An Alarm went off this morning at 6:30am the funniest part that after I flush the toilet an alarm went off and I thought I set off an alarm after flushign the toilet lol but really me andmy sister have no ideal what happend so, we called our alarm company told than what happend and they said the bettery is low That sodumb why alarm have to go off just to tell us that bettery is low? because taht is false alarm. Dose anyone know of a new type of Berglar alarm that let you know the battery is going low WITHOUT setting an alarm off? we have ADT and they are good company.

Do you always spell that way?

Each of your sensors (reed switches on window / door frames operated by magnets on the window / door are traditional) should be arranged to *break* the circuit under alarm conditions. All these sensors are wired in series. Cutting the wire will cause the alarm to sound. Your control panel needs to contain a rechargeable battery, so that it will still work if the supply cable is cut. You need a simple logic circuit that will sound the alarm if the voltage on the input drops (meaning that one of the sensors has operated, or the wires have been cut). The control panel needs to be wired up to the sensor circuits, the outdoor alarm box and a power supply (a plug-in mains adaptor is as good as anything). Have a second rechargeable battery pack inside the outdoor alarm box. Take the charging supply to the battery via a resistor and diode. (This battery needs to be a lower voltage than the one inside the control panel, as the resistor and diode will create a voltage drop. It should also have a lower mAh rating to ensure it doesn't hog all the charging current.) Monitor the voltage upstream of this diode (feed it via a resistor into a logic gate, or the base of a transistor, depending how you built the circuit. For instance, if you build a siren with two op-amps as oscillators, one modulating the reference voltage on the other one which feeds a speaker via a transistor, you can use the charging supply to turn on a transistor which shorts out the timing capacitor in the main oscillator and cuts off the oscillation, therefore silencing it). If there is no voltage there then you need the alarm to sound as it means the wiring to the control panel has been cut.

YOU KNOW U ARE MISSING THE BLESSING HERE. THE ALARM WENT OFF TO WARN U THAT IT IS TIME TO CHANGE THE BATTERY. IT SOUNDS LIKE A GOOD WARNING SYSTEM. ADT SHOULD NOT CHARGE U FOR THAT OR CONTACT THE FIRE DEPT. IF U CALLED THEM. THANK GOD FOR WHAT U HAVE AND WHAT U LEARNED

Contact ADT and ask them where the battery is located, how to access and what kind of battery...Should be an easy fix? Then you would have to put in codes....there is a procedure for that...maybe they should send someone out...
