What happens when you pull.
Everyone hears you
Siren and light at once, even without a phone. Push the loop back down and it all stops.
Help gets called
With your phone paired and its SOS set up, it calls the emergency services on its own after a few seconds.
Your people know where you are
They get your location through your phone, depending on its settings and signal.
Set it once, and stop thinking about it.
The siren works on its own. These three steps add the emergency call and the message to your people.
See the step-by-step guideTick them off as you go.
Pair it with your phone.
Press the side button until it beeps. On your phone it shows up as “SOS Personal Alarm”: that is yours.
Choose who to alert.
Your people stay in your phone, we never see them.
Let the call go out on its own.
One setting on your phone, and no need to unlock it.
Loud enough to turn heads.
130 dB at 30 cm. To give you an idea of what that sounds like:
130 dBimpossible to ignore
- 60 dBA conversation at the table
- 80 dBA busy avenue at rush hour
- 110 dBA nightclub doorway
- 130 dBOYA at arm’s length
- 140 dBA jet engine from the tarmac
Approximate reference points: the sound you hear depends on distance and surroundings.

What you should know, no small print.
We would rather tell you before you order.
Your phone makes the call.
The siren and light work on their own. The call and your location go through your phone and its network.
Keep your phone close.
Within about ten metres, everything goes out. Further away the siren still sounds, and the call waits until your phone is back in range.
Keep it away from water.
OYA is not waterproof. If it gets wet, dry it before charging it.
In danger, call for help as well.
OYA makes you heard, it does not replace a call to 112.
Still have a question?
Short answers here. And if that is not enough, we will answer you.
Ask us a questionHow do I pair OYA with my phone?
Hold the side button until it beeps and the Bluetooth comes on. In your phone list the device is called “SOS Personal Alarm”, not OYA, which is normal. The setup guide walks through the iPhone and Android settings step by step.
How do I stop the alarm?
Push the loop back down. The loop stays attached to the device, so there is nothing to put back and nothing to lose.
Do I have to unlock my phone?
No. OYA talks to your phone over Bluetooth, so pulling the device raises the alert on the spot.
How loud is the alarm?
130 dB, roughly a jet engine at close range. Loud enough to turn heads and bring help your way.
Will it work in another country?
Yes. Your phone’s SOS dials the emergency number of the country you are standing in, as long as your phone and network allow it.
How far does the Bluetooth carry?
Ten to fifteen metres as a rule, depending on what is around you.
All that is left is picking its colour.
A small thing on your keys, so you can head out feeling calmer.

Their words, as written.
Petit mais Puissant. Alarme discrète et super Efficace. Je rentre souvent chez moi tard le soir et je me sens maintenant un peu rassuré. En cas de problème ça sonne super fort, ça clignote, et surtout ça alerte directement mes proches. Idéal pour faire fuir les vilaines gens !
