Deck 42: Electronic Safety and Security

Question 1

____ detectors use beams of light to respond to smoke particles visible to the naked eye during development of a fire.

A) Photoelectric
B) Heat
C) Fire flame
D) Smoke

Answer 1

A

Question 2

____ use ultrasonic frequencies and microwaves to detect movement.

A) Intercom systems
B) Video surveillance systems
C) Intrusion detectors
D) Motion detectors

Answer 2

D

Question 3

List various methods of detecting fires.

Answer 3

A variety of signal sources act as alarm initiating systems by sensing the products of combustion at different stages of a fire's duration. Ionization detectors can detect microscopic particles emitted during the early stages of a fire. Photoelectric detectors use beams of light to respond to smoke particles visible to the naked eye during development of a fire. Heat detectors sense the actual fire   to immediately activate alarm and fire suppression systems. Fire flame detectors are used in occupancies where combustible materials that may burn are present. They detect the presence of either infrared or ultraviolet radiation.

Question 4

How do intrusion detectors work?

Question 5

____ detectors are used where combustible materials are present.

A) Heat
B) Fire flame
C) Smoke
D) Photoelectric

Question 6

____ use CCTV cameras mounted throughout a building to monitor problematic activity.

A) Intercom systems
B) Intrusion detectors
C) Visual surveillance systems
D) Motion detectors

Question 7

Describe electronic security systems.

Question 8

The core missions of a ____ system include keeping the building climate within a specified range, providing lighting based on established schedules, and monitoring system performance and device failures.

A) BAS
B) Doppler Effect
C) HVAC
D) CCTV
