1. Main advantages of the ACS TT A820 lock
- High security: the lock is equipped with a “Pickproof” mechanism, which is resistant to picking and unauthorized manipulation.
- Warning alarm system: an integrated alarm will warn of an attempt to forcefully break into the cabinet, as well as a low battery level (when the voltage drops below 3.8 V).
- Long battery life: the lock will operate for approximately one year on 3 pieces of AA alkaline batteries under normal use.
- Emergency power supply: if the batteries are completely discharged, the lock can be powered externally via the USB-C port, which will prevent access from being blocked.
- Universal installation: it is suitable for a wide range of furniture – from drawers to single- and double-leaf cabinets, with both wooden (9-22 mm) and metal (0-9 mm) doors.
2. Opening methods
The lock offers maximum flexibility thanks to different unlocking methods:
– Mobile application (TTLock / Tuya): control directly from a smartphone via Bluetooth.
– Password: entering a numeric code on the touch keyboard.
– RFID card: support for M1 type cards with a reading distance of up to 20 mm.
– NFC function: possibility of unlocking using a smartphone with NFC or Apple Watch.
3. TTLock function and its advantages
The TTLock application is an advanced access management tool that turns the lock into a fully professional solution:
- Remote key management and distribution: you can generate and send digital keys to users even when you are not at the lock (remote unlocking is also possible when using a gateway).
- Real-time access logs: the application stores history, so you can see exactly who unlocked the lock and at what time.
- Larger capacity: the version with TTLock supports up to 250 passwords and 1000 cards, which is significantly more than the standard version without the application.
- Easy programming: all settings, such as adding cards or codes, are intuitively done in the application.
4. Where is the lock best used and why?
The lock has two operating modes that define its best use:
Use: fitness centers, swimming pools, shared offices (coworking).
Why: In this mode, the lock resets for the next user after unlocking. There is also a Timer Auto-unlock function (optional), which automatically unlocks the lock after a certain time (1-24 h), thus preventing long-term blocking of the lockers.
Use: office containers, private employee lockers, home furniture.
Why: the lock is permanently assigned to a specific user, which guarantees personal security for stored items.
