HTKSHekw Halogen-Free Telecommunication Cable for Fire Signalling Systems

Indoor Use with Low Smoke, Flame Retardant, and Enhanced Signal Integrity for Critical Fire Protection and Control Applications

$7.00

Application:

Halogen-free special cables for interconnecting station equipment, telephone and teletransmission equipment and data transmission devices by means of analogue and digital signals in control and signalling fire protections systems. The cables are used primarily as transmission and power suplly lines for line equipment (sensors, linear modules) in supervised lines of fire signalling systems and autonomous fire extinguisher and smoke removal control systems. The cables are incorporated in systems used atthe „0" moment of fire origination (the moment of fire detection by the central detector). The cables can be used for transmitting trigger signals or conditions to auxiliary devices, which are activated by the central fire signalling mechanism upon detection of a fire (e.g. disconnection of a residential ventilation system, downward movement of passenger lifts, switching off of the power supply of building). Static screen protects the cable against interferences of external magnetic fields.
