Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
Alpha radiation is emitted from the amercium button in a smoke detector. When smoke goes into the smoke detector it blocks the stream of alpha particles emitted from the americium. That triggers an alarm.
If the smoke alarm goes off because of steam or smoke from cooking, the alarm should be moved to a better location or a different type of sensor used. It is very dangerous to have too many false alarms because people tend to ignore them, until the one time it really is a fire, and then it may be too late. If a smoke detector makes an intermittent "chirp", not a loud and continuous alarm, it may be signalling that it is time to replace the battery. Smoke detectors should be replaced every ten years, even if they still seem to be working, since they are only designed for a limited useful lifetime.
An alarm clock will typically beep for about an hour when it goes off. This is if the alarm is not turned off first.
advantages:They save lives, they are cheap, easy to fit , reliable disadvantages: Radioactive material( in ionising smoke alarms which releases alpha particles) nucience alarms ( when the alarm goes of because of cooking or burnt toast)
There are a lot of fire alarm systems depending what kind of an alarm system you want.Fire alarm system with (smoke detectors,heat detectors,flame detectors almost the same with heat detectors,ionized smoke detectors and duct detectors) depending on the system of your needs.For you to understand it I will explain 2 of it.Smoke detectors have smoke sensors in side if the smoke is too much the alarm system starts to work,that means alarm works.How the alarm works the smoke detection system analysis the air which goes through it , if the sensor senses any increase of CO or CO2 then it starts the alarm. Flame or heat detector has a contact which is made of 2 different materials which has different specific heat, İf any heat reaches to this contact according t the different specific heated material contact bends towards the more specific heated material( you can do it with copper and iron at home if you fix them with a nonmetallic material and heat them even with a lighter you will see it with your eyes) than the alarm starts because the contact touches a metallic material to give the energy to the horn or bell.( for more specific information try Notifier or Honeywell

Easy, an alarm.

my alarm goes off at random times. i had the alarm module changed for $700 and it still goes off. come home from work at 4 and it goes off at 10. before the alarm module was changed it went off at 12, 2 and 4 in the morning.
a constant beep is the overheat alarm a beep that goes in and out is low to no oil alarm
