What Is a False Alarm<\/h2>
A false alarm is an event where a security system detects an activity that triggers a detection device, such as a motion sensor or smoke detector, without an actual cause or where the cause is a benign, unintentional circumstance.<\/p>
In the context of motion detectors, the term “false alarm” can be somewhat misleading. This is because most false alarms caused by these sensors still actually indicate a properly working sensor. <\/p>
Most motion detectors use heat-sensing technology, known as PIR motion sensors, to detect changes in a room’s heat index, which can indicate a new object entering the room. For instance, small animals may often create alarm events in warehouses and garages. Additionally, a burst of sunlight coming through a window can also create a motion event, as it replicates the heat caused by a person walking into a room. Surprisingly, even bugs can cause alarms if they crawl inside a detector. In these instances, the detector works as designed, even if it leads to an annoying “false” alarm.<\/p>
When a security system sends an alarm signal, the monitoring center cannot identify whether the event is a “true” alarm just by interpreting the signal. Therefore, dispatchers are trained to follow dispatch protocol based on the type of system the signal originated from. For example, in the event of a fire alarm, the monitoring center immediately dispatches the fire department to minimize response times. This “better safe than sorry” approach does save time, money, and lives, but dispatching on false alarms can overburden police and fire departments and distract from “actual” alarm events and emergencies.<\/p>
Why False Alarm Can Cause You Problems<\/h2>
False alarms in a home security system are not just a minor inconvenience. They can lead to significant problems that extend beyond the immediate annoyance. Here are some of the key issues associated with false alarms.<\/p>
Cost Implications<\/h3>
False alarms can be costly. Many jurisdictions offer leniency for first-time and second-time offenders, but repeated false alarms often lead to fines. These fines can reach up to $250 per occurrence and can quickly accumulate if the issue is not addressed promptly. <\/p>
Resource Drain for Emergency Responders<\/h3>
False alarms represent a significant drain on the resources of emergency responders. They are the most frequent type of call received by these services, and unfortunately, a large proportion of these are false alarms. This leads to unnecessary personnel and equipment costs and can delay the response to legitimate 911 calls.<\/p>
Wasting Emergency Services’ Time and Resources<\/h3>
When a false alarm is triggered, emergency services are often dispatched to the scene. This wastes valuable time and resources that could be better spent elsewhere. In addition, it can lead to a lack of trust in the alarm system by emergency responders, which can result in slower response times in the future.<\/p>
Distraction for Monitoring Centers<\/h3>
When an alarm is activated, the monitoring center is promptly notified. If the alarm is false, the attention of the monitoring center is diverted away from genuine alarms. This diversion can be dangerous as it can lead to slower response times in the event of a real emergency.<\/p>
Unnecessary Stress and Anxiety for Homeowners<\/h3>
Repeated false alarms can cause stress and anxiety for homeowners. This is particularly true if they occur at night when people are sleeping. Over time, this can lead to a lack of trust in the alarm system and can cause people to turn it off altogether, leaving them vulnerable to real threats.<\/p>
Damage to Reputation<\/h3>
If a home security company is associated with too many false alarms, it may get a poor reputation. This can affect their business and customer trust.<\/p>
Potential for Fines and Penalties<\/h3>
Many cities and towns have ordinances that penalize homeowners and businesses for frequent false alarms. These fines can be costly and can quickly add up if the problem is not addressed. In some cases, repeated false alarms can even result in the suspension or revocation of the alarm system’s permit.<\/p>

Impact on Community Resources<\/h3>
False alarms represent a costly issue for police, first responders, and communities as a whole. The costs associated with false alarms go beyond what you might think. They include personnel costs of police call takers and dispatchers, backup personnel and equipment costs, time and costs associated with analyzing false alarms, and lost-opportunity costs. False alarms can prevent police from responding to actual crimes. Most costs associated with false alarms are passed on to taxpayers.<\/p>
Causes of Motion Sensor False Alarms<\/h2>
Motion sensor false alarms can be triggered by a variety of factors. As the most common motion sensors utilized in home security systems are PIR motion sensors, we’ll mainly talk about the cause of PIR motion sensors unless otherwise specified. Here are some of the most common causes.<\/p>
Bugs and Insects<\/h3>
Flying or crawling insects, especially spiders, can trigger false alarms. They often make homes in corners and anchor their webs to the sensors. If they are big enough and crawl near the sensor, it can trigger a false alarm when there is no real emergency.<\/p>
Pets<\/h3>
Pets moving around in the detection area can cause false alarms. If homeowners have pets and don’t get sensors with pet sensitivity settings, there will probably be a lot of false alarms. Some motion sensors offer “pet immunity” features that ignore motion from pets.<\/p>
Air Currents<\/h3>
Curtains or plants blown by air conditioning or heaters can trigger the motion sensors as they are a significant heat source.<\/p>
Ceiling Fans and Other Moving Objects<\/h3>
The movement of ceiling fans can be detected by the motion sensors, causing false alarms. Although this is not very likely to happen to PIR motion sensor false alarms, if the ceiling fan can cause environmental heat changes, it can be caught.<\/p>
Human Error<\/h3>
Someone who is not familiar with the system or not properly trained can inadvertently trigger the alarm.<\/p>
Poorly Designed\/Installed Security Systems<\/h3>
If the installer does not consider the home, its occupants, and how they use the home, the system is more susceptible to false alarms. The system\/motion sensor should only monitor areas that might need to be monitored, not the living area of the homeowners.<\/p>
Lack of Maintenance\/Low Batteries<\/h3>
Although security system equipment generally doesn’t need much maintenance, it does need some. Otherwise, false alarms can be caused by factors such as low batteries if they are not hardwired for power.<\/p>
Outdated or Old Security Equipment<\/h3>
If it’s been a while since your security system was installed and you’re experiencing a lot of false alarms, your equipment may need to be replaced.<\/p>
Malfunctioning Security System Equipment<\/h3>
Although relatively rare, there’s always the chance that the equipment itself is actually jammed or malfunctioning, and that’s what’s causing the false alarm.<\/p>
Heat Changes<\/h3>
Some sensors can track infrared radiation. This means a motion detector will be able to detect a light that has been turned on because of a shift in temperature.<\/p>
White Light Momentarily Blinding the Detector<\/h3>
White light momentarily blinding the detector can cause false alarms because natural light is infrared radiation.<\/p>
Unlocked Doors and Windows<\/h3>
This may seem like a no-brainer, but knowing that everything is locked before going to bed or before leaving the house ensures that a gust of wind won’t cause a window or door to become ajar. The hot wind or IR leaked from the door and windows can trigger a PIR motion sensor.<\/p>
Improper Installation<\/h3>
When a home security system is installed, it’s vital that all detectors and sensors are correctly aligned and that equipment is installed according to the manufacturer’s recommendations.<\/p>
RFI\/EMI Signals<\/h3>
RFI\/EMI signals can cause false alarms to active sensors.<\/p>
Causes of Doors & Windows False Alarms<\/h2>
False alarms from door and window sensors can be a common issue in home security systems. These false alarms can be attributed to a few key causes.<\/p>
Sensor Misalignment<\/h3>
Door and window sensors function by aligning a contact with a magnet. When the door or window opens, the magnet loses contact with the sensor, triggering an alarm.<\/p>
However, weather-related wear and tear can cause doors and windows to shift from their frames, increasing the gap between the sensor and the magnet. This increased gap can lead to false alarms as the magnet may no longer maintain a consistent connection with the sensor.<\/p>
To troubleshoot these false alarms, it’s important to check the gap between the contact and the magnet. Adjusting the position of the contact or repairing the door or window frame can often resolve this issue.<\/p>
Overly-Sensitive Glass Break Detectors<\/h3>
Glass break detectors are designed to trigger an alarm when they detect the sound of breaking glass. However, these detectors can also be set off by other loud noises, such as a door being kicked in, dogs barking, or objects falling over. If your glass break detectors are overly sensitive, they may be prone to false alarms.<\/p>
To prevent this, it’s recommended that you discuss the sensitivity settings of your glass break detectors with your security technician. They can adjust the sensitivity to ensure it only responds to the sounds it’s meant to detect.<\/p>
Unsecured Doors and Windows<\/h3>
It may seem obvious, but ensuring that all doors and windows are securely closed and locked can prevent false alarms. A gust of wind or a slight nudge can cause an unsecured door or window to open, triggering an alarm. Establishing a routine to check all doors and windows before leaving the house or going to bed can help prevent these types of false alarms.<\/p>
Causes of Smoke Detector False Alarms<\/h2>
Smoke detectors provide early warning of potential fire hazards. However, they can sometimes trigger false alarms, which can be both annoying and potentially dangerous if they lead to complacency. Here are some common causes of smoke detector false alarms.<\/p>
