Fire alarm cable BITNER YnTKSY 2x2x0.8 100m — 2 pairs, conductor 0.8 mm, 100 m reel

BITNER YnTKSY 2x2x0.8 fire alarm cable on a 100 m reel is intended for indoor wiring of fire detection and alarm systems. The cable contains two twisted pairs with solid conductors of 0.8 mm diameter, arranged to ensure reliable transmission of low-voltage alarm and detector signals between sensors, control panels and notification devices. The compact multi-pair layout simplifies routing in trunking and conduits and reduces the number of separate runs required for small and medium installations.

Advantages

The construction with two twisted pairs lowers electromagnetic interference and crosstalk between circuits, improving signal integrity for addressable and conventional systems. The solid conductors provide stable terminations in screw and clamp-type connectors. Supplied on a 100 m reel, the cable is convenient for measured runs and reduces joints. The cable sheath and pair insulation are suitable for standard indoor environments where a dedicated fire alarm circuit is required.

Suitable for

• Wiring of fire detection and alarm systems in commercial and residential buildings
• Interconnection of smoke and heat detectors to control panels
• Low-voltage notification devices and sounder circuits
• Short to medium cable runs inside trunking, conduits, and cable ducts

Key specifications

• Pair configuration: 2 twisted pairs (2x2)
• Conductor diameter: 0.8 mm (solid conductors)
• Cable length on reel: 100 m
• Suitable environment: indoor installation
• Typical application: fire alarm and detection signal transmission

How to use

Plan the cable route avoiding sources of strong electromagnetic interference and high-temperature zones. Cut required length from the 100 m reel and strip the outer sheath and pair insulation carefully to expose conductors without nicking. Connect conductors to the correct terminals on detectors, control panels or sounders following the system wiring diagram and polarity requirements. Secure the cable along its route using appropriate clips or ties, ensuring bend radii are not exceeded and joints are minimized to preserve signal integrity.

Recommendations

Use this cable exclusively for low-voltage fire alarm circuits and comply with applicable local electrical and fire safety regulations. For longer runs, complex systems, or installations exposed to mechanical stress or moisture, consult system documentation or a qualified installer to confirm suitability or choose an alternative cable type designed for those conditions.
