False Alarm 4
False Alarm 4 : Types of False Alarms: (1) Residential Burglar Alarms: (1. 1) Causes and Prevention: (1. 1. 1) Improperly Arming and Disarming of The System: This is typically caused by simple mistakes like entering the wrong passcode or letting too much time pass before entering the code. These types of false alarms can be prevented by taking more time to disarm systems, and entering a home with at least one hand free to properly disarm your system. (1. 1. 2) Untrained Users: Untrained users can be anyone who may need to temporarily access your home but is unfamiliar with your system. Common untrained users include cleaning crews, repairmen, dog walkers, or babysitters. Better educating temporary users about a particular system can prevent them from accidentally triggering it. (1. 1. 3) Power Problems: If a power outage occurs on system with a weak backup battery it can cause the alarm to trigger. Preventing this type of false alarm requires alarm owner to periodically replace the backup battery. (1. 1. 4) Pets: Some motion sensors will be triggered by pets moving around a home. This problem can be fixed by finding motion detectors that are not sensitive to infrared signatures belonging to anything less than eighty pounds, or by restricting the access of pets to rooms with motion detectors. Human arms, legs and torso all emit heat whereas a cat or dog only emits heat primarily just from their torso. Because of this a human's heat signature is different from that of more common household pets like the cat or dog. A pet immune motion sensor distinguishes between the two distinct heat signatures and ignores motion from the cat or dog. In cases however where a cat or dog can get within 6 feet from the pet immune motion sensor the sensor can still be tripped. Other factors such as the type of flooring, such as tile floors, will effect the immunity of a pet friendly motion sensor. Additionally, internal setting adjustments can be made to a pet friendly motion which have the effect of making the detector either too sensitive to pet motion or far less sensitive to any source of motion. Each of these factors should be taken into account when researching causes and solutions for false alarms in home security systems and installing a pet immune motion sensor
