This is a bathroom lock system which not only looks different but is also unique functionally. We have read and heard about various bathroom accidents. You can very well understand the helplessness of the person concerned in such a situation.This is a gadget that would be of real help in those emergency moments.
When installed after connecting to the telephone line this lock needs two inputs. Firstly the length of time the person might be in the bathroom and next an emergency telephone number. The moment the door is closed and locked this Help Lock gets activated. When the given time limit is over and the door is still locked the lock automatically sounds an alarm. If within 30 seconds the alarm is not stopped by pressing the cancel[green] button the door gets unlocked and the emergency number gets dialed. In addition to that, the lock itself sounds a help alarm increasing the possibilities of being heard by someone nearby. This very important lock system has been designed by Haishan Deng and it is truly an awesome thought.
