We have a smoke alarm in every room except the bathroom and kitchen. In the kitchen we have a 'heat' alarm so if you burn some toast it doesnt give you a headache

The smoke alarm in my apartment is right above the kitchen.

I have no idea how to turn it off and if you dont do so within so many minutes it sets it off in the whole building

Have you rounded off all sharp edges in the house too?

Mine is battery powered, wired into the flat, wired into the building, wired into the backup building



As we found out to our cost when an empty flats starting going off a few weeks ago and went off all weekend

There called "Smoke Detectors" technically, and its actually difficult to detect a naked flame; it is also difficult to detect temperature rises without being annoying; ie the alarm going off everytime you have the heating on.

They work using Beta Radiation between two points; if the Radiation flow is broken by smoke, a circuit is completed and the alarm goes off.

Ionization detectors have an ionization chamber and a source of ionizing radiation. The source of ionizing radiation is a minute quantity of americium-241 (perhaps 1/5000th of a gram), which is a source of alpha particles (helium nuclei). The ionization chamber consists of two plates separated by about a centimeter. The battery applies a voltage to the plates, charging one plate positive and the other plate negative. Alpha particles constantly released by the americium knock electrons off of the atoms in the air, ionizing the oxygen and nitrogen atoms in the chamber. The positively-charged oxygen and nitrogen atoms are attracted to the negative plate and the electrons are attracted to the positive plate, generating a small, continuous electric current. When smoke enters the ionization chamber, the smoke particles attach to the ions and neutralize them, so they do not reach the plate. The drop in current between the plates triggers the alarm.

Both ionization and photoelectric detectors are effective smoke sensors. Both types of smoke detectors must pass the same test to be certified as UL smoke detectors. Ionization detectors respond more quickly to flaming fires with smaller combustion particles; photoelectric detectors respond more quickly to smoldering fires. In either type of detector, steam or high humidity can lead to condensation on the circuit board and sensor, causing the alarm to sound. Ionization detectors are less expensive than photoelectric detectors, but some users purposely disable them because they are more likely to sound an alarm from normal cooking due to their sensitivity to minute smoke particles. However, ionization detectors have a degree of built-in security not inherent to photoelectric detectors. When the battery starts to fail in an ionization detector, the ion current falls and the alarm sounds, warning that it is time to change the battery before the detector becomes ineffective. Back-up batteries may be used for photoelectric detectors.

Are you jokeing? i bloody hope so


No Im serious

When you're asleep and there is a fire in the house, it's the smoke that will kill you, not the heat or flames.

Hence the name of a 'smoke' alarm and not a 'fire' alarm.

Omfg

If there's a bairn involved, you shouldn't take your fire alarm doon.
