With outstanding security and convenience, fingerprint door locks have become the top choice for many consumers. However, one of the common questions that many people wonder is: “Can the fingerprint door open after a power outage??” In the article below, OSUNO will help you answer this question in detail and provide optimal solutions to ensure that your home is always safe in all situations.
Operating principle of fingerprint door lock
Before delving into the answer to the question “Can a fingerprint door open after a power outage?”, let’s learn about the operating principle of a fingerprint door. Fingerprint door lock Works based on user fingerprint recognition to open the door. Each fingerprint is unique, so only those who have been authorized can open the door. This helps prevent the risk of bad guys counterfeiting keys or detecting codes to gain entry.
Currently, most fingerprint door locks use batteries as the main power source. Common types of batteries commonly used are AA batteries or lithium batteries, with a lifespan ranging from 6 months to 1 year, depending on usage. Some lock models such as OSN-3302, use backup batteries, with up to 8 batteries, but when operating, only 4 batteries are needed, and when these 4 batteries run out, the lock will automatically switch to using the remaining 4 batteries.
In addition, many types of locks also integrate smart features such as low battery warnings, user memory, and the ability to connect to smart home systems.
As for access controls, they operate on electricity but use a power source completely separate from home electricity. This power source is a separate linear source, with a voltage of only 12V, ensuring safety and not causing the risk of fire or explosion. In the event of a power outage, the system will have a backup power source that operates for a short time to ensure no problems occur when emergency access is needed.
Can a fingerprint door open without power? How to handle power outages?
One of the biggest concerns users have when using fingerprint door locks is that the lock may not work during a power outage. This is completely understandable, because most electronic devices depend on power to operate. However, fingerprint door lock manufacturers have taken this problem into account and integrated many backup solutions to ensure that fingerprint doors can still operate normally even during a power outage.
Open the door with the mechanical key
Although fingerprint locks are modern and advanced, the manufacturer still does not ignore the traditional mechanical key feature. In case the lock completely loses power, you can still use the mechanical key to open the door. This is a simple yet effective solution that ensures that you are never stuck outside.
Mechanical keys are often designed to be hidden on the back or underneath the lock’s cover, helping to ensure higher aesthetics and security.
Use the emergency charging port
One of the other smart features that many high-end fingerprint locks today are equipped with is an emergency charging port. When the battery is completely exhausted or there is a power outage, you can use a power bank or other temporary power source to supply power to the lock. This charging port is usually a micro USB or USB-C port, allowing you to easily connect to today’s popular charging devices.
After connecting to the power source, you can unlock with fingerprint as usual. This is a quick and effective solution in case of a sudden power outage.
Backup battery to open the door
As mentioned above, most modern fingerprint door locks use AA batteries or long-life lithium batteries. Typically, this battery can keep the lock operating for about 6 to 12 months, depending on frequency of use. When the battery is about to run out, the lock will send a warning via LED light or sound so the user can promptly replace the battery.
If the battery is completely discharged and you don’t have time to replace it, don’t worry! Many fingerprint locks are equipped with an external USB charging port, allowing you to connect a backup battery or temporary power source to power and unlock.
Summary
So, can the fingerprint door open without power? The answer is yes, with convenient backup solutions, you can be completely assured that your fingerprint door will still work well in all situations even when there is a power outage. Don’t forget to periodically monitor and maintain your door locks to ensure maximum safety for your home.
