MARIUPOL v2.3
Initiator
Used in fixed-wing UAVs and designed to activate the charge by sending a pulse to the electronic detonator. Activation is inertial (upon impact) using an accelerometer or manually triggered via the PWM channel. There is also ARM/DISARM from the remote control via the PWM channel.

Technical features
Timings
The 3-hour self-destruct timer is designed for long fixed-wing-type UAVs. The safety timer has also been increased, as preparing for takeoff with “wings” involves more nuances than with copters.
Backup power supply
The initiator has a built-in CR123A 3V power supply, but it can also be powered via a +5V contact. In this case, the battery will not discharge and will serve as a backup power supply.
PWM connection check
When turned on, the initiator will check for the presence of a DISARM PWM signal (1000 µs) from the flight controller, and if it is not present, it will report a malfunction.
550 mm cable
The cable with a three-pin connector is suitable for most wing controllers, and its length allows the initiator to be placed at any point on the drone.
Quick-release terminal block
A terminal block that allows you to prepare connections to the ED in advance and has a vertical placement - the design of the fixed-wing-type UAV was also taken into account.
Button placement
We moved the on/off button to the front panel, taking into account the nuances of placement in the “wing” housing, namely, the lack of access to the sides of the initiator.
4 protection levels
Self-diagnosis
When the device is turned on, a self-diagnostic test is performed. The device checks: accelerometer data, presence of a fuse, battery charge level, presence of a PWM signal, and absence of a PWM signal at the “SERVO” input.
Mechanical fuse
After removing the fuse, a 4-minute safety timer starts counting down.
If the fuse is inserted into the starting position, after four short beeps, the device is deactivated and the safety timer is reset.
Safety timer
During the safety timer, the device does not respond to overloads (impacts) and FIRE initiation commands (1500 μs) from the remote control.
Electronic fuse
The last level of protection is ARM/DISARM from the remote control via the PWM channel. After receiving the ARM signal (1000 μs), the device will start responding to overload and the detonation command from the remote control.
