BH-31B Electronic Door Handle 13.56 MHz Bluetooth Remote PIN Stainless Steel Slim 38mm

Product Overview

The BH-31B remotely managed electronic handle offers multi-method access control for interior and exterior doors in residential and rental properties. With stainless steel construction and a slim 38 mm plate (280x38 mm), this handle is designed for compatibility with most mortise locks, including narrow aluminum doors. It features access via fingerprint, PIN, contactless Mifare card (13.56 MHz), Bluetooth app, and classic key, supporting centralized software management and real-time monitoring through the TT Lock mobile application.

A standout feature of the BH-31B is its ability to remotely issue time-limited or event-restricted PIN codes using the mobile app, which removes the need for physical handover of credentials and simplifies property management. This remote code-sharing capability is particularly valuable for short-term rental apartment operators, as it minimizes guest check-in complexity and operational risks. It is recommended for hospitality, property managers, and bulk installations in modern multi-family or commercial buildings requiring flexible access control.
