What Our Customers Are Saying

Michelle S.

Verified Buyer

Very pleased with these INSANELY loud alarms!

"I purchased these because my mom is always walking early in the morning and also for myself because I am often in a train station parking garage at 2am alone. My mom said she felt a lot safer while carrying this with her pepper spray and I think that's great."

What is the purpose of personal alarms?

The intent is to surprise and disorient an attacker, allowing a few precious seconds you need to get away, while drawing attention to your situation.

Who should carry a personal alarm?

Certainly anyone who is out by themselves on a regular basis. It is a great gift for an older or elderly person who has limited mobility as they can use it to draw attention if there is a problem such as a slip and fall. Personal alarms are also ideal for children.

How loud is it?

Most top out at about 130 decibels. That is as loud as a jet engine at 50 feet and sufficient to cause temporary disorientation to anyone standing within a few feet.

Does it come with a carabiner?

Yes, each Original Defense Siren comes with a carabiner for the utmost carrying and storage convenience.

Is this water resistant?

Yes, the Original Defense Siren is in fact water resistant. While it should not be fully submerged in water, it can remain functional in various weather conditions such as rain and snow.

How do you start the alarm?

For the siren to activate, pull out the pin on the top of the device and to deactivate, just reinsert the pink back.
