Overview
The MSA DragonFly 10000000894 is a stand-alone Personal Alert Safety System (PASS) designed for firefighters and first responders working in hazardous environments. This motion-sensitive device automatically detects when a user becomes immobile and activates an audible alarm to alert rescue personnel. The pre-alarm chirps if user motion is not detected for 18 seconds, providing early warning before the full alarm activates.
Key Features
- Automatic activation through a tethered key system that can be attached to jump seat, locker, or vehicle interior; when user jumps to action, key instantly snaps off and activates device
- Patented Gyro-Trac motion sensor guards against false alarms using a flexible printed circuit board and non-corrosive electrically conductive phosphor bronze ball bearing
- Easily accessible reset button and manual activation button in front of alarm module
- Multi-stage alarm progression with pre-alarm warnings before full activation
- Designed for modular maintenance and field replacement of components
