Fires in large places will develop this. As the hot products of combustion rise from the fire, they expand and pull in cooler air from the surrounding area.
Fire Plume Development
Sloping ceilings have a rise to run of what
1 in 8
These types of fire detectors are often installed in or near hazardous (classified) locations.
Radiant energy fire detectors
These are the most common type of faults found when troubleshooting.
Wiring Fault
This certificate indicates compliance of the system and must be posed within 3 feet of the main system controls at the protected premises.
UL certificate
With this type of detector, most manufacturers require beams to be parallel to the ceiling so they pass through more of the plume.
Projected Beam Detector
These products delivered in unmeasured quantities are considered to be functional tests for smoke detectors.
Aerosol smoke
Insence sticks
punk sticks
Notification may be my means of what types of signals
Audible or visual
The owner must be notified in writing within this amount of time when a fire alarm system becomes disabled because of an impairment that cannot be repaired immediately.

DACT is the most common communication method because they use 2 lines of communication and requires transmission data of how long?
90 seconds
These areas of a dwelling are not appropriate for smoke detection
Kitchen

attics
bathrooms
Smoke detectors must undergo 2 types of tests. What are they?
Functional testing
Sensitivity testing
The maximum number of interconnected smoke detectors in a dwelling is what, if the smoke detectors cannot be connected between dwellings?

pg. 247
When the plume reaches the same temperature as the surrounding air, this occurs.
Stratification
This type of supervising station is owned and operated by the owner of the protected premises.
Proprietary Supervising Station alarm system
