Features & Specifications

The PRS-M4EX has been designed to easily integrate with the DJI Matrice 4 Enterprise and DJI Matrice 4 Thermal. The PRS mounting holes and screws secure the PRS-M4EX without interfering with onboard sensors. The system includes an integrated EM to power the PRS. The FTS is initiated when either the pilot instigates a deployment through the MTD or when the ATS, using the onboard sensors located in the EM, determines that the Drone has breached the safe flying parameters. Once the FTS is initiated and stops the motors from spinning, the Parachute Pod™ is deployed and will result in the Drone descending under an inflated parachute.

Features

Mounting Bracket	The custom base of the PRS-M4EX has an integrated mounting bracket that allows the PRS to be easily installed with minimal effort.
Independent Power Source	The PRS-M4EX is equipped with an independent power source that allows the system to deploy if the Drone loses power.
Automatic Triggering System (ATS)	The ATS automatically detects failures and triggers the parachute release.
Manual Triggering Device (MTD)	The MTD can initiate deployment of the parachute recovery system at the discretion of the remote pilot in command.
Flight Termination System (FTS)	The plug-and-play FTS stops power to the motors in the event of a failure and reduces the likelihood of entanglement in the Drone's propellers.
Geofence Trigger Method (GTM)	The GTM automatically detects breaches in the user-defined geofence and triggers the FTS and parachute release.
Flight Data Logging	Flight data logging to a dedicated internal storage device that is integrated in the PRS-M4EX.
