How do personal alarms work?

Personal alarms are small, easy-to-use devices that alert those around you of an emergency. Whether in everyday life or a hazardous situation when exploring the outdoors, having a personal alarm on your personal self defense tool arsenal can make the difference in getting help quickly and safely. In this blog post, we’ll explore how personal alarms work, what features they have, and why it is important to keep one with you at all times.

What is a Personal Alarm, and how does it work?


In general, a personal alarm is a small device that emits an extremely audible sound when activated. The sound emitted can range from 100 to 130 decibels, depending on your chosen model and how loud the alarm needs to be. When the alarm is triggered, it will generate a loud noise which should attract attention and alert those nearby of your emergency. Nowadays, there are also smart personal alarms that can send silent distress signals with your location via text message to pre-selected emergency contacts,

You can press a button or pull on a cord to activate the alarm. Depending on the type of personal alarm you have, it can detect motion or vibrations and emit a warning without having to press any buttons. This means that you can always keep your notice with you, whether in your pocket or on a lanyard around your neck, and it will be ready to use in an emergency.

Personal alarms come with various features, including built-in LED lights, sirens, or even tracking devices that can help rescuers track down your location. Some models have rechargeable batteries, while others require disposable batteries which can be replaced easily.

3- Larger personal alarms can be used in outdoor situations and feature a longer range of sound, ranging from 130 to 140 decibels. These devices are often accompanied by a siren and LED light, making them ideal for more hazardous scenarios where you may need to attract attention from further away.
