Which of the following is essential for ensuring the longevity of alarm system equipment?

Regular updates and maintenance are crucial for ensuring the longevity of alarm system equipment. This practice involves not only keeping the software and firmware of the alarm system current but also inspecting and servicing the hardware components. By conducting routine checks and maintenance, potential issues can be identified and addressed before they lead to system failure. This proactive approach helps maintain optimal performance and extends the lifespan of the equipment.

In contrast, while changing the battery annually is important for specific components within the system, it does not encompass the broader range of maintenance needed for overall system health. Simply using high-cost materials does not guarantee durability or reliability; effective maintenance is more vital. Additionally, minimizing usage could lead to degradation of the system's functionality; alarm systems are designed to be used regularly, and proper maintenance ensures they operate effectively when needed.
