A personal safety alarm is a small device, usually on a keychain, that makes a very loud siren when you pull a pin or press a button. Many also flash a light. Its job is to draw attention to you quickly. A standard alarm does not call anyone; a connected model can signal your phone to call for help.
This guide explains how personal alarms work, what they can and cannot do, and how to choose one in Pakistan. Ziva and Ziva+ are our own alarms, so we will also be clear about where they fit and where they do not.
What is a personal safety alarm?
Personal safety alarm: a small handheld device that sounds a loud siren, often with a flashing light, when you activate it. It is designed to draw attention quickly. It needs no aim and no contact, and a standard model needs no phone.
You may also see them called personal alarms, safety keychain alarms or SOS keychains. Most are small enough to clip to your keys, a handbag strap or a backpack, so they stay within reach.
How does a personal safety alarm work?
Pull-pin alarms and button alarms
Most alarms start in one of two ways. A pull-pin alarm sounds when you pull a small pin out of its body. A button alarm sounds when you press, or press and hold, a button. Forbes Health notes that pull-pin alarms are more common than button-activated ones.
A pull-pin design has one practical advantage. If the pin stays attached to your keyring, pulling the alarm away from your keys starts it. You do not have to find a small button first.
The siren and the flashing light
The siren is the main feature. Alarms sold in Pakistan are commonly rated between 120 and 140 decibels (dB). For comparison, a busy street is about 80 dB, according to Nationwide Children's Hospital. Many alarms also flash a light, so people nearby can see where the sound is coming from.
Ziva is rated at 130 dB, about as loud as a fighter jet passing 100 feet overhead, and flashes a light when the pin is pulled. It also has a separate button that turns on a small LED light without the siren, which is handy at a dark gate or on a staircase.
How to stop it
On a pull-pin alarm, push the pin back in until it is fully seated. The siren stops and the alarm is ready for next time. Button alarms usually stop with another press, so check the manual for yours.
What a personal alarm can and cannot do
| A personal alarm can | A personal alarm cannot |
|---|---|
| Draw attention to you with sound and light | Guarantee that someone hears it or comes to help |
| Work with no phone, internet or setup (standard models) | Call or message anyone by itself |
| Light up a dark path, if it has a light | Replace calling 15 for police or 1122 for rescue |
| Give you a moment to move towards people or a lit place | Help much if it sits at the bottom of a zipped bag |
We think this honesty matters. An alarm is one useful tool, alongside your phone, the people around you and emergency services. It is not a promise of protection, so be careful with any product that claims to be one.
Who carries a personal alarm in Pakistan?
People carry alarms for everyday moments:
- University students walking between classes, to the hostel or to the university van.
- Commuters using ride-hailing apps, rickshaws, buses or office vans.
- Working women on late shifts, or walking to a parked car.
- Travellers finding their way around a new city or airport.
- Men on evening walks or runs, and families buying one for an elderly parent.
Women are the main users, but nothing about an alarm is women-only. Parents, brothers and husbands often buy them as gifts, too.
Standard alarms vs connected SOS alarms
A standard alarm makes sound and light. That is all it does, and its simplicity is its strength: nothing to set up and nothing to pair.
A connected alarm also pairs with your phone over Bluetooth. When you activate it, it signals your phone, and your phone can then call for help or alert your emergency contacts, depending on its settings.
Two points are worth knowing. The alarm itself does not call or text anyone; your phone does. And what happens next depends on your phone, its settings, your SIM and your network.
Ziva is our standard alarm and Ziva+ is our connected model. For Ziva+, we recommend the Ziva Safe app for iPhone and Android: about five seconds after you pull the pin, Ziva+ alerts the app, which can call emergency services, share your location by SMS with the emergency contacts you added, or both. Without the app, Ziva+ can trigger your phone's built-in Emergency SOS instead, which may not send your location to your emergency contacts, especially on iPhone. Our Ziva+ setup guide walks you through it. If you are deciding between the two, see Ziva vs Ziva+.
Rechargeable vs battery-cell alarms
Many low-cost alarms run on small button cells, often LR44 batteries. They work, but the cells need replacing, and it is easy to forget until the alarm sounds weak.
Rechargeable alarms charge by cable instead. Ziva and Ziva+ have a built-in battery that charges by USB-C in about an hour. They are rated for up to 90 minutes of alarm use, and in our own test Ziva ran for more than 60 minutes. The trade-off is that you need to remember to charge it. A monthly test-and-charge habit takes care of that, and our safety guide shows how.
How to choose a personal alarm: the Reach, Pull, Reset check
Before you buy any alarm, ours or anyone else's, ask three questions:
- Reach: Can you reach it within 3 seconds where you normally carry it? If it lives at the bottom of your bag, the answer is no.
- Pull: Can you start it with one hand, without looking?
- Reset: Can you stop it easily, and keep it powered?
Then check three more things:
- The loudness rating, and whether the seller says at what distance it was measured.
- A light, if you often walk in dim places.
- Local support: delivery, returns and a warranty you can actually use.
For reference, Ziva Safe offers free delivery across Pakistan, Cash on Delivery, 7-day returns and a 6-month replacement warranty for device faults (see our refund and warranty policy).

Frequently asked questions
Does a personal safety alarm need a phone or the internet?
No. A standard alarm like Ziva works on its own: pull the pin and it sounds. Connected models such as Ziva+ also use Bluetooth to signal your phone, through the Ziva Safe app (recommended) or the phone's built-in Emergency SOS. What the phone does then depends on its settings, SIM and network.
How loud is a personal safety alarm?
Alarms sold in Pakistan are commonly rated between 120 and 140 dB. Ziva is rated at 130 dB. Ratings are usually measured close to the device, so the sound is quieter further away.
How do I turn a personal alarm off?
On a pull-pin alarm, push the pin back in until it is fully seated. The siren stops and the alarm resets for next time. Button alarms usually stop with another press; check the manual.
Can a personal alarm go off by accident in my bag?
It can if the pin is pulled loose, so make sure the pin sits firmly and the alarm hangs where it will not snag. If it does go off, push the pin back in.
Is a personal alarm a weapon?
No. It makes sound and light and needs no contact with anyone. It is not a spray or a stun device.
How often should I test my alarm?
Once a month. Warn people nearby, hold it at arm's length away from your ears, pull the pin for one to two seconds, then push it back in.
