Installation Notes
This 22/2 riser security alarm bulk cable is specifically designed for vertical installations between floors in non-plenum spaces, such as riser shafts, elevator shafts, and vertical cable runs in walls. The CMR/CL3R rating ensures the cable meets fire safety requirements for these applications.
CMR/CL3R Riser Rating: The dual CMR/CL3R rating indicates:
- CMR (Communications Riser): Suitable for vertical runs per NEC Article 800
- CL3R (Class 3 Riser): Suitable for power-limited circuits per NEC Article 725
- FT4 Fire Test: Enhanced fire safety performance
- Meets fire safety standards for riser applications
- NOT suitable for plenum spaces (use CMP-rated cable)
- Appropriate for vertical cable runs between floors
Aluminum Foil Shielding: The aluminum foil shield provides important benefits:
- EMI/RFI protection: Blocks electromagnetic and radio frequency interference
- Signal integrity: Maintains clean signal transmission in noisy environments
