an alarm system in which radio signals are used to detect motion; the alarm is tripped when an intruder breaks the radio wave by moving into an rf field.
microwave detectors
perimeter control

Explanation:

• For Question 15: Territorial Reinforce involves increasing security by promoting informal environmental control. Radio - Frequency Fields are related to signal - based detection and Target Hardening is about making a target less vulnerable through physical or other means.
• For Question 16: Class C fires involve electrical equipment. Class A fires are for ordinary combustibles, Class B for flammable liquids and gases.
• For Question 17: Microwave detectors use radio signals to detect motion. When an intruder breaks the radio wave by entering an RF field, the alarm is triggered. Perimeter Control is a broader concept of securing an area's boundary.

Answer:
