Which of the following is NOT considered a type of burglar alarm?

• A. Wireless alarm
• B. Fire alarm
• C. Hybrid system
• D. Wired system

Answer: (B)

A fire alarm is designed specifically to detect the presence of smoke, heat, or flames, primarily to prevent fire hazards and protect lives and property from fire damage. It serves a different purpose compared to burglar alarms, which are specifically designed to detect unauthorized entry into a property.

Burglar alarms are generally categorized into various types based on their technology, such as wireless, wired, and hybrid systems, which use a combination of both wired and wireless technologies. Thus, while all the other options can be classified as types of burglar alarms due to their role in security measures against theft, a fire alarm is associated with fire safety and not with burglar protection.
