Question 1

Guards can evaluate each situation as it arises and make reasoned responses. _________________________

Accepted Answer

Guards are trained to assess each situation and determine the appropriate response based on the circumstances. This requires critical thinking and decision-making skills.

Question 2

Vibration detectors measure rates of change in the ambient temperature of a room. _________________________

Accepted Answer

Thermal

Question 3

Videoconferencing is off-site computing that uses Internet connections, dial-up connections, connections over leased point-to-point links between offices, and other mechanisms. _________________________

Accepted Answer

TelecommutingMultiple Choice

Question 4

Grounding ensures that the returning flow of current is properly discharged to the ground. _________________________

Accepted Answer

Grounding provides a low impedance path for the returning flow of current to safely discharge to the ground, thereby preventing electrocution, fires, or damage to equipment.

Question 5

A gaseous system is designed to apply a liquid, usually water, to all areas in which a fire has been detected. _________________________

Accepted Answer

sprinkler

Question 6

Electronic monitoring includes __________ systems.
A) blocked video
B) local video 
C) open-circuit television
D) closed-circuit television

Accepted Answer

Electronic monitoring most commonly uses closed-circuit television (CCTV) systems to monitor and record activity. CCTV systems are often used in correctional settings and can be used for surveillance, safety, and security purposes. Blocked video and local video are not commonly used terms in relation to electronic monitoring, and open-circuit television is not a commonly used system in this context.

Question 7

Mechanical locks can accept a variety of inputs as keys, including magnetic strips on ID cards, radio signals from badges, personal identification numbers (PINs) typed into a keypad, or some combination of these to activate an electrically powered locking mechanism._________________________

Accepted Answer

Electromechanical

Question 8

__________ locks can be changed after they are put in service, allowing for combination or key changes without a locksmith and even allowing the owner to change to another access method (key or combination) to upgrade security.
A) Programmable
B) Manual 
C) Biometric
D) Electronic

Accepted Answer

Programmable locks allow for easy changes in combination or key without the need for a locksmith, making them a convenient choice for upgrading security. Biometric locks require specialized equipment and electronic locks may still require technician assistance, while manual locks do not have the option for easy key or combination changes.

Question 9

When the lock of a door fails and the door remains locked, it has a(n) fail-safe lock. _________________________

Accepted Answer

fail-secure

Question 10

Common forms of mechanical locks include electric strike locks, which (usually) require people to announce themselves before being "buzzed" through a locked door. _________________________

Accepted Answer

electronic

Question 11

In a double conversion offline UPS, the primary power source is the inverter, and the power feed from the utility is constantly recharging the battery, which in turn powers the output inverter. _________________________

Accepted Answer

online

Question 12

Smoke detection systems are perhaps the most common means of detecting a potentially dangerous fire, and they are required by building codes in most residential dwellings and commercial buildings. _________________________

Accepted Answer

Smoke detection systems are indeed required by building codes in most residential dwellings and commercial buildings.

Question 13

Class C fires are those fueled by combustible metals, such as magnesium, lithium, and sodium. _________________________

Accepted Answer

D

Question 14

Manual fire detection systems include human responses, such as calling the fire department and manually activated alarms. _________________________

Accepted Answer

Manual fire detection systems involve human intervention, which includes tasks such as reporting a fire to the fire department and activating alarms manually. So, the statement is true.

Question 15

Gaseous emission systems can be used in the suppression of fires. _________________________

Accepted Answer

Gaseous emission systems, such as clean agent fire suppression systems, can be used to extinguish fires by reducing the oxygen concentration in the air and/or interfering with the chemical chain reaction of the fire.

Question 16

A variation of the dry-pipe system is the pre-action system, which has a two-phase response to a fire. _________________________

Accepted Answer

In a pre-action system, the detection system must activate first, which causes water to fill the system's pipes, and then the sprinkler heads will release water when activated by heat. Therefore, it has a two-phase response to a fire.

Question 17

The most sophisticated locks are __________ locks.
A) manual
B) programmable 
C) electronic
D) biometric

Accepted Answer

Biometric locks use a person's unique biological characteristics such as fingerprints or iris scans to authenticate access, making them the most secure and sophisticated option among the given choices. Manual locks require physical keys, programmable locks use codes or cards for access, and electronic locks use electrical impulses to unlock, but all of them can be compromised with various techniques.

Question 18

__________ sensors work, for example, when a foot steps on a pressure-sensitive pad under a rug, or a window is opened.
A) Pressure
B) Contact and weight 
C) Motion
D) Movement

Accepted Answer

The answer of __________ sensors work, for example, when a...

Question 19

__________ occurs when an authorized person opens a door, and other people, who may or may not be authorized, also enter.
A) Crowdsurfing
B) Tailgating 
C) Freeloading
D) Hitchhiking

Accepted Answer

Tailgating occurs when an authorized person swipes their access card or opens a door, and someone else follows closely behind without using proper access credentials.

Question 20

Most guards have clear __________ that help them to act decisively in unfamiliar situations.
A) MACs
B) SOPs 
C) POSs
D) OPSs

Accepted Answer

SOPs (Standard Operating Procedures) are guidelines and instructions that are developed by organizations to help their employees perform routine operations. In the case of security guards, SOPs help them to act decisively in unfamiliar situations by providing them with clear procedures to follow. This helps to ensure that the guard responds appropriately and consistently, enhancing the safety and security of the premises they are protecting. MACs (Mandatory Access Controls), POSs (Point of Sale Systems), and OPSs (Operations Manuals) are not directly related to security guard procedures.
