A technician is investigating intermittent switch degradation. The issue only seems to occur when the building’s
roof air conditioning system runs. Which of the following would reduce the connectivity issues?
Adding a heat deflector
Redundant HVAC systems
Add a wireless network
EMI can cause circuit overload, spikes, or even electrical component failure. In the question it is mentioned that
switch degradation occurs when the building’s roof air-conditioning system is also running. All
electromechanical systems emanate EMI. Thus, you could alleviate the problem using EMI shielding.
