Product overview

The JHEMCU JHE42B Finder buzzer alarm combines audible signaling with LED light for multirotor aircraft. It provides two operating modes: traditional active buzzer functions synchronized with the flight control, and an automatic alarm following main battery power loss. With the flight control normally connected, the unit emits a 110 dB alarm and white LED light after 30 seconds without main battery power. Holding the release button for more than 2 seconds turns off the sound.

Measuring 23*17*17MM and weighing 7.4g, the JHE42B Finder connects to the flight controller’s buzzer interface and supports BF, CF and INAV flight controls. With correct flight control wiring and the aircraft powered on, it charges automatically from the flight control power supply. The red LED lights during charging and turns off when fully charged. A flashing red light indicates that the flight controller is powered off, with a 30-second waiting period. The package contains one JHE42B Finder and one 3P*1.0MM cable.
