28 ft
per the farthest point to a sidewall or corner to the detectors is 0.7 x the listed
spacing. In this case, the ceiling height is 10 ft. or less so we do not have to
reduce heat detector spacing due to ceiling height. The listed spacing is 40 ft. x
0.7 which equals 28 ft.
Light scattering. During a non-fire condition, light from the light source
does not provide light to the sensing device. When smoke enters the
smoke chamber, light from the light source reflects off the smoke and
when the light is sensed by the sensing device, an alarm is triggered.
FALSE : temperature falls outside of the recommended temperature range for
smoke detectors, a heat detector would be used.

0.77
per NFPA 72 2016, Table 17.6.3.5.1. For ceiling heights greater than 14 ft, up to and
including 16 ft, we multiply the heat detector's listed spacing by 0.77.

Term
Which type of smoke detector is best for special application areas
such as museums or data centers?
Give this one a try later!
Photoelectric smoke detectors, which are used for residential applications
Heat detectors, which are suitable for kitchens
Air sampling. Air sampling smoke detectors are normally used for
challenging or special environmental applications such as data centers,
cold storage areas, museums, or hospitals.
Ionization smoke detectors, which are best for open areas
