ZKTeco Fingerprint Mortise Lever Lock TL300B

The ZKTeco TL300B is a fingerprint mortise lever lock with Bluetooth mobile management. It combines a semiconductor fingerprint sensor with a touch-oriented electronic access arrangement, offering an alternative to a conventional mechanical lever lock where biometric entry is required. ZKTeco also lists IC-card support, so the credential plan can include supported cards alongside fingerprint use.

The manufacturer describes voice guidance, lockout mode and a reversible design. Voice guidance helps users follow the lock's prompts, while the reversible arrangement matters when matching the lock to the door's opening direction. Bluetooth identifies the model's communication approach; it should not be confused with the Zigbee-based TL300Z or treated as proof of direct Wi-Fi connectivity. The intended mobile-management functions need to be checked against the selected application and lock configuration.

Its zinc-alloy construction and listed front and rear dimensions help assess the hardware footprint on the door. The standard door-thickness range is 38 to 60 mm, but a suitable thickness does not establish that the existing mortise, cut-out and fixing positions will match. User capacity is listed as 100; a separate capacity for every credential type should not be inferred from that overall figure. Select TL300B when its fingerprint and Bluetooth arrangement fit the access requirement, and establish the mechanical fit and supplied components before arranging a replacement or new installation.
