How Can the Sensitivity of Burglar Alarms Be Changed to Reduce False Alarms


Burglar alarms are critical for protecting homes and businesses, bringing us peace of mind by warning us to prospective intruders. However, false alerts can be inconvenient, creating unneeded tension and wasting precious resources. Fortunately, there are techniques to alter the sensitivity of burglar alarms to reduce false alarms while keeping them effective. We’ll discuss ways to optimize burglar alarm sensitivity in this article.

Burglar Alarm Sensitivity

Before getting into adjusting strategies, it’s important to understand how burglar alarm sensitivity works. Most alarms detect unauthorized access or movement using sensors such as motion detectors, door/window contacts, or glass break sensors. Sensitivity relates to the degree of detection capabilities, which determines how quickly an alarm is triggered by ambient conditions or intruders.

Common causes of false alarms:

False alarms may occur for a variety of reasons, including:

  • Pets: Household pets, particularly cats and small dogs, can activate motion sensors.
  • Insects: Flying insects or spiders can accidentally trigger motion detectors.
  • Environmental Factors: Temperature changes, sunlight, and strong winds can all activate sensors.
  • User Error: Incorrect system configuration or failure to disable the alarm can result in false alarms.

Adjusting Sensitivity Settings

  • Pet Immunity Sensors: Consider adding pet-immune motion sensors, which are designed to disregard movements under a certain weight threshold. This prevents pets from causing false alarms when detecting intruders.
  • Range Adjustment: Most motion sensors allow you to change the detecting range. To reduce false alarms from ambient elements like moving branches or autos, restrict the field of view or detecting distance.
  • Dual Technology Sensors: Dual technology sensors use multiple detecting technologies, such as infrared and microwave, to limit false alarms. These sensors require simultaneous activation of both technologies, which improves dependability and reduces false alerts.
  • Test and Calibration: Regularly test and adjust your burglar alarm system to ensure peak functionality. Follow the manufacturer’s instructions to test individual sensors and modify sensitivity settings accordingly.

Professional Assessment and Maintenance

If you’re unsure how to modify the sensitivity levels or are receiving many false alarms, try seeing a skilled alarm expert. They can thoroughly examine your system, detect potential flaws, and fine-tune settings to successfully reduce false warnings. Furthermore, frequent maintenance and service can help to avoid false alarms caused by sensor malfunction or wear and tear.

User Awareness and Education

When it comes to reducing the number of false alarms, proper user education is absolutely necessary. Ensure that everyone who has access to the alarm system understands how to use it properly, including the arming and disarming processes. Keep pets away from motion sensors and avoid placing objects in front of detectors to prevent false alarms.
