a limited - use alarm system set to accept a predetermined radiation level and trigger an alarm if a person enters the area.\ninfrared radiation detection\nlocal alarms\nmicrowave detectors\nquestion 62 (1 point)\na perimeter control system, usually buried in the ground, which registers pressure; its use is limited within the industry and is generally only for highly specialized protection needs.\nseismic detector\nremote alarm\nradio frequency fields
Answer
Brief Explanations:
- For the first question, infrared radiation detection systems can detect changes in infrared radiation when a person enters an area and can be set to trigger an alarm based on a predetermined level. Local alarms are just a general type of alarm and not specific to radiation - based detection. Microwave detectors work on the principle of microwave reflection and not on detecting a specific radiation level for the described scenario.
- For the second question, seismic detectors are often buried in the ground and can register pressure changes caused by movement in the vicinity. Remote alarms are for alerting from a distance and not related to ground - based pressure registration. Radio frequency fields are not used for registering ground - based pressure for perimeter control in the described context.
Answer:
Question 61: Infrared radiation detection Question 62: Seismic detector
