The Differences and Similarities between Ionization and Photoelectric Smoke Detection Technologies - Assignment Example

The radioactive material that the air comes into contact with causes the air to become a conductor. This system works on a totally different basis from Photoelectric smoke detection. As the name connotes, the photoelectric system works by sensing the environmental light that enters the detection chamber. The light that enters the system is scattered and triggers the alarm sensor to emit a warning sound in the room. While the light obscuring type creates a less intense type of light as it detects the smoke in order to sound the alarm.

Owing to this comparison, I believe that the photoelectric technology is most trustworthy since I understand how light works. I know nothing about radioactive materials and would not be comfortable around that technology. I find it dangerous and would not risk exposing my family to its well-known dangers. What are two of the major requirements for detector placement according to NFPA 72 in residential occupancies?The NFPA 72 dictates that in residential occupancies, fire alarm boxes should be no further than five feet from the nearest exit and be only between 42 -48 inches from the floor.

Both sides of the existence should have existing fire alarms in an open space of approximately forty feet in width. The distance between the alarms should not be more than 200 feet from each other when installed in big rooms or hallways. For visibility, the fire alarm bells should be red except in instances when the wall itself is painted red. In such instances, the alarm bell should be painted silver. What are the considerations for the placement of a smoke detector?Just like with anything that must be installed, one must consider the needs of the environment before a smoke detector is installed.

For example, in a tall, multi-floor room, a beam smoke detector would work best. Small indoor rooms with low ceilings will suffice with a spot detector. Heat-activated detectors are most efficient in a room that could have chemical fires due to the high heat emitted by burning chemicals. With all of the available types of smoke detectors, it is important to remember that the smoke detector that will work best is the one that best suits the environment it will be installed in.
