If you're going to wholesale bulk screened security alarm cable made in China, welcome to get pricelist and free sample from our factory. All customized cables are with high quality and competitive price.
Screened security alarm cable is a shielded multi-conductor alarm cable with a metallic screen (aluminium foil, copper braid, or both) wrapped around the cores to protect low-voltage alarm signals from electromagnetic interference (EMI) and radio-frequency interference (RFI). It is the correct choice when cable runs pass near mains wiring, fluorescent lighting, motors, transformers, variable-speed drives or radio equipment. Available in 2 to 24 cores, shielded with foil, braid or foil-plus-braid, with PVC or LSZH jacket and CPR EN 50575 fire performance. Jiaxing Doublewin Cable Co., Ltd manufactures this cable in-house in Haiyan, Zhejiang, China and supplies it in bulk worldwide.

Why Clients Choose Our Security Alarm Cable
Reliable low-voltage signal cabling built for security alarm and access control systems, delivering stable performance and simple on-site installation.
Optimized Multi-Core Construction
Our multi-core security alarm cable packs multiple conductors within a single outer sheath. This consolidated design simplifies cable routing, reduces wiring clutter and reserves spare cores for future system expansion.
01
Robust Outer Sheath & EMI Protection
Premium sheath material offers strong abrasion and tear resistance. Screened versions include foil shielding to block electromagnetic interference, keeping alarm signals stable near motors and power cables.
02
Flexible Customisation for Project Needs
We support various core counts, conductor options (OFC / CCA) and sheath materials including PVC and LSZH. Tailored AWG sizes and sheath printing available for different commercial and residential security projects.
03
Rigorous Batch Quality Assurance
Every production batch is fully tested for conductor resistance, insulation integrity and screen continuity. Strict finished-cable inspection ensures uniform quality and reliable long-term operation for alarm systems.
04
Quality Control & Testing
Every reel is 100% tested before shipment. For screened cables we test shield continuity and resistance of the foil/braid screen and drain wire, insulation resistance between every pair of cores, and high-voltage withstand between all cores, the screen and the sheath. A sample of each batch is retained for full traceability. Third-party inspection (SGS, BV, TÜV) welcome.
Conductor Resistance
We verify conductor DC resistance to guarantee consistent signal transmission and avoid excessive voltage drop for long-distance alarm wiring.
Core-to-Core Insulation
Insulation resistance and high voltage withstand tests ensure no leakage or short-circuit risk between individual cores, even under continuous operation.
Batch Traceability
We reserve samples from every production batch, enabling full record tracking for quality audits, project acceptance and after-sales review.
Typical Applications
Screened security alarm cable adopts foil screening to block electromagnetic interference, maintaining stable low-voltage signal transmission. It is ideal for alarm sensors, PIR detectors and access control devices installed near motors, power cables and RF equipment.
Industrial Sites
Alarm and access control near motors, VSDs, conveyor systems and heavy machinery.
Hospitals & Clinics
Nurse call, fire alarm and security near MRI, X-ray and medical imaging equipment.
Commercial Kitchens Gas alarm and fire detection near microwave, induction and combi-oven equipment.
Data Centres & Comms Rooms Environmental monitoring and security alarm in high-RF environments.
Retail & Shopping Malls Security sensors, panic buttons and access control wiring across large retail zones.
