Why Shielded Security Alarm Cable Matters
Alarm signals are low-voltage and easily disrupted by electromagnetic noise. In commercial and industrial buildings, unshielded alarm cable can pick up interference that causes false alarms, missed events or unreliable data on addressable loops. A shielded alarm cable wraps the signal cores in a metallic screen that diverts interference to ground, keeping the signal clean and the security system dependable.
EMI & RFI Protection
Metallic shield blocks interference from mains, motors, VSDs and radio equipment.
01
Fewer False Alarms
Clean signal integrity reduces nuisance alarms and missed events.
02
Copper Braid Option
Tinned copper braid (~85% coverage) for flex and RFI protection.
03
Aluminium Foil Option
100% coverage foil with drain wire for general EMI protection.
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
Shielded security alarm cable isolates low-voltage security signals from external electrical interference. It guarantees reliable signal transmission for burglar alarm sensors, PIR motion detectors and access control systems, especially for installations routed alongside power lines, rotating machinery and high-frequency electronic equipment.
Industrial Facilities
Security alarm and access control wiring in factories with variable speed drives, pumps and heavy machinery. The shielding prevents false alarms caused by strong electromagnetic noise.
Medical & Healthcare Premises
Burglary alarm, nurse call and access control wiring within hospitals and clinics. Works reliably near MRI, X-ray and other sensitive high-voltage medical equipment.
Commercial Utility Spaces
Gas detection and security alarm systems for commercial kitchens, plant rooms and boiler houses, where power circuits create heavy electrical interference.
Server & Communication Rooms
Security sensors and access control in data centres and comms cabinets. Shielding protects alarm signals from network hardware and power supply interference.
Retail & Public Buildings Motion sensors, panic buttons and door contact wiring in shopping centres, supermarkets and public venues, running alongside lighting and power cabling.
