Cable Delivery and Installation
Cable is usually delivered first for the installation by a licensed electrician.
All cabling must be installed in accordance with applicable sections of the national electrical code and in accordance with AHJ requirements. Some AHJs require the use of EMT conduit and others require cable to be labeled every 4 feet.
We use a non-radiating, fully shielded type of cable that can be run against other metal structures and alongside other wiring. However, all cable runs must be individually supported at least every 4′ using standard wiring mounts such as mini-clips or other clamps that do not crush the cable. No special standoffs or procedures are needed.
Please pay special attention to the cable integrity – the air dielectric cable kinks very easily. It must not be bent into a kink or crushed in any way. Any deformation of the outside shield will result in degraded performance (increased insertion loss).
The electrician will at the same time install an 8-Conductor cable for the dedicated annunciator panel as well as the fire alarm SLC loop.
Antenna Installation
BDA technicians terminate coaxial cables, install antennas and signal coupler, dividers and make all necessary connections.
Antennas may be mounted vertically for slightly better horizontal coverage area or horizontally for improved vertical floor penetration.
Please make sure that the active part of the antenna (fiberglass) is away from metal as much as possible. The antenna should be at least 14″ away from any metal such as other cables, HVAC, ducts, pipes, I-beams, drop-ceiling frame support, conduits etc.
If the antenna is going to be installed inside a closed ceiling, it is best to use a nonmetallic service access hatch. Please ensure building code fire survivability compliance as required.
