Simply pull the pin and Lyra activates instantly — emitting a 130 decibel siren and a blinding LED strobe light simultaneously. To deactivate it just reinsert the pin. That's it. No buttons to fumble with, no app required, no complicated setup. In a stressful situation simple is everything.

Louder than you think. 130 decibels is the threshold at which sound becomes physically painful to be near — comparable to a jet engine at close range. It's loud enough to be heard from streets away, loud enough to disorient anyone nearby and loud enough to attract immediate attention from people around you. It doesn't just alert — it stops situations before they escalate.

Absolutely — personal safety alarms are completely legal everywhere in the UK, Australia, Canada, Ireland, New Zealand and internationally. Unlike pepper spray which is illegal in the UK, Australia and New Zealand, a personal alarm is one of the only fully legal personal defence tools available anywhere in the world. You can carry it everywhere — on public transport, in schools, at work, on flights and abroad.

No personal safety device can guarantee any outcome in every situation — and anyone who tells you otherwise isn't being honest with you. What we can tell you is this: a 130 decibel siren activating without warning is an extremely powerful deterrent. It draws immediate attention from everyone nearby, it disorients the person closest to it and it signals instantly that this situation is no longer quiet or unwitnessed. Most opportunistic incidents rely on isolation and silence — Lyra removes both in an instant. It won't stop every situation but it changes the odds significantly and that's exactly what it's designed to do.

Lyra's battery lasts for over 1 hour of continuous activation — more than enough for any emergency situation. For everyday carry the battery will last months without needing replacement. When it does need charging Lyra uses a standard USB-C cable — the same one you likely already use for your phone — so you're never hunting for an obscure charger. We recommend giving it a quick charge every few months and testing it briefly to make sure it's always ready when you need it.

Lyra comes with a built in keyring attachment — simply clip it onto your keys, bag strap, gym kit, backpack or wherever works best for you. The whole point is that it's always within reach. Most people attach it to their keys so it's impossible to forget.

The pin needs to be deliberately pulled to activate — it won't go off from being knocked around in your bag or from normal movement. The design specifically prevents accidental activation while still being fast and simple to use when you actually need it.

Anyone who wants to feel safer. Lyra is used by women walking alone, students heading home late, runners and cyclists, commuters, travellers and people who work night shifts. It's also bought as a gift by parents, partners and friends who want the people they love to feel protected. If you've ever felt vulnerable out alone — Lyra is for you.
