Clearly not for acrobats, clowns, jugglers or mimes, it’s the explosion and drip-proof type rollover sensor transmitter EXH-TKB1…
The EXH-TKB1 is featured to detect human falling, in addition to explosion-proof capability. The transmitter sends radio to the alarm set in the office, when a certain period of preset time has passed after the person wearing the transmitter on his waist belt falls down due to some kind of accident. The alarm sets off loud sound to make the emergency known to people around.
