£44.16 (inc VAT: £52.99)
Summary
The Securi-Flex Alarm Type 1 Copper LSZH Screened cable represents the ultimate specification for alarm installations in the most demanding and critical environments. This 8 core screened alarm cable combines pure tinned copper conductors with advanced LSZH (Low Smoke Zero Halogen) construction and comprehensive screening, making it the premium choice for high-security installations, data centres, hospitals, and environments where both fire safety and signal integrity are absolutely critical.
Building upon the superior electrical performance of Type 1 pure copper conductors, this cable adds comprehensive screening with a dedicated tinned copper drain wire. The screening provides exceptional protection against electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring reliable alarm system operation even in electrically noisy environments filled with electronic equipment, fluorescent lighting, motors, and other sources of electrical interference. This makes it essential for installations in industrial facilities, IT environments, and any location where signal integrity cannot be compromised.
The cable achieves an outstanding Dca-s1-a1-d1 CPR classification – featuring enhanced s1 smoke performance compared to standard Dca-s2 rated cables. Combined with complete LSZH insulation and jacketing throughout, this cable produces minimal smoke and absolutely zero halogen gases in the event of fire, providing maximum safety for building occupants and protecting sensitive electronic equipment from corrosive fumes. The white LSZH sheath offers a clean, professional appearance for visible installations in premium commercial, public, and critical infrastructure environments where fire safety, signal integrity, and system reliability are paramount. With lower DC resistance (100Ω/km), extended temperature range (-40°C to 70°C), and professional-grade construction, this cable represents the pinnacle of alarm cable technology.

FAQs
What makes this the ultimate alarm cable specification?
This cable combines three premium features: Type 1 pure copper conductors for maximum electrical performance, comprehensive screening with drain wire for superior EMI/RFI protection, and full LSZH construction with Dca-s1-a1-d1 fire rating. It offers the lowest resistance (100Ω/km), best signal integrity, highest fire safety performance, and maximum protection against electrical interference – making it the ultimate choice for critical installations where reliability cannot be compromised.
What is the difference between Dca-s1 and Dca-s2 ratings?
The s1 smoke rating indicates even lower smoke production than s2 in the event of fire. While both are excellent classifications, s1 represents the highest smoke performance level, producing minimal smoke that provides maximum visibility for evacuation and firefighting operations. This enhanced smoke performance is particularly important in underground installations, enclosed spaces, and critical facilities where smoke obscuration could be life-threatening.
When should I specify screened cable over unscreened?
Specify screened cable in electrically noisy environments such as data centres, server rooms, industrial facilities, hospitals with extensive electronic equipment, or anywhere fluorescent lighting, motors, variable speed drives, or other sources of EMI/RFI are present. The screening prevents electrical interference from causing false alarms or signal degradation. In critical security installations, screening also provides a degree of protection against signal interception or tampering.
What is the drain wire and how is it used?
The tinned copper drain wire runs alongside the cores and provides an easy termination point for the cable screen. Instead of trying to terminate the delicate screening braid directly, installers connect the drain wire to earth/ground, which electrically connects the entire screen. This simplifies installation while ensuring the screening is properly terminated for maximum EMI/RFI protection. The drain wire must be connected at one end only to prevent ground loops.
How does this compare to the Type 3 TCCA screened LSF version?
This Type 1 LSZH screened cable offers several advantages: pure copper conductors (vs TCCA) provide 35% lower resistance for better signal integrity, LSZH construction (vs LSF) produces zero halogen gases rather than just low smoke and fume, and Dca-s1 rating (vs Eca) offers superior fire performance with lower smoke production. While more expensive, this cable is essential for critical installations where maximum performance, safety, and reliability justify the investment.
Is this cable worth the premium cost?
For critical installations in data centres, hospitals, transport infrastructure, industrial facilities, or any environment where alarm system reliability is mission-critical, the answer is absolutely yes. The combination of pure copper conductors, comprehensive screening, and superior LSZH fire performance provides unmatched reliability, safety, and longevity. The lower resistance enables longer cable runs, the screening prevents costly false alarms, and the enhanced fire safety protects lives and valuable equipment. In high-specification projects, this cable delivers exceptional value through superior performance and peace of mind.
