Who invented the alarm clock, I'll give lots of stars ;) x
Smoke detectors sometimes become dirty and need to be vacuumed out. They also will chirp when a fault is detected. The cheapest way is to clean it with a vacuum. If this doesn't solve the problem you should upgrade to the new beam sensor detectors. These are more reliable. My detectors are hard wired in my house with no batteries. I have never seen a detector hard wired with a battery back-up? Also if you replace them don't throw them in the trash as they must be disposed of at a hazardous depot, usually free of charge.
Between work and home I'd say thousands a day, yes I have to have rest stops
Common thieves do not disable home alarms. To disable alarm systems SOPHISTICATED thieves use knowledge gained from studying the ill obtained classified literature of the companies that produce the home alarms that they anticipate encountering. For goodness sake be careful.
