Security systems are intended to alert you and your family of potential dangers. Because of this important function, most alarm systems notify you if there is trouble in the system. There are numerous causes for system trouble; low batteries and open security zones (doors and windows) are common. If the system is experiencing trouble, you will typically notice a beeping sound coming from the system or its components.
Check your alarm panel, fire alarms and other sounding devices connected to your system carefully to discern where the beeping is coming from. If the beeping is not coming from your system or one of its components, the trouble lies somewhere other than the security system.
Press the "Silence" button on the alarm panel. While alarm panels differ in make and type, many have a "Silence" button to stop the beeping.
Enter your security code. Typically, your security code is a four-digit number. Entering your code often silences alarms if pressing "Silence" fails or if your system does not have a "Silence" button.
Close all security zones--windows and doors--and arm and disarm your system. If the beeping continues, try arming and disarming the system again to clear out any trouble signals. Often, an alarm system will continue to beep after an alarm has just sounded; many systems beep to notify you which zone was triggered.
Locate the security system's power source (typically a black case inside a closet or crawl space) and remove the wire-leads from the backup battery. Insert a new backup battery and replace the leads. Systems typically use a 6- to 12-volt battery.
Unplug the security system from the wall and remove the wire-leads from the backup battery; this will completely power down your system. Do this only if your security provider advises that it is OK.
Check the wiring of your security system with a voltometer. Look for faults in the wiring; some of the wires may have become corroded. Only proceed if you have experience handling electrical components; contact an electrician or your alarm service provider for assistance.
Contact your alarm security provider and ask for further assistance, if necessary.
