Which of the following is a best practice when installing alarm systems?

Following manufacturer guidelines is a best practice when installing alarm systems because these guidelines are specifically designed to ensure the system operates safely and efficiently. Manufacturers conduct extensive testing and receive feedback on their products, which informs the recommended installation processes. Adhering to these guidelines can help prevent malfunctions, ensure optimal performance, and maintain the warranty on the equipment. Additionally, following these protocols shows compliance with industry standards and ensures that the system is set up according to the necessary regulatory requirements.

The other options do not represent best practices. Turning off notifications during setup might lead to missed alerts and configurations that could affect the system's security. Limiting the use of certified equipment undermines safety and reliability, as certified products usually meet specific safety and performance standards. Avoiding regular maintenance checks can lead to undetected issues and decreased effectiveness of the alarm system over time. Overall, following manufacturer guidelines is crucial for a successful and reliable installation of alarm systems.
