If you’re wondering, “Why is my security system giving false alarms?”, the most common causes include human error, pets, environmental changes, power problems, poor installation, incorrect sensor placement, and entering the wrong code. A false alarm happens when your system detects and sends an emergency signal, but nothing has actually happened.
For example, your dog walks past a motion detector and sets off the alarm, and this is not an emergency.
Repeated false alarms can lead to local fines and waste emergency responders’ time. Here, we’ll cover what causes the problem, how to stop it, and when to call for repairs.
What usually causes a false alarm?
If your alarm system keeps going off, something small is usually setting it off. The first step to prevent false alarms is identifying the causes. A loose door sensor could register a closed door as open. Entering the wrong code can also cause alarms when there’s no break-in.
- Pets triggering motion detectors: Pets moving around the room or jumping onto furniture can set off a motion detector.
- Human error: Most false alarms come down to user error. Someone unfamiliar with the system or the wrong passcode can trigger a false alarm.
- Loose or misaligned sensors: When doors and windows are not shut properly, wind can disrupt the sensors and alarms.
- Low batteries: Weak batteries can cause low-battery alarm beeping, which warns that a sensor or the control panel needs attention.
- Environmental changes: Bad weather, temperature changes, and direct sunlight can cause false alarms in motion-detecting cameras. A draft or moving object, like curtains, can trigger a false alarm. Insects or birds crawling or flying close to the sensors can also set off an alarm.
- Poor installation: Misaligned sensors, improperly installed sensors, incorrect wiring, faulty equipment, or the wrong type of motion sensor used in the wrong setting can cause a false alarm.
- Incorrect placement: Placing a smoke detector too close to a heat source or bathroom can cause a false alarm. A motion sensor too close to a heating or cooling vent can also cause a false alarm.
How to reduce false alarms at home or work
Everyone who uses the system should know how to arm and disarm it, enter their code, and handle an accidental alarm. When considering how to stop false alarms, a few simple checks and fixes can help. To keep your home and business secure, follow these steps:
Check sensor positions: Check if door sensors are misaligned. Ensure door and window sensors are firmly attached. Also check that motion detectors are at the right height. Repositioning a camera or smoke detector can also eliminate a false alarm.
Replace batteries on schedule: Once you notice signs of a low battery, replace the control panel and wireless device batteries. CornerStone’s alarm system battery replacement guide explains signs that a battery needs attention.
Adjust motion detectors for pets: Consider using pet-friendly motion detectors and smart motion-detection cameras.
Train staff and other users: Train everyone involved to use the system, arm and disarm it, and enter the passcode correctly.
Know what to do after entering the wrong code: If you accidentally trigger the alarm, re-enter the correct code to silence and disarm the system. When the monitoring center calls, give them your verification password.
Check and clean sensors: Gently dust off the smoke detector, wipe down motion sensors, and check inside for trapped insects.
Regular updates: Test your alarm system regularly and update your system software to ensure it functions properly.
Proper installation: Contact a professional security company to avoid improper setup and false-alarm-related security system issues.
Professional monitoring helps reduce false alarms
With professional monitoring, your system is connected to a monitoring center and is supervised by trained responders. If an alarm is set off, the center reviews the signal first, then contacts the designated number before dispatching the police.
CornerStone Protection provides UL-listed monitoring and Enhanced Call Verification (ECV). Shannon’s 28 years of law enforcement experience helped to achieve this milestone.
24/7 monitoring by real people helps reduce false alarms and answer the question: why is my security system giving false alarms?
ECV offers multi-step verification by calling two different phone numbers to help verify a burglary alarm before requesting police. Keep your contact numbers current, and make sure backup contacts know the verification password. If you miss the first call, another authorized contact may be able to explain what happened and provide the verification code.
With remote video monitoring in business, specialists can check camera feeds and assess the situation.
Time to call for security system repair
Call a security system repair professional if false alarms persist after basic checks. If a sensor stops working, battery warnings return after replacement, or camera footage is blurry, it also needs attention.
Signs include:
- If there is a wiring fault or power issues, then don’t try to fix it yourself.
- If the same door, window, or motion detector keeps setting off the alarm without an obvious cause.
- If sensors stop responding and the alarm panel keeps beeping without any visible reason.
- If your keypad is broken and you can’t arm or disarm the system, then call for help.
Check if your camera footage is blurry or if cameras keep going offline. If it helps, read about security camera repair to understand the issues.
