BH-31B Electronic Handle 92mm Stainless Steel Fingerprint Bluetooth PIN Remote TT Lock

Product Overview

The BH-31B remotely managed electronic handle is a smart lock solution for access-controlled doors, supporting a 92 mm center distance and featuring a slim escutcheon (280x38 mm) made of stainless steel. Designed for residential and rental property use, it enables entry via fingerprint, proximity card, Bluetooth mobile application (TT Lock), or PIN code. The device supports up to 200 fingerprint or card users and 150 PIN users, and is compatible with most market-standard mortise locks due to its adjustable mounting sleeve.

What distinguishes the BH-31B is its multi-modal remote access management via the TT Lock app, which allows owners or administrators to send time-limited or recurring PIN codes and monitor access events in real time. This capability addresses common property management challenges such as key-sharing and access control for short-term rentals or serviced apartments. It is particularly well-suited for property managers, rental operators, and facilities requiring flexible, remote access management across multiple entries.
