Question 21

alternatively, may have a dial that rotates slotted discs until the slots on multiple disks are aligned, and then retracts a securing bolt (as in combination and safe locks).

Answer 21

Mechanical Lock

Question 22

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

Question 26

are commonplace and well understood. If you have the key (or combination) you can open the lock. These locks are often preset by the manufacturer and therefore unchangeable

Answer 26

Manual Locks

Question 27

can be integrated into alarm systems and combined with other building management systems. Also, these locks can be integrated with sensors to create various combinations of locking behavior. One such combination is a system that coordinates the use of fire alarms and locks to improve safety during alarm conditions (i.e., fires).

Answer 27

Electronic locks

Question 28

A common enhancement for locks in high security areas

Answer 28

Answer 29

Mantrap

Question 30

To gain access to the facility, area, or room, a when a person, requests access via some form of electronic or biometric lock and key, and if confirmed, exits the mantrap into the facility. Otherwise the person cannot leave the mantrap until a security official overrides the enclosure’s automatic locks.

Answer 30

Mantrap

Question 31

can be used to record events within a specific area that guards and dogs might miss, or in areas where other types of physical controls are not practical.
