Product Information
Full details
This PRO POWER 4 Core Screened Alarm & Signal Cable is designed for professionals and DIY enthusiasts needing reliable signal transmission in alarm and security systems. Its key benefit is enhanced signal integrity due to its screened construction, ensuring fewer interference issues. A potential caveat for some users might be the CCA (Copper Clad Aluminium) conductors, which differ from pure copper in conductivity and flexibility. Key features include a 4-core design, aluminium screening, 0.22mm CSA, 100m reel length, and compliance with CPR Cat Eca standards.

FAQs
What is CCA and why is it used?
CCA stands for Copper Clad Aluminium. It is an electrical conductor material that consists of a core of aluminium alloy surrounded by a thin layer of copper. It is used to reduce costs compared to pure copper while still offering good conductivity for signal applications.
What does 'Screened' mean in this cable?
Screened means the cable has an outer layer of shielding, in this case, an aluminium screen. This shield helps to protect the internal conductors from external electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring a cleaner signal.
What are the benefits of the aluminium screen?
The aluminium screen reduces noise and interference picked up by the cable, which is crucial for reliable data transmission in alarm and signal systems. It helps prevent false triggers or corrupted data.
Is this cable suitable for mains power?
No, this cable is specifically designed for alarm and signal applications, which are low-voltage. It is not rated or intended for use with mains electricity (e.g., 110V/230V).
What does CPR - Cat Eca mean?
CPR stands for Construction Products Regulation. Cat Eca is a classification under this regulation indicating the cable's reaction to fire performance. Category Eca is a basic level of fire performance for cables used in buildings.
Can I use this cable for longer distances?
While the screening helps maintain signal quality, the 0.22mm CCA conductors may experience voltage drop over very long distances. For critical applications or runs exceeding recommended lengths for 0.22mm wire, consult your equipment's specifications or consider a cable with a larger conductor size.
Troubleshooting
Intermittent signal loss or noise
Ensure the aluminium screen is correctly terminated at one end to act as a ground. Check all connections for looseness or corrosion. Verify that the cable is not routed too close to high-power electrical cables or sources of electromagnetic interference.
Cable is difficult to work with or kinks easily
This may be due to the CCA construction. Allow the cable to relax from the reel for a while before installation. Avoid forcing sharp bends; instead, use gentle curves to route the cable.
Low voltage at the end of a long run
The 0.22mm CSA conductors and CCA material may cause a noticeable voltage drop over very long distances, especially if carrying more than a minimal signal current. Consider using a thicker gauge cable or a different conductor material (like pure copper) if voltage drop is critical for your application.
Pros and Cons
Pros
- Enhanced signal integrity due to aluminium screening.
- Convenient 100m reel for ease of installation and management.
- CPR Cat Eca certification provides assurance of safety standards.
- Suitable for a variety of alarm and signal applications.
Cons
- CCA conductors are less conductive and flexible than pure copper.
- May not be suitable for high-power or long-distance applications requiring maximum conductivity.
- Screening adds a slight increase in cable diameter compared to unscreened variants.
Setup, Compatibility & Care
Setup: This cable is designed for straightforward termination using standard alarm and signal connectors. Ensure conductors are stripped cleanly and securely connected to their respective terminals. The aluminium screen should be properly terminated at one end, typically at the control panel, to create an effective ground plane and shield against interference. Use appropriate cable ties or clips to secure the cable neatly during installation, avoiding sharp bends or kinks.
Compatibility: Compatible with most standard alarm control panels, CCTV systems, access control devices, and other low-voltage signal transmission equipment. Ensure the conductor size (0.22mm CSA) and CCA construction meet the specific requirements of your connected equipment, particularly regarding voltage drop and signal loss over longer distances.
Care: Store the cable on its reel in a dry environment, away from direct sunlight and extreme temperatures, to preserve the integrity of the insulation and the screen. Avoid exposing the cable to harsh chemicals or abrasive materials. During installation, protect the cable from physical damage.
