The 2n1 Personal & Burglar Alarm generates 120 decibels—volume comparable to chainsaw operation. This output level penetrates walls and reaches distances exceeding visual recognition range. Attention attraction serves defensive purposes beyond direct force.
Dual-mode functionality adapts to different security scenarios. Personal mode attaches to keychain or bag for mobile carry. Door mode hangs on doorknobs to detect entry attempts. The versatility addresses both mobile and fixed security applications.
Pull-pin activation provides stress-proof operation. Complex sequences fail under panic. Simple mechanical pull requires gross motor control that persists during high-stress responses. The pin detaches through deliberate pull. Alarm activation occurs immediately.
