Here’s how to deploy your pepper spray most effectively:

1. Hold the spray in one hand and slide up the safety cap with your thumb.
2. Press firmly with your thumb in the center of the trigger. When you do, all functions activate at the same time.
3. Aim at the attacker’s eyes, then at the nose and mouth.

Please note that even after you release the trigger, the siren and light will continue to sound and flash until you turn them off by using a pointed object to push up the test lever on the side of the spray. This is a safety feature to prevent an attacker from turning off the siren and light.

The Plegium pepper spray features a "stream" spray pattern, which has a good balance between range (reaching up to 15 feet) and accuracy (compared to a cone spray pattern), with low risk of blow-back compared to a gel spray pattern.

You can read more about our pepper spray and it's spray pattern in our pepper spray guide.

To trigger the alarm, press and hold both side buttons for 2 seconds. A green light on the button will blink to indicate the alarm has been activated.

Once activated, your emergency contacts immediately receive a phone call with an automated voice message saying you have triggered an alarm and are in danger.

At the same time, they also receive an SMS with a link to a tracking page (opened in a browser) where they can follow your location live and listen to audio from your phone. The audio stream is saved and can later be used for investigation and evidence purposes.

The alarm button must be connected to your phone via Bluetooth for the alarm to be triggered.

Yes. Starting April 1, 2026, we are moving to a subscription-based model. That means our smart features will only be available through Plegium Plus or Plegium Premium. Features that don't include the app (spray, siren, strobe light) will continue to function without a subscription.

Customers who purchased and registered a device before March 31, 2026—and who have not previously subscribed—will be eligible for a free one-year Plegium Plus subscription. Eligible users will receive this offer starting April 1, 2026.

If you have any questions or need assistance, contact us at contact@plegium.com and include your full name, email, phone number (with country code), and date of purchase or a copy of your receipt.

When you activate your smart defense spray or alarm button, your emergency alerts are also sent directly to a monitoring desk, which in turn contacts the police about your situation and location.

This service is included in your Plegium Premium subscription at no extra cost.
