Installing a wireless outdoor intercom on a pole is a practical solution for enhancing communication in various settings. Here’s a step-by-step guide to help you plan and execute the installation, using easily accessible materials from stores like The Home Depot.
Materials Required:
- 8-foot, 2 3/8" Galvanized Fence Pole: The main support for the intercom and antenna.
- 2" Electrical Conduit (10-foot piece): To reinforce the pole and secure it to the ground.
- Pre-mixed Fast Setting Concrete: For stabilizing the pole in the ground.
- Bolts or Sheet Metal Screws: To secure the pole to the conduit.
- Decorative End Cap (Optional): To cover the top of the pole, giving it a finished look and preventing rain from entering.
- Cable Bushings: To protect cables from rubbing against sharp edges of drilled holes.
- Antenna Extension Cable (3 feet): If needed, to position the antenna optimally.
Step 1: Pole Selection and Preparation
The main structure of your intercom system will be an 8-foot, 2 3/8" galvanized fence pole. For a polished look and to protect the inside of the pole from rain, you can add a decorative end cap to the top.
Since the total height of the installation should be around 8 feet, you'll need a way to secure the pole without reducing its height. This can be achieved by using a 2" piece of electrical conduit. A 10-foot conduit can be cut in half, giving you two 5-foot sections.
Step 2: Ground Installation
Dig a 2-foot deep hole for the foundation of the pole. Insert one of the 5-foot conduit pieces into the hole. Pour fast-setting concrete mix into the hole around the conduit, adding water as per the product’s instructions. Once the concrete hardens, slide the galvanized fence pole over the exposed 3-foot section of conduit.
To secure the fence pole to the conduit, use bolts or sheet metal screws. This ensures the structure remains stable over time.
Step 3: Mounting for ADA Compliance
When installing the intercom callbox, ensure the Talk button is positioned at 48 inches above the ground to comply with ADA (Americans with Disabilities Act) standards. This height allows individuals in wheelchairs to access the intercom comfortably.
Step 4: Drilling Holes for Cables and Equipment
You will need to drill holes in the fence pole to run your cables and mount the necessary equipment. It’s essential to use bushings to protect the cables from being damaged by the sharp edges of the drilled holes. If you’re installing a Multi-Mile callbox, it comes with pre-installed cable bushings, making the process simpler.
Step 5: Antenna Installation
To ensure optimal performance, mount the antenna as high as possible on the pole. This minimizes signal interference caused by the metal pole itself and extends the communication range. You may need an antenna cable extension to add about 3 extra feet of cable, which can be sourced from IntercomsOnline.com.
To route the cables through the pole, use a fish tape or stiff wire to guide them. Secure the antenna to the pole using #12 x 3/4" hex head sheet metal screws, making sure it’s positioned for the best signal reception.
Final Touches
Once the pole is securely mounted and all components are installed, check that the intercom system is functioning correctly and the antenna is positioned for maximum range. Adding a decorative end cap can provide a neat, finished look to your installation, while also protecting the inside of the pole from weather-related damage.
