19. Fall down alarm
For the elderly who fall and are unable to get back up on their own and this may cause a devastating consequence.
How it works:
The device must sense height, impact and angle etc. The height must above 1 meter, and angle change over 45 degrees. The authorized numbers will be
alerted without the user pushing SOS button when the fall sensor is activated.
Due to the daily life activities (like some sports, sit back on a coach, etc.), sometimes device may detect a fall incorrectly, this situation may cause false alarm.
However, users can manually cancel the fall alert by pressing SOS button during its beeping.
Very Important: Because it still has few chances for the non-detected falling down, we still strongly recommend user to press SOS button when it has
emergency situation.
Command:
FL1,1 or FL1,2 or FL1,3 or FL1,4 or FL1,5 or FL1,6 or FL1,7 or FL1,8 or FL1,9
1 equals most sensitive, 9 equals least sensitive.
