Which modification can help reduce false alarms on a burglar alarm system?

• A. Add time to the entry/exit delay
• B. Increase the siren volume
• C. Shorten the sensor response time
• D. Disable motion detectors

Answer: (A)

Giving more time for people to interact with the system before it triggers reduces false alarms. Extending the entry delay means a person can arm, enter, and disarm at their own pace without the system firing immediately. Extending the exit delay provides a longer window to exit after arming without the alarm going off. These delays help accommodate real-life timing, such as fumbling with a keypad or forgetting to disarm right away, which are common sources of false alarms. Increasing the siren volume doesn’t change why alarms trigger, and shortening sensor response time can actually make false alarms more likely by reacting too quickly to minor or accidental movements. Turning off motion detectors removes a major part of the security system, creating a gap that defeats the purpose of a burglar alarm. So, adding time to the entry/exit delay directly targets human timing issues that lead to false alarms, making it the best choice.
