What element could reduce the effectiveness of an alarm system?

Failure to properly arm the system significantly reduces the effectiveness of an alarm system because an alarm’s primary function is to detect unauthorized access or breaches when it is active. If the system is not armed, it will not trigger alerts or notifications in the event of an intrusion. This means that the entire purpose of the alarm is compromised, leaving the premises vulnerable and unprotected.

In contrast, keeping software regularly updated enhances security by patching vulnerabilities, while placing alarms in high-traffic areas can actually deter intruders. Additionally, utilizing multiple types of alarms can bolster security by providing varied detection methods, thus enhancing the overall effectiveness of the alarm system.
