In apartment Buildings, real fire alarms are bad; false fire alarms are just as bad... or worse.
Problem: Cooking Smoke
Often it's called "burnt toast", but whether it's overcooked bacon or food left in the microwave oven too long, the smoke is still cooking smoke. The thing is when the smoke alarm sounds off from cooking smoke, it isn't a real fire.
It's just that there's enough burnt toast smoke to set off the smoke alarm.
Sometimes Burnt Toast Just Happens
When they're cooking, sometimes people burn their toast.
When the toast is burned in a house, the smoke alarm sounding in the house is all that happens; the person cooking fans out the smoke alarm and the alarm stops.
In an apartment building, when the toast is burned, the smoke alarm sounding in that apartment should also be all that happens. The person cooking fans out the smoke alarm and the alarm stops.
Apartment Building Fire Alarm System
Apartment buildings have a common area fire alarm system. These common area fire alarm systems watch for fires in the halls, in the basement, in the storage areas, etc. of the apartment building.
Everyone Hears the Common Area Alarms
These systems sound off because the escape route through the halls is starting to fill with smoke. Everyone hears these alarms.
When the common area alarms sound off, everyone should stop what they're doing and get out of the building. They should get out right away before the halls finish filling with smoke.
Real Alarm or False Alarm
Let's get back to the smoke alarm in the apartment. For the person with the "burnt toast", the smoke alarm sounding is a real alarm.
Bur for everyone else, the alarm isn't real. All the other people in the building shouldn't have to stop what they're doing and get out just because someone is cooking.
In the apartment building, for the burnt toast alarms to become a regular occurrence, each apartment only needs one cooking smoke alarm per year. If everyone has to hear this type of alarm over and over again during the year, it becomes annoying for everyone.
After a while, people don't stop what they're doing and don't leave the building anymore. If the alarm from a real fire sounds like someone is cooking, no one is even thinking of leaving until they smell the smoke. This is bad, because with a real fire, everyone needs to get out.
The problem is that by the time anyone can smell the smoke, the smoke has filled the halls. When the halls are full of smoke, there's too much smoke there to escape.
Smoke Alarms and Common Area Fire Alarms
To prevent cooking smoke from being false alarms for everyone, the apartment smoke alarms aren't connected to the common area fire alarm system. This way everyone doesn't have to react to someone else's cooking smoke.
