Fire safety cable electro base PRO BASE PB-1x2x2.50 LSZH shielded red 1x2x2.50m 100m

Fire safety cable electro base PRO BASE PB-1x2x2.50 LSZH shielded red 1x2x2.50m 100m is a purpose-built cable for life-safety and fire alarm installations. The cable features LSZH (low smoke zero halogen) insulation and an overall shield, providing reduced toxic emissions and improved electromagnetic compatibility during normal operation and in fire conditions. Supplied on a 100 m drum and identified by its red outer sheath, the cable is intended for fixed wiring between detectors, detector loops and control panels in buildings where both low smoke properties and shielding are required.

Advantages

The shielded LSZH construction minimizes smoke density and avoids halogen release in case of combustion, which helps protect people and sensitive equipment from corrosive gases. The overall shielding reduces interference from external electromagnetic sources and helps maintain signal integrity for alarm and detection circuits. The red sheath simplifies identification of fire safety circuits during installation and maintenance. The 100 m drum format supports longer runs without splices, reducing potential points of failure.

Suitable for

• Connecting smoke and heat detectors to fire alarm control panels
• Detector loop wiring in commercial and residential buildings
• Fixed installation in escape routes, stairwells and plant rooms
• Environments where low smoke and low halogen emissions are required

Key specifications

• Conductor configuration: single-core with two insulated conductors and an earth/return as indicated by the 1x2x2.50 designation
• Conductor size: 2.50 mm² (nominal cross-sectional area)
• Insulation type: LSZH (low smoke zero halogen)
• Shielding: overall shield for enhanced EMI protection
• Sheath colour: red for fire safety identification
• Length: 100 metres per drum
• Suitable for fixed, permanent installations inside buildings

How to use

Install the cable as part of the fixed wiring for fire detection and alarm systems, routing it from detectors to junction boxes or directly to the fire alarm control panel. Ensure correct polarity and continuity of the conductors and connect the shield to earth at a single point per circuit where required by the installation standard. Avoid mechanical damage and sharp bends when laying the cable; follow local electrical codes and the system manufacturer’s wiring diagrams. Use appropriate termination methods and test each circuit for insulation resistance and signal integrity before commissioning.

Usage recommendations

Store the cable in a dry, covered area until installation. Do not expose to oils, solvents or direct sunlight for prolonged periods. Use cable supports and fire-rated containment where required by building regulations, and perform periodic inspections to confirm mechanical integrity and connections remain secure.
