## Description

Syston Cable Technology 18/3 Low Voltage Security Sound Alarm Cable 500 ft 18 AWG 3 Conductors Stranded Copper Shielded Plenum Rated CMP CL3P FPLP FT6 UV Resistant: desertcart.com: Tools & Home Improvement

## Features

- Multiple Applications: Wiring Fire Alarm, Security Burglar Alarm, Public Address Systems, Intercoms, Telephone Stations, Communications, Instrumentation, Access Control, Nurse Call, Security and Other Low Voltage Circuits that are Power-Limited Applications.
- Pure Copper Conductors: Our control cable is built with stranded bare copper conductors, providing maximum conductivity and reliability to ensure that your systems run smoothly.
- Shielding Performance: The aluminum foil shielding layer prevents electromagnetic interference (EMI) from affecting the signal transmission within the cable. By blocking external interference, the aluminum foil ensures that the signal remains clear and free from distortion, which is especially important in high-speed data transmission and sensitive communication applications.
- CMP (Plenum-Rated): Our cable is designed with your safety in mind. It has the flame retardant grade of CMP/CL3P/FT6 (Plenum Rated) and is the highest flame retardant cable. This cable suited to go in the plenum spaces of buildings such as ceilings and enclosures, that are also used by the building for air distribution systems to transport air. CMP is higher than commercial grade cable CMR and civil grade cable CM.
- 300V Low-Voltage Circuit Cable (CL3 Rated): 300V rating ensures superior insulation and a high safety margin for low-voltage use, making it ideal for thermostats, security systems, and audio/visual installations while complying with Class 3 (100VA) power-limited standards.

## Questions & Answers

**Q: What is this control cable commonly used for?**
A: This low-voltage control cable is designed for a wide range of applications, including security and alarm systems, LED dimmer control, HVAC controls, burglar station, intercoms, gate operators, and other low-voltage signaling and control equipment.

**Q: Is this cable made with pure copper conductors or CCA?**
A: This cable is manufactured with bare copper conductors, not copper-clad aluminum (CCA). Pure copper provides better conductivity, lower resistance, improved signal integrity, and greater long-term reliability for control and communication circuits.

**Q: Can this cable be installed in walls, ceilings, or commercial buildings?**
A: Yes. Depending on the version selected, this cable is available in CMR (Riser) or CMP (Plenum) ratings. CMR is suitable for riser installations, while CMP is approved for plenum spaces. Always follow local electrical codes.

**Q: Can this cable be used outdoors or for direct burial?**
A: This cable can be used indoors or in protected outdoor locations. It is not rated for direct burial and should be installed in conduit or other suitable protection when exposed to outdoor conditions.
