Logico PLC4503 18/4 Security Wire 500ft White

18/4 Security Wire 500 ft

Logico PLC4503 is an 18 AWG four-conductor security wire supplied in a 500-foot pull box. The stranded copper-clad aluminium conductors are enclosed in a white PVC jacket rated CL2 for power-limited circuits. It is designed for low-voltage alarm and control wiring in residential and commercial installations.

Installers wiring sensors.

This cable suits installers who need a single reel for door contacts, window sensors, keypads and motion detectors connected to a central alarm panel. The CL2 rating allows in-wall runs without conduit in most jurisdictions. Buyers requiring shielded conductors, plenum-rated jackets or solid copper cores should select a different cable type.

18 AWG four-conductor CL2 rating

The decisive specification is the 18 AWG four-conductor construction with a CL2 power-limited rating. This combination determines voltage-drop limits, code compliance for in-wall installation and compatibility with standard alarm-panel terminals. Verify that your panel and local code accept 18 AWG CL2 cable before purchase.
