Q

Ultrasonic/microwave motion detectors

A

work like radar. they know how long a wave ‘echo’ should take to return. When a person or something passes in front of them - then the echo takes less time and motino is detected.

surge
prolonged high voltage
26
spike
temporary high voltage
27
sag
temp low voltage
28
EMI
electromagnetic interference.
29
crosstalk
EMI affecting cables' communication
30
Positive pressure and drains
All HVAC should be positive pressure.
31
HVAC Heat and humidity
``` humidity = 40-55 percent heat = 68-77 degreesf ```
32
Static and corrosion
low humidity = static | high humidity = corrosion
33
Airborne contaminants
dust. Positive pressure and HEPA to control this
34
Heat detectors
alert to high temps.
35
Smoke detectors ionization
uses small radioactive source to create an electric charge. Alerts when smoke interrupts radioactivity
36
Smoke detector photoelectric
Uses an LED and a photoelectric sensor. Alerts when dust blocks light from sensor.
37
Flame detectors
detects infrared or UV light from fire. Usually needs line of sight.
38
Evacuation routes
should be prominently prosted. Sites should have a meeting point.
39
Evac roles and procedures
Safety warden - ensures that all personnel safely evacuate. Meeting point leader - assures all personel make it to the meeting point.
40
Duress warning system
Way to inform employees of an emergency. Paging systems are often used.
41
Travel safety
Ensure employees are safe while commuting
42
A fires
common combustibles, paper, wood. Extinguish with water or soda acid.
43
B fires
Liquid for flammable gases: burning alcohol, oil, other petrol products. Extinguished with gas (co2) or soda acid
44
Class c fires
electrical fires Gas should be used to extingusih - i.e. Halon, CO2
45
Class d fire
burning metal extinguished with dry powder
46
Class K fires
kitchen fires. extinguish with wet chemical
47
Water as a suppression agent
recommended for Class A fires.
48
Soda Acid
baking soda + acid creates CO2 and foam = both are fire suppresant
49
Dry powder
Lowers temp and starves of oxygen
50
Wet chemical
Usually potassium acetate mixed with water. covers a greas or oil fire in a soapy film that lowers the temp
51
C02
smothers fire. Can also suffocate unwitting employees
52
Halon
causes chemical reaction with the fire that consumes enercy and lowers temp. Halon is being phased out but has substitutes.
53
Montreal Accord
Source of phasing out Halon. Halon = Ozone holes = bad. Existing halon can be used, no new halon can be produced.
54
Halon replacements
Argon FE-13 FM-200 Inergen
55
Halon replacements
Argon FE-13 FM-200 Inergen
56
Count down timers
Needed before gas is released
57
Wet Pipe ______ system
sprikler system. Water right up to each sprinkler head. Each head triggers independently
58
Dry pipe _______ system
sprinkler system Pipes are filled with compressed air. as heads open - pressure drops allowing upstream valve to open. Often used where pipes could freeze
59
Deluge _____ System
sprinkler system. pipes are empty until a fire alarm goes off then all sprinklers go. sprinkler system. simliar to dry pipes, except sprinkler head are already open and larger than dry pipe heads. pipes are at normal pressure.
60
Pre-action ______ system
combo of wet, dry, or deluge systems. require two separate triggers to release water.
61
Single interlock preaction sprinkler
releases water into pipe on fire alarm. Water is release when head is triggered.
62
double interlock preaction sprinkler
uses compressed air in pipes. water doesn't enter pipe until both an alarm goes off and a sprinkler head opens
63
PASS
pull the pin aim low squeeze the pin sweep the fire.
64
Gates
Deterrent and/or Preventative. Range from Class I (deter access) to Class IV (Prevent a car from crashing through.)
65
Lights
Deterrent or Preventive. Now measures in Lux, historically measured in foot-candles.
66
CCTV
Mostly detective, can be preventive.
67
Locks
Preventive control
68
Walls, Floors, Ceilings
any internal secure perimeter should start at floor slab and run to ceiling slab. Called "slab-to-slab" Raised floors and drop ceilings obscure where walls and ceilings really start/end.
69
Guards
Can be preventive, detective, and physical control
70
Dogs
detection and detterent. High liability.
71
Site Marking
Building is not marked, or very modestly marked to attract the least amount of attention.
72
Shared Tenancy and Adjacent Buildings
Neighbors and neighboring building may offer an attack vector to a threat. Should be considered.
73
Shared Demarc
Typically all tenants in building go through the same demarc. CIA Concern.
74
Media Storage Facilities
Best be outside main facility, AND not possible to be impacted by a disaster at the main facility.
75
CPTED Acronym
Crime Prevention Through Environmental Design
76
Swell
Prolonged High Voltage
77
Security Categories vs types
Categories: Administrative Technical Physical ``` Types: Preventive Deterrent Detective Corrective Recovery Directive ```
