Preventative maintenance (PM) is a service that offers early warning, brings peace of mind, and allows for revenue generation to security providers. Most Americans, since they began driving a car, know they need to change the oil in a vehicle on a regular basis. Most homeowners perform maintenance on their home on a yearly basis. Americans are used to the concept of PM. Failure to perform PM can be an expensive self-correcting injury; one not to be repeated without suffering.
The question is, why would homeowners not want to perform PM of security systems that are entrusted to work at all times? PM and annual testing are generally only offered when required, such as quarterly and for annual fire alarm testing required by an insurance provider. While there are no current PM requirements or annual audit requirements for alarm and/or security systems, this may change in the future.
