18/4 Shielded Cable for Security Systems

The Logico PLC4508 is an 18 AWG four-conductor shielded cable built for low-voltage security installations. Stranded bare copper conductors provide flexibility for routing through walls and ceilings. The CMR and CL3R ratings allow in-wall and riser use in residential and commercial projects. Supplied in a 1000 foot pull box for continuous runs.

CMR and CL3R rated for sustained in-wall use

The PVC jacket and shielding meet fire-safety requirements for vertical riser and general in-wall placement. Shielding helps reject interference from nearby electrical circuits during long-term operation. Stranded construction withstands repeated pulling and bending without conductor fatigue. The 1000 foot length reduces splice points on large installations.

18 AWG gauge sets voltage-drop limits

The 18 gauge conductors determine the maximum run length for a given current load before voltage drop affects device operation. Installers must calculate distance against sensor and keypad power requirements. The four conductors carry power and signal pairs for typical alarm devices. The white jacket identifies circuits in multi-cable bundles.

Questions about this item

How much heat or power does this 18 AWG shielded cable generate when running continuously?

As a passive low-voltage wire, it produces no measurable heat or power draw; the only losses are the small resistive drop across the 18 AWG conductors over the 1000 ft length.

What connectors or termination tools must I already own to use this 4-conductor shielded cable?

You will need standard low-voltage connectors — screw terminals, crimp pins or IDC blocks — plus a wire stripper and crimp tool sized for 18 AWG stranded copper.

Will the 18/4 shielded construction work alongside older unshielded alarm wire already in the walls?

Yes, the CMR/CL3R jacket and foil shield are electrically compatible with legacy unshielded runs; just maintain separate shield grounding at the panel to avoid ground loops.
