The Personal Alarm
Keeping 800,000+
Families Safe
The #1 rated personal alarm in the USA. This tiny device packs an ear-piercing siren and a bright strobe to scare off attackers and bring help fast, and that’s why most customers grab more than one.
Heard up to 1,000 feet away
So people can find you, even in the dark
Carried by families in every state
Goes where pepper spray can’t
Ships From the USA
I bought these for my mom, who walks early every morning, and for myself, because I’m often alone in a
train station parking garage at 2am. We both feel a lot safer carrying one.

Watch What Happens
In 3 Seconds. A 130 dB siren and a flashing strobe, instantly.
It startles an attacker, buys you the seconds to
get away and tells everyone nearby where you are.
Reasons You’ll Love the
Original Defense Siren
It’s small enough to forget it’s there and loud enough that nobody can ignore it. No training, no aiming and
no monthly fees, so anyone in the family can use it.
The #1 Brand Trusted by the Police
A personal alarm has to work the first time, every time. That’s why law enforcement officers across the USA urge families to carry one for every member of the household, and why so many choose the Original Defense Siren.
Deter Attackers in Dangerous Situations
You never know when the moment will come. Pull the pin and a 130 dB siren goes off right at the attacker, loud enough to startle and disorient them so you can get away. Attackers look for easy, quiet targets, and this makes you neither.
Alert Others If You’re in an Emergency
The alarm can catch someone’s attention from up to 1,000 feet away, and the strobe shows them exactly where you are. Many self-defense classes recommend an alarm you can set off the moment you need help.
So Easy Anyone Can Use It
There’s no app, no button sequence and no skill to learn. Hook a finger through the ring and pull. It works for kids, teens, grandparents and anyone with a weak grip. Push the pin back in to stop it.
Instant Access Could Make All the Difference
Every Siren comes with a free carabiner clip, so it rides on your bag, purse, belt loop or keys, right where your hand can find it. Many customers keep extras in the car, at work, or give them to the people they love.
Bring Safety Wherever You Go
Unlike pepper spray or knives, the Siren can go almost anywhere: school, the office, concerts and in your carry-on. It’s legal in every state, and there’s nothing to aim and nothing that can be turned against you.
COLLEGE STUDENTS
Late library nights and the walk back across campus. It clips right to the backpack.
RUNNERS & WALKERS
Early mornings and quiet trails. It rides on a key, a waistband or a shoe lace.
NIGHT-SHIFT WORKERS
Nurses, servers and anyone heading to the car at 11pm.
KIDS & TEENS
Walking home from school or the bus stop. No phone needed, nothing to figure out.
PARENTS & GRANDPARENTS
Errands, the mailbox and the garden. One pull brings help if they slip or feel unsafe.
COMMUTERS
Parking garages, train stations and dark lots after work.
DOG WALKERS
Before sunrise and after dark. It clips right to the leash.
DRIVERS
Keep one on your keys and a spare in the glove box.

Why a Siren Instead of
Pepper Spray?
Pepper spray has to be found, aimed and sprayed into the wind, and it’s banned in a lot of the places you go. The Siren just has to be pulled.
