fingerprint lock is de?

What should I do if my home fingerprint lock is dead?

Under normal circumstances, the power supply mode of the household fingerprint lock is mainly powered by a dry battery. When we use the household fingerprint lock for a period of time, what should I do if I forget to change the battery for the fingerprint lock and the household fingerprint lock is dead? The fingerprint lock cannot be unlocked without power.

The way of fingerprint lock power supply is mainly to use the No. 5 dry battery to supply power for the fingerprint lock. Under normal circumstances, the power supply of 4 No. 5 batteries can be used normally for more than 8 months; 8 batteries can be used normally for more than 16 months (specifically, function , power consumption design, number of uses, etc. are different). Some also produce fingerprint locks according to industry standards, plus emergency power supply interface, which can be powered by 9V laminated battery.





     

  If the household fingerprint lock is dead, you will be prompted in advance to voice, if you have forgotten to replace the battery, you can go to the supermarket to buy a 9v battery, align the positive and negative poles on the external power supply, (about two seconds) After the power is turned on, the normal fingerprint can be unlocked.

   Household fingerprint locks have emergency power-receiving functions. Look for them, some are in the mechanical keyhole, more are under the lock, some are two contacts, some are USB ports, and some have a battery on the back of the fingerprint lock. The box is opened directly, and the four-section alkaline battery is correctly inserted into the battery case according to the positive and negative poles. When the power is turned on, there is a “drop” sound prompt, and then the fingerprint lock can open the door normally.
