Telecommunication station cable with PVC insulation and flame-retardant red PVC sheath, for use in fire protection systems. The cables are used primarily as transmission lines and power supply lines for line devices (sensors, line modules) in supervision lines of fire alarm systems, autonomous fire extinguishing and smoke exhaust control systems, they are used at the "0" moment of the fire (the moment of fire detection by the detection panel) . The cables are intended for signal transmission or triggering of auxiliary devices, which, in the event of fire detection, are activated by the fire alarm control panel (e.g. disconnection of comfort ventilation, bringing passenger lifts, switching off the power supply of the facility).
