Question 1

Switches which are activated by pressure are called photoelectric devices.

Accepted Answer

Switches which are activated by pressure are called pressure switches, not photoelectric devices. Photoelectric devices use light to activate or sense a switch.

Question 2

The basic types of alarm systems include all of the following except:&#10;A) intrusion alarms&#10;B) computer tomography alarms&#10;C) fire alarms&#10;D) special-use alarms

Accepted Answer

Computer tomography alarms are not a basic type of alarm system. The other three choices - intrusion alarms, fire alarms, and special-use alarms - are all common types of alarm systems.

Question 3

The common elements of all alarm systems include:&#10;A) an alarm sensor&#10;B) a circuit or sending device&#10;C) an enunciator or sounding device&#10;D) all of the above&#10;E) both b and c

Accepted Answer

All of the above options are common elements of alarm systems. Alarm sensors detect motion, sound, or other changes in the environment and send a signal to the circuit or sending device. This device then triggers the enunciator or sounding device, which is typically a loud siren, horn or bell, to alert people nearby. Therefore, all three elements are necessary for an effective alarm system.

Question 4

A fire resistant safe is also burglary resistant.

Accepted Answer

Fire resistant safes are designed to protect contents from fire damage and may not necessarily be built to withstand forced entry or burglary attempts. Burglary resistant safes have specific features aimed at preventing unauthorized access.

Question 5

Accepted Answer

According to safety regulations, all doors that can be used as exits during an emergency must be considered as emergency exits, including employee and visitor entrance doors.

Question 6

The doors on vaults are typically two inches thick.

Accepted Answer

Vault doors are usually much thicker than two inches, often ranging from several inches to over a foot thick, to provide enhanced security and protection against break-ins.

Question 7

Motion detections alarms operate by radio frequency or ultrasonic wave transmission.

Accepted Answer

Motion detection alarms can operate using various technologies, including radio frequency (RF) and ultrasonic wave transmission, to detect movement in an area.
