1. Product Overview
Infra Fire Sticker (Buzzer-Only Version) is a self-contained fire penetration detection sticker that instantly triggers a local audible alarm when fire breaches or penetrates the protected surface. Designed for EV battery enclosures, wall panels, electrical cabinets, and confined infrastructure, it provides singular event detection — no false alarms, no AI dependency, and no network connection required.
---
2. Functional Description
Detects heat or flame penetration through sticker substrate (via embedded puncture/thermal displacement sensor array).
Triggers piezo buzzer alarm (≥ 90 dB) upon activation.
Alarm remains continuous until manual reset or power depletion.
One-time-use detection cycle; ideal for quick-response fire alert zones.
