarm cable ■ The International Electrotechnical Commission (IEC) has formulated three standards to evaluate the flame retardant performance of cables: IEC60332-1, IEC60332-2, and IEC60332-3. IEC60332-1 and IEC60332-2 are used for assessing the flame retardant performance of single cables when they are laid out in an inclined and vertical manner (GB12666.3 and GB12666.4 standards), and IEC60332-3 (GB12666.5-90 standards) is used to evaluate the flame retardancy of bundled cables when they are burned vertically. ■ IEC60332-1/BS4066-1 Flame Retardant Rating (Flame Test On Single Vertical Insulated Wires/Cables) ■ This is the flame retardant standard for single cables. The test provides that a 60cm long specimen is fixed vertically in the front wall of the opening of the metal box, the flame length of 175mm propane burner from the upper part of the specimen from the fixed end of the position of 450mm flame cone and the cable at an angle of 45 degrees in contact with the specimen, if the specimen burns damage to the lower part of the distance from the fixed end of the test, is not more than 50mm, the test passes. ■ IEC60332-3/BS4066-3 Flame Retardant Rating (Flame Test On BunchedWires/Cables) ■ This is a flame retardant standard for bundled cables.
