TELECOMMUNICATIONS CABLE FOR FIRE ALARM SYSTEMS IN THE INFRASTRUCTURE AND CONSTRUCTION INDUSTRY
Telecommunication cable for fire alarm systems is commonly referred to as “telecommunication cable”. This is a general term for two types of cables: fiber optic cable and copper core cable. Both types of cables have the function of transmitting information efficiently.
Among them, fiber optic cable is a type of cable that transmits signals using light. Therefore, it provides stable signal transmission capability, suitable for supporting signal connections over long distances. Depending on the material structure, fiber optic cable is divided into two types: GOF (Glass Optical Fiber) made of glass material, and POF (Plastic Optical Fiber) made of plastic.
Next, copper cable is a type of cable with a core made of copper material, divided into 2 types: Twisted pair cable and coaxial cable. Among them, twisted pair cable has superior ability in anti-electromagnetic interference radiation, widely used in LAN network systems. Coaxial cable has a similar function to twisted pair cable, but it has 3 parts: copper core, insulation material, and outer layer of braided metal wire.
Fire alarm system cable is a control cable that connects the signal transmission line from the central system to the parts of the system including alarm lights, sirens, fire sprinkler systems, exit lights, automatic telephone dialers, etc. The specialized cable used for this system will ensure stable operation even in the event of a fire thanks to its fire resistance, and absolute limitation of fire spread. Even in the event of a fire, the cable can still transmit signals for a certain period of time.

Below are some typical telecommunication cable and fire alarm system cable lines.
1. OUTDOOR TELECOMMUNICATIONS CABLE
This is a telecommunications cable suitable for outdoor installation that connects telephone systems to the central office of each network. The cable is installed inside cable conduits and underground, with a cable sheath made of PE material that is waterproof, moisture-resistant, and effectively UV-resistant. The cable contains no halogens.
2. IN-HOUSE TELECOMMUNICATIONS CABLES
These are suitable cable models for installation inside the house, used for connecting signals in telephone stations, data transmission applications, and for peripheral device data processing computers. With high attenuation values, transmitting analog and digital signals up to 16 Mbit/s, the cable can be installed under gypsum board or fixed outside in areas without direct sunlight.
3. FIRE ALARM CABLE
These are specialized cables used in fire alarm systems. This type of cable is equipped with a static electricity shielding (St) to protect the entire signal transmission circuit from external electrical interference. The cable is suitable for installation in both dry and humid environments, inside or underneath gypsum layers, or fixed outdoor installations. The cable is completely halogen-free with fire-resistant and anti-flame outer casing material.
