What battery should be used for electronic door locks?

Fingerprint password locks generally use four 5th alkaline batteries. ..

Generally, it can be used for about one year (depending on the function, power consumption design and usage times, etc.). ). According to the industry standard, the anti-theft fingerprint lock should be equipped with an emergency power interface, which can be externally connected with a 9V laminated battery.

First, the use of mechanical keys.

The fingerprint lock is dead, so you can insert a mechanical key to unlock it. In the case of power failure, the electronic chip can't work normally and can be unlocked with a mechanical key.

Second, use alkaline batteries.

All electronic products often turn off after power failure, that is, they cannot be turned on. In case of power failure. Some fingerprint lock manufacturers' locks are made of alkaline batteries, which is different from household electricity. When the power of the user's fingerprint lock is too low, the fingerprint lock will prompt the user to replace the battery in time until the user replaces the battery or the battery is completely exhausted.

Extended data:

The electronic lock is composed of a single chip microcomputer and corresponding hardware circuits, which can complete the functions of password setting, storage, identification and display, driving the electromagnetic actuator and detecting its driving current value, receiving the alarm signal of the sensor, sending data and so on. The MCU receives the typed code and compares it with the password stored in EEPROM. If the password is correct, it will drive the electromagnetic actuator to unlock.

If the password is incorrect, the operator is allowed to re-enter the password for up to three times; If it is incorrect for three consecutive times, the single chip microcomputer will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the driving current value of the electromagnetic actuator and each unlocking operation as state information to the intelligent monitor, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis for intelligent analysis.
