VERTICAL CABLE 211-186ST/S/GY – 18/6 SHIELDED STRANDED SECURITY CABLE
The 211-186ST/S/GY is a shielded 18 AWG, 6-conductor security cable made for indoor alarm, access control, and intercom wiring. Six color-coded, stranded copper conductors sit under an aluminum foil shield with a drain wire, keeping signal runs clean around electrical noise. Rated CM/CL2 and supplied on a 1,000 ft spool with sequential length markings, this security cable is built for fast, predictable pulls on commercial and residential security jobs.
KEY FEATURES
Here’s what makes the 211-186ST/S/GY a dependable security cable:
- 18 AWG, 6-Conductor Design: Six stranded bare copper conductors handle power and signal in a single jacket.
- Foil Shielding with Drain Wire: Aluminum foil and a tinned copper drain wire help block EMI/RFI interference on sensitive alarm and access control circuits.
- CM/CL2 Rated: Dual-marked for communications and Class 2 power-limited circuits under the NEC.
- Color-Coded Conductors: Red, black, white, green, brown, and blue insulation makes termination and troubleshooting easier.
- Rip Cord: Makes it simple to strip the jacket without nicking the conductors.
- Sequential Length Markings: Printed on the jacket so you can measure and cut runs quickly.
- 300 V RMS Voltage Rating: Well above the 150 V minimum for Class 2 cable.
- 75°C Temperature Rating: Suited to typical indoor security installations.
- Sunlight-Resistant Jacket Marking: The gray PVC jacket carries a “SUN RES” marking.
- ETL-Listed and RoHS-Compliant: Independently listed and built to environmental standards.
- 1,000 ft Wooden Spool: Bulk packaging for larger jobs.
APPLICATIONS
The 211-186ST/S/GY is designed for indoor security and low-voltage signaling:
- Indoor Remote Control of Security Systems: Connect panels, keypads, and remote devices over shielded runs.
- Access Control: Wire door controllers, card readers, proximity sensors, and keypads.
- Intercom Systems: Carry audio and control signals between stations.
- Sound and Audio Systems: Run low-voltage audio and control wiring indoors.
- Smoke Detectors: Wire detector circuits on security and alarm panels, subject to local fire code requirements.
- General Indoor Applications: Suitable for non-plenum, non-riser indoor runs.
WHY CHOOSE THE 211-186ST/S/GY SECURITY CABLE?
Professionals choose the 211-186ST/S/GY for its shielded construction, six-conductor flexibility, and installer-friendly details. Here are 5 reasons to specify it for your next project:
- Shielded Signal Protection: Foil and drain wire help keep alarm and access control signals clean.
- Six Conductors, One Pull: Power and signal travel together, so you need fewer cable runs and can install faster.
- Easy Termination: Color-coded conductors and a rip cord speed up prep work.
- Faster Planning: Sequential length markings remove the guesswork from measuring and cutting.
- Listed and Compliant: CM/CL2 rating, ETL listing, and RoHS compliance support code-conscious installations.
GETTING IT INSTALLED
Once the 211-186ST/S/GY is on the truck, here’s what to keep in mind:
- Keep it indoors and out of plenums and risers. CM/CL2 is a general-purpose rating. For plenum spaces or vertical riser shafts, you’ll need plenum- or riser-rated cable instead.
- Use a listed Class 2 power supply. Class 2 circuits depend on a listed Class 2 transformer or power supply to stay power-limited, so check that before you energize.
- Keep it separated from power wiring. Class 2 circuits generally need to stay separate from Class 1 and power conductors in raceways and boxes, so plan your pathways accordingly.
- Ground the shield the way the equipment maker says. Terminate the foil and drain wire per the panel manufacturer’s instructions to get the full benefit of the shielding.
- Check fire code before wiring smoke detectors. Fire alarm circuits fall under NEC Article 760 and NFPA 72, and some jurisdictions require fire alarm-marked cable. Confirm with your local authority before pulling.
