A typical burglary occurs in less than 8 minutes. When a burglar hears a siren, he has to assume that the authorities are on the way. He quickly finishes up his crime and flees the scene. Almost all alarm systems are designed to automatically silence the siren after several minutes, because continuing to sound a siren serves no purpose other than to disturb the neighborhood with loud noise pollution. Even though your alarm system resets itself automatically, many types of false alarms can still result in extended or repeated siren soundings. Even high-end systems with advanced false alarm prevention features, such as swinger shutdown, can malfunction and generate noisy false alarms. And when the owner isn't around to disarm the system, neighbors have no choice but to endure the endless noise pollution! Types of false alarms include: TYPE 1. The siren turns on and remains on for an extended period of time. A false alarm of this type is usually caused by a malfunctioning alarm system circuit, possibly due to environmental factors or component failure. A properly operating alarm system should reset itself after several minutes and should not remain on for an extended period of time without interruption. TYPE 2. The alarm system retriggers continually. A false alarm of this type is usually caused by a malfunctioning sensor that repeatedly trips the alarm, causing the siren to sound over and over. Each time the alarm system resets itself, it is immediately retriggered by the malfunctioning sensor. TYPE 3. The alarm system retriggers intermittently throughout the day or night. A false alarm of this type is often caused by an overly sensitive sensor or human error. One example is a car alarm going off every time a truck drives by it. Another example is a home alarm sounding every time a pet moves about the house. PeaceMaker’s
built in microcomputer analyzes your alarm system’s triggerings and temporarily
silences your siren whenever any of these three types of extended or repeated
siren soundings occur. It then informs you that siren silencing
occurred in the previous 16 hours and the reason for silencing, so that
you can have your alarm system properly serviced. |
