Product information

Description

Avatto SDL-S1-B90 digital lock cylinder (90 mm, black) is an electronic biometric door cylinder designed to replace a standard mechanical cylinder and provide multiple convenient access methods while maintaining standard cylinder dimensions. The device supports fingerprint recognition, IC card entry, remote control via the Tuya mobile app and a traditional mechanical key for emergency use. Its adjustable length and simple installation make it suitable for most residential and commercial doors.

Advantages

The cylinder offers four unlocking methods—fingerprint, IC card, Tuya app and mechanical key—providing flexibility for different users. Fast fingerprint recognition (0.3 s), low power consumption with CR123A battery supply and a low-battery alert improve day-to-day reliability. Bluetooth Low Energy connectivity enables app-based access control and viewing unlock history. The cylinder is made from durable materials, supports 360-degree fingerprint scanning and includes waterproof protection and a USB charging port for emergency power.

How to use

Install the Avatto SDL-S1-B90 cylinder using a hex screwdriver; installation typically takes about 10 minutes and does not require altering the door or frame structure. Adjust the cylinder length as needed to fit the door. Enroll fingerprints and register IC cards through the device interface or the Tuya app, and add users via the app for remote access control. Use the mechanical key only as an emergency measure.

Usage recommendations

Ensure the battery is a fresh CR123A alkaline cell and monitor the low-battery alert to avoid service interruption. Regularly back up access settings and review the unlock history in the Tuya app. For outdoor installations, verify the door hardware provides adequate protection from direct water exposure despite the cylinder’s waterproof rating. Follow the manufacturer’s instructions for fingerprint enrollment and cleaning to maintain reliable recognition.
