The problem when the external intercom panel of an apartment building does not have the function of opening the door using a code combination is easily solved:

- in addition to the intercom, an eüra code panel is installed, working together with the TTLock app & Web console.

The code panel is connected to the existing electric lock of the front door, therefore:

• People using the intercom will continue to open the front door as before;

• Owners who rent out their apartments for short-term rentals will provide their guests with a unique access code to the front door.

Each guest can create a unique code or make one permanent access code of 4 - 9 digits.

An unlimited number of apartment owners can have access to the TTLock app & Web console administration.

Technical information:

1. The existing electric lock must operate under DC 12 - 24V;

2. If the existing electric lock is an NC (normally closed) type, then you need to connect it via a code panel to an additional power supply. Installation and connection work must be carried out by a qualified electrician;

3. The TTLock app & Web console code panels work in conjunction with WiFi gateway eüra ACA-20C9 and requires an Internet connection;
   

4. Read about the method of organizing a local WiFi Internet point and the connection diagram to a buffer power supply in a separate blog.
