Which of the following is NOT one of the three points of burglar alarms?

• A. Detect the entry
• B. Signal their presence
• C. Initiate certain procedures intended to prevent or minimize the loss
• D. Monitor environmental conditions

Answer: (D)

The fundamental purpose of a burglar alarm is to act in three steps: first, detect the intrusion or entry, second, signal that detection to deter the intruder and alert occupants or nearby people, and third, initiate procedures that prevent or minimize loss—such as notifying a monitoring service or authorities, sounding alarms, and triggering automatic responses. Monitoring environmental conditions isn’t part of these core actions; it relates more to fire, gas, or environmental safety systems rather than the basic intrusion-detection-and-response sequence. So the option describing monitoring environmental conditions doesn’t fit as one of the three points.
