DESIGNATION
Cables for fire safety and fire alarm systems (hereinafter - "cables") are designed for single and group cabling for alternating voltage of up to 300 V and up to 10 kHz frequency or direct voltage of 420 V in fire-safety systems, fire and security alarm systems, fire detection systems, fire warning and evacuation control systems, emergency lighting on evacuation routes, emergency ventilation and smoke protection systems, automatic fire extinguishing systems and in other systems keeping operational during 180 minutes in fire conditions as well as in the areas of increased fire risk (subway, industrial facilities, schools, hospitals, office buildings, high-rise buildings).
Cable models and their definitions shall correspond to the details specified in the table below:
