Have you recently installed an alarm that keeps going off for no apparent reason? False alarms are a
fairly common problem for alarm owners. They are usually caused by an incorrect assessment by detectors, which detect heat, movement or displacement that is not really present or is caused by natural phenomena. Such disturbances generally have two main sources: natural or artificial. A classic natural cause is wind entering through a window and slamming a door, setting off an alarm even though nobody is trying to enter. If you need to replace your alarm system, consider dual- or triple-technology motion detectors: these alarms activate
only when several detection factors are triggered, increasing tolerance of unpredictable events such as thunderstorms. Another common trigger is pets. Devices are sometimes not calibrated to let dogs and cats move freely. Artificial causes of false alarms include
accidental or deliberate power cuts and battery or control-panel faults. If wires break or power drops, the battery takes over.
