Product Information
Full details
This 25-meter, 8-way/4-pair white alarm cable from Loops is designed for low-voltage security and CCTV installations. It offers a reliable connection for PIR sensors, door/window contacts, and control panel linking, featuring tinned copper clad aluminum cores for durability. A key consideration is to account for voltage drop over long distances, especially at higher currents, which may require techniques like doubling up cores.

FAQs
What is the maximum voltage this cable can handle?
This cable is rated for a maximum working voltage of 50V RMS. It is designed for low-voltage applications only.
Can I use this cable for power transmission?
Yes, but only for low-power devices due to its 1A current rating. For longer runs or higher current needs, voltage drop must be considered.
What does 'tinned copper clad aluminum' mean?
It means the core is made of aluminum that is coated (tinned) with copper. This offers good conductivity and corrosion resistance, often at a lower cost than pure copper.
How do I connect the individual cores?
You will need to carefully strip the insulation from the ends of the specific cores you are using and connect them to the appropriate terminals on your security system components.
What are the core colors included?
The cable includes Yellow/Green, White, Black, Red, Blue, Orange, and Brown cores.
What is the conductor area per core?
The conductor area (CSA) per core is 0.22mm².
Is this cable suitable for outdoor use?
The PVC outer insulation provides some protection, but it's best to protect the cable from direct exposure to harsh weather conditions and UV light for long-term reliability.
Troubleshooting
No signal from connected device
Check all connections at both ends for security. Verify the correct cores are used for signal transmission. Measure continuity of the signal wire using a multimeter.
Intermittent device failure
Inspect the cable for any signs of physical damage, kinks, or sharp bends. Ensure connections are clean and tight. Test for voltage drop if the run is long.
Short circuit detected
Carefully inspect the cable run for any points where insulation may have been compromised, causing wires to touch. Ensure stripped ends do not overlap or touch inappropriately.
Low voltage at the device
Calculate the expected voltage drop for the cable length and current draw. If significant, consider using thicker gauge cable or doubling up cores for the run.
Pros and Cons
Pros
- Suitable for a wide range of low-voltage security applications.
- Color-coded cores simplify installation and troubleshooting.
- Tinned copper clad aluminum offers good conductivity and corrosion resistance.
- Flexible yet durable PVC insulation protects the conductors.
- Standard 25-meter length is practical for many common installations.
Cons
- Current rating is limited to 1A, suitable only for low-power devices.
- Potential for significant voltage drop over long distances must be managed.
- Tinned copper clad aluminum may not offer the same conductivity as pure copper for high-demand circuits.
- Not suitable for mains voltage applications.
Setup, Compatibility & Care
Setup:
- Identify the required number of cores for your connection (e.g., power, signal, ground).
- Carefully strip the outer PVC jacket to expose the inner cores.
- Strip a small amount of insulation from the end of each conductor you intend to use.
- Connect the cores to the appropriate terminals on your devices (e.g., control panel, sensors).
- Ensure all connections are secure and insulated.
Compatibility:
- Suitable for all low-voltage alarm systems and CCTV equipment operating at 50V RMS or less.
- Compatible with standard security system components like PIR sensors, magnetic contacts, sirens, and control panels.
- Ensure the 1A current rating is sufficient for the connected devices.
Care:
- Store the cable in a cool, dry place away from direct sunlight.
- Avoid sharp bends or kinking the cable during installation to prevent internal damage.
- Protect the cable from physical damage, extreme temperatures, and moisture in its installed environment.
