Richter Czech DH. S3B. RP

The Richter Czech DH.S3B.RP digital door handle is a modern security solution for interior doors. It offers several unlocking methods, including fingerprint, mobile app, IC card, or a numerical code. This makes it suitable for homes and areas with frequent footfall. Access is managed via the TTLock mobile app, where you can set time windows for entry for individual users. The handle supports Apple Home and Google Home smart home systems.

Four Unlocking Methods and User Management

The handle offers four different authentication methods, providing flexibility. You can unlock the door using the biometric fingerprint scanner, a contactless IC card, by entering a numerical code on the touch keypad, or remotely via Bluetooth in the TTLock mobile app. The device's memory is designed for a large number of users. It can store up to 200 fingerprints, 200 IC cards, and 150 unique numerical codes. This makes the hardware suitable not only for homes but also for other areas with frequent footfall.

Advanced Access Management via the App

All handle settings and management are done in the TTLock mobile app, which is available for both Android and iOS systems. The app allows you to track the history of all access events, so you always have an overview of who opened the door and when. The handle also supports privacy mode and passage mode. For full remote control, such as unlocking from anywhere in the world, a separate Wi-Fi Gateway must be purchased.

Durable Design and Backup Solutions

The hardware is made from a combination of aluminium alloy, stainless steel, and hardened plastic, which contributes to its durability in everyday use. The IP55 rating protects the device against dust ingress and water jets, so it can easily withstand normal operating conditions. The operating temperature ranges from -25°C to +60°C. In case the batteries run out, there are two emergency opening options. You can use the included mechanical keys or temporarily connect an external power source via the USB-C connector.
