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.

Installation
5.1 Connecting the Parachute system to the
Drone
1Connect the mounting
bracket to the forward upper
part of the drone, by screwing
the four thumb screws
2Position the parachute system
on the mounting bracket, the
SAP should be face the rear of
the drone
3Attach the four screws, four
spring washers and four
washers in this order. Tightly
secure the screws using the
small Allen key. The parachute
cable should be inserted
through the carbon plate as
indicated in the photo

SafeAir™ M-300 Pro Installation Guide 10 www.parazero.com
5.2 Connecting the electronic TerminateAir
1The first stage is to replace the
original battery locker with the
TerminateAir locker. Position
the battery locker in the locked
position, while the batteries are
not installed. Use adhesive
tape to prevent the remaining
parts from popping out during
the process
2Use the provided large Allen
key to unscrew and remove
the battery locker. Keep the
battery locker and its parts in a
safe location
3Screw the TerminateAir locker
until secured and remove the
adhesive tape

SafeAir™ M-300 Pro Installation Guide 11 www.parazero.com
4Turn the TerminateAir locker
into its unlocked position and
slide the 2 TerminateAir parts all
the way in the battery
compartment, until the
connector is attached
5Use the long black cable to
connect between the 2 lower
ports of the 2 electronic
TerminateAir units. Notice that
the white line on the
connector and on the port
should match
6Use the short black cable to
connect between the upper
port of the left electronic
TerminateAir unit and the FTS
port of the SAP. Notice that the
white line on the connector
and on the port should match
7Install the drone’s batteries
and lock the TerminateAir
locker. Use the TerminateAir
locker exactly as the previous
battery locker to remove or
reinstall the batteries
8For storage purposes, bend the
TerminateAir locker
downwards while in locked
position, be aware that it could
only be bent to one position,
rotate it by 180 degrees if
necessary

SafeAir™ M-300 Pro Installation Guide 12 www.parazero.com
5.3 Flight Preparations
1The SAP should be charged using the provided USB-C cable for at least 3 hours before
the first flight. The SAP is automatically charged during flight. If the system is not used often,
it should be charged before flight for 3 hours.
Charge the SAP when the safety pin is all the way in.
2(Optional) Charge the RC using the provided USB cable for at least one hour before first
use. Charging should be made while the RC is turned off.
Caution
When the RC is turned off or there is no link between the RC and the receiver, manual
triggering is not available
3Using the desktop application allows for firmware update; automatic download of flight
logs and system configuration. Disconnect the FTS cable and the parachute cable from
the SAP, Take out the safety pin all way and connect the SAP to your computer using the
provided USB-C cable. The desktop application installation and use instructions may be
found here. Use the pyro-dummy connected instead of the parachute cable for the SAP
to complete initialization.
Warning
Please disconnect FTS and Parachute cables from the SmartAir to prevent activation during
firmware update process

SafeAir™ M-300 Pro Installation Guide 13 www.parazero.com
5.4 Inserting the Pyro actuator
Caution
During all installation stages, be sure –
That the safety pin remains in its proper place.
Not to connect the parachute cable to the SmartAir.
1Unscrew the safety transportation capsule and take out the pyro-actuator - when taking
out the pyro-actuator from the transport capsule you are obliged to use protective
glasses.
2Insert the pyro-actuator into the socket in the bottom of the container, make sure you
push it all the way in.

SafeAir™ M-300 Pro Installation Guide 14 www.parazero.com
5.5 Inserting the parachute
1Hold the folded parachute,
remove the rubber bands
while applying pressure to the
upper yellow cap and the
bottom red base. Insert the
folded parachute into the
Canister so the red base inserts
first. Push the parachute in all
the way. Remove the yellow
cap and Squeeze the
parachute itself into the
canister while removing the
paper container out (keep the
paper container in a safe
place for repack purposes
2Do not remove your hand from
the top of the parachute. With
your other hand, leave the
parachute main strap, with the
carabiner attached to it
outside of the canister, facing
the SAP. Place the yellow cap,
make sure the cap is secured
and that the parachute is not
sticking out of the cap
3Secure the carabiner into
place by using the provided
rubber band
4Connect the four parachute
strings to the base of each
drone arms, by wrapping the
string around the arm and
inserting one end into the
string’s loop and tightening it

SafeAir™ M-300 Pro Installation Guide 15 www.parazero.com
5Insert each loop to the
carabiner of the parachute
and secure the carabiner
6Secure each parachute string
to its designated conduit on
the electronic TerminateAir.
The strings shouldn’t obstruct
the sensors nor the propellers.
The strings should climb in a
straight line from the conduit
and upwards

Operating Guidelines
8.1 Preflight
Initial Conditions: The safety pin is in.
Finalize all the preflight procedures to your drone and payload. The following tasks are in
addition to the regular preflight tasks –
Ensure that the thumb screws and the mounting legs screws are firmly closed.
Connect the parachute cable to the SAP and store the pyro dummy. Notice that the
white line on the connector should face upwards.
Verify that the electronic TerminateAir cables are connected (the short and the long
black cables).
Make sure that the rotors may spin freely without any existing or potential contact with
the parachute system and that the cables and strings do not obstruct any sensor.
Carefully remove the safety pin, then turn on the RC (optional). At the end of the
initialization process, the SmartAir LED should be BLUE and the RC LED should be green.
Turn on the power to the drone and verify that the electronic TerminateAir LEDs are on
Go back to a safety distance of at least 5 meters
8.2 Takeoff
When climbing, you must climb to approximately 7 meters before the system is armed.
Climb until you hear a single long beep, and the LED is GREEN.
The system is now armed and ready for activation in case of an emergency.
8.3 Before Landing
When approaching landing, and the drone slowly while keeping it level. Three seconds after
the rotors are stopped on the ground, the parachute system automatically disarms. At that
point, a long double-beep is heard and the LED is BLUE.
8.4 After Landing
Place the safety pin inside the canister and (optional) turn off the RC.
Disconnect the parachute cable from the SAP and connect the pyro dummy.
Warning
Do not move the drone or system while the system is armed (green LED). An angle breach
may cause the system to deploy. The parachute and cover will be projected at high
speed and may cause injuries. Inserting the safety pin all the way in will prevent this risk.
Caution
Flight in Sport Mode is not allowed
Caution
Rough maneuvers in close proximity to the ground might result in parachute
deployment.
