General information
1.1 Introduction
Caution
During all installation stages, be sure –
Not to connect the batteries to the drone.
Not to connect the TerminateAir to the SmartAir.
The ParaZero SafeAir M-300 Pro is smart-parachute system that deploys autonomously after
detecting a critical failure in your drone. The parachute slows the descent rate of your drone
and reduces the kinetic energy upon impact. The system incorporates the following main
components:
1A unique patented ballistic parachute deployment system for near-zero-time
deployment, designed for operation at very low altitudes, even at zero speed.
2A completely autonomous identification and activation capability, using its dedicated
SmartAir™ Pro Autonomous Trigger System.
3A DJI M300 dedicated, independent flight termination system, called TerminateAir™. The
M300 TerminateAir™ controls the power supply of the drone for emergency shutdown.
The system is designed for fast assembly and detachment, using only four tool-free screws.
The SafeAir™ M-300 Pro drone safety system incorporates the following features:
1Deployment in a fraction of a second.
2Independent, autonomous detection of critical failures in an M300 drone, including XYZ
acceleration, critical angles and extreme maneuvers.
3Weather detectors.
4Effectiveness at low altitudes and zero speed.
5Effectiveness at extreme roll angles and at maximum speed.
6Audio and visual warnings.
7Easy, user-friendly Installation.
8Access data logs via the desktop application.
