How The Door Alarm works: When a monitored door is opened the transmitter sends a signal to the receiver/alarm that plugs into any standard AC wall outlet in your bedroom, kitchen, den, etc. You can use one set to guard one door or buy extra transmitters (Item No. 0067) to monitor two, three or more doors. Additional receiver/alarms (Item No. 0066) can also be purchased separately and placed in different areas of the house to add extra assurance that no alert will go unheard. All of them will sound if any monitored door is opened.
This is a simple alarm that will beep when someone enters the door in your bedroom. It is cheap and easy to make. It will beep as loudly as you want, depending on the buzzer you use. It is also very easy to deactivate. This is an advantage if you just want something to give you a heads up when someone enters your room. It can be a disadvantage if you want an alarm that will alert the whole neighborhood. After all, an intruder could disarm it as easily as you could.

A closed door provides protection from smoke on the other side, but will also prevent smoke from reaching a smoke alarm. This is particularly a problem in bedrooms. If you sleep with your bedroom door closed, you should add a smoke alarm in the bedroom; particularly if you smoke in the bedroom or there is a TV, air conditioner, or other major appliances in the bedroom that might start a fire. If you sleep with the bedroom door open, the alarm in the hall outside will detect a fire in the bedroom or elsewhere.
