Description
The SOUTHWIRE/COLEMAN CABLE 453 is a 50-foot spool of 24/2 AWG Type CL2 low-voltage bell wire designed for residential and light commercial signal and control wiring. Conductors are soft annealed solid copper, which provides reliable continuity in low-current applications. The thermoplastic insulation meets CL2 classification requirements, making this cable appropriate for in-wall and concealed routing where a Class 2 low-voltage rating is required. Electricians and alarm technicians reach for this wire when running dedicated signal circuits for doorbells, intercoms, burglar alarm sensors, and thermostat control wiring. The spool format keeps the wire manageable during installation and reduces tangling on the job.
This bell wire is suited for residential and light commercial signal wiring applications including thermostat control circuits, door chime and doorbell systems, intercom wiring, and burglar alarm sensor runs. Its solid copper conductor construction supports stable resistance over the length of the run, which matters in low-voltage signal circuits where voltage drop can affect device operation. The 50-foot length covers most single-zone thermostat or doorbell rough-in runs without splicing. It ships in a package quantity of 10 spools, making it practical to stock for service vehicles or job-site supply.
Key Features
- 24/2 AWG soft annealed solid copper conductors for reliable low-current signal performance
- Type CL2 rated thermoplastic insulation suitable for in-wall concealed wiring installations
- 50-foot spool length covers typical single-zone thermostat and doorbell rough-in runs
- Suitable for thermostat controls, burglar alarms, intercoms, and doorbell circuits
- Spooled format for tangle-free dispensing during installation
- Sold in a package quantity of 10 spools for stocking and fleet supply
Compatibility
Designed for low-voltage signal and control wiring applications including thermostat controls, doorbell systems, intercom systems, and burglar alarm sensor circuits where CL2-rated 24 AWG 2-conductor cable is specified.
Installation Notes
Installation of CL2 low-voltage wiring should follow NEC Article 725 requirements for Class 2 circuits. Power down any connected control system or alarm panel before connecting or terminating wires. Use a dedicated low-voltage staple or cable clip rated for signal wire when securing runs to framing avoid stapling through the jacket. Licensed electricians or alarm technicians should perform in-wall installations in jurisdictions that require it.
