The HellGate FPV Buzzer DUO is a fully automatic acoustic alarm for your miniquad or any other kind of aircraft that could suffer from battery ejection after a crash. With the HellGate Buzzer you don’t have to be afraid anymore. After the main battery is accidentally disconnected, it will activate the alarm state and after one minute, if the battery is not reconnected it will start beeping. The acoustic alarm will last for more than 3 days. I can also switch itself automatically into “eco” mode (after 3 days of active alarm) and continue to beep every 30 seconds for more than 2 weeks.
There is no complicated installation or maintenance  process involved. Simply connect it to a 5V power input, common Ground and a FC buzzer Ground if you would like to use it as a regular buzzer on your aircraft, since it supports a buzzer passthrough. It also has an PWM pad so it can be controlled wit h a direct connection from receiver.
To deactivate the buzzer (when you don’t want to fly immediately after disconnecting the empty battery or for transport)  you simply connect the battery for a a short amount of time and disconnect it right after. (just touch the plugs for 0.5s to 2s and it will disarm) The buzzer will respond with an appropriate deactivation tone.
