Q

In a ___, both sensors have to be activated for the alarm to trip, which reduced the percentage of nuisance alarms,
making these sensors a great choice for reliability.

A

Dual Technology Sensor

17
Q

The drawback of a Dual Technology Sensor is that it has a higher ___ than an Individual Technology sensor.

A

Probability of Detection (PD)

18
Q

___ use Doppler shift technology. They penetrate most areas and materials and nuisance alarms can be generated from adjacent areas.

A

Microwave Sensors

19
Q

To limit coverage of Microwave sensors, use a ___.

A

Variable Range Cut-off circuit

20
Q

Because of the higher resolution of the ___, the greater the accuracy of and performance of the ___, they typically operate better for interior applications

A

VMD

21
Q

Interior sensors may be characterized by three main applications.

A
  1. Boundary Penetration Sensors
  2. Interior Motion Sensors
  3. Proximity sensors
22
Q

In ___ applications, a dual technology sensor should not be used in place of two separately mounted sensors due to the reduced PD

A

High Security

23
Q

___ are susceptible to air movement and should not be installed near stairwells or hallways, but rather into rooms or areas where only infrequent access occurs

A

Ultrasonic Sensors

24
Q

An ___ should have the ability to perform a self-test on a regular basis.

A

Intrusion Detection System (IDS)

25
Q

An ___ system is the part of the electronic security system that transports alarm signals and assessment information to a central point and presents the information to a human operator. It collects data and enables the operator to enter commands to control the system.

A

Alarm Communications & Display (AC&D

26
Q

AC&D displays are typically located ___ and should not require much head or eye movement form the operators line of sight for the primary interface area (30 degree cone).

A

In the center of the console

27
Q

What does AC&D stand for?

A

Alarm Communications & Display

28
Q

A ___ is often referred to as a “metal detector” but has many differences to the modern-day metal detectors, and should not be used for contraband detection.

A

Magnetometer

29
Q

___ are designed to be in close proximity to small amounts of steel and other metals in the surrounding areas; however, a ___ should not be installed very close or against a steel support beam.

A

Metal detectors

30
Q

___ detectors may not penetrate heavy metals (like a metal shipping container or some metal compartments on vehicles); however, a high energy or multiple energy x-ray can be used for screening.

A

Conventional x-ray

31
Q

What does QR stand for?

A

Quadrupole Resonance

32
Q

___ technology uses low radio waves to direct the presence of nitrogen-rich materials, which are found in bulk explosives. ___ technology is compact and has a low cost (about 100,000)

A

Quadrupole Resonance (QR)

33
Q

___ uses a spectroscopic technique. It uses laser interrogation, which is followed by light analysis. It is not stave for package searches.

A

Ramen Analysis

34
Q

What does MS stand for?

A

Mass Spectrometry

35
Q

___ uses magnetic and electrical fields to process ions and determine the mass-to-charge ratio.

A

Mass Spectrometry

36
Q

___ has applications in law enforcement and military for both drugs and explosives and is a good choice when mobility is required. The acquisition costs for the canine are low, but the maintenance, training and handler labor costs are very expensive over time.

A

Canine Olfaction
