Are you a new or aspiring installation technician for the AV industry? If you’re going to pursue a career in installing AV systems, then you’re going to need to be knowledgeable about best practices for doing so. Effective installation is all about mastering the basics so that you have a good base to build up from when tasked with more complex AV design plans.

The three best practices outlined in this blog are essential to the skillset of a new technician. You must be able to prove that you have practical experience with these skills to be a contender in the competitive AV industry, especially since most technicians are freelance nowadays. Study these skills thoroughly and you’ll be able to hook multiple AV projects in no time!

1. Pulling Cable

Pulling cable goes along with your initial evaluation of a construction site, which is part of your pre-installation activities. When you first arrive at the site, check to see if the wiring system is continuous. If the system is found to be continuous you will have to use a vacuum to suck the pull string through the conduit or trunking to make it available for modifications. There will be instances where there is no conduit present on-site. You will be required to work together with another technician in these cases, to pull the cable through ceiling access to the system.

When pushing and pulling the cable through the ceiling, you’ll require a push rod that you can attach the pull string to or pull by fishtape. Once the pull string is brought through on the other side of system it can be attached to cable head by looping the string around it, making sure the loop knots are in between the bundle of cables before you tape them together.

Once you’ve secured the front of the pull string is at the top of the cable head, work together with another technician to pull and guide the cables through the system. Make sure that you are grabbing the string and cables with the side of your hand to avoid potential injuries.

2. Terminating Cable

Terminating cable is the act of preparing cables for one of several termination methods, choosing the correct connector for termination and testing wiring systems for efficacy. Termination prevents signals transmitted through the cables from reflecting off the transmission line, resulting in imprecise or irregular digital signal levels.

Proper cable termination ensures that AV systems, which digitally transform at a rapid rate, aren’t operated ineffectively. You must gather appropriate tools and materials to aid your chosen method of termination. Some examples of termination methods are: screw terminal and crimping, compression or linear compression, insulation displacement, soldering, and fiber optic.

Termination is a complex subject and cannot be covered at depth here, but there are online installation credentials offered by AV experts that can give you practical experience.

3. Mounting Equipment

Mounting equipment properly is all about ensuring that whatever displays you’re mounting on the walls of your construction site are level. To do this you need a measuring tape, some construction tape to make placement markings on the back of the display for reference, and a leveling device. This installation activity, like pulling cable, is also more efficient if you have an extra pair of eyes to confirm that the equipment is mounted correctly.

You should start by measuring the attached mount on the back of the display. Make any adjustments using measuring tape, construction tape and pencil markings so that the permanent mounting location is as accurate as possible. Hold up the mount to the wall you’ll be attaching it to and test to see if it blocks any outlets. Finally, you’ll need to check the alignment of the display and pilot the hole locations and complete the mounting.

Master these three practices and you’ll be an attractive candidate in the AV industry in no time.
