TFS-Dialog 400

Elegantly designed door intercom system for maximum operating comfort

Take an ultra-flat, uninterrupted glass front with sensor keys, install the speaker and microphone well protected and invisible behind it and adorn it with wraparound LEDs for indirect ambient lighting – and what have you got? The new door intercom system TFS-Dialog 400 boasts an exceptionally elegant appearance and an unusually large range of functions.

 

Made for an analogue extension input of your telephone system

TFS-Dialog 400 can be connected to an a/b port of any ICT system – whether it’s from Auerswald or any other manufacturer. But it also gets along perfectly with an AVM Fritz!Box or an Alcatel/Avaya/Unify system in a business environment. When connecting it to an Auerswald ICT system, however, you’ll benefit from a template which greatly simplifies getting started.

Coding is done by an app

Phone numbers, functions or the freely selectable number of call buttons – everything can be coded conveniently and quickly via smartphone app (Android and iOS). These settings are simply transferred to the door terminal – to be stored or changed as needed.

A sensor field replaces mechanical keys

The illuminated sensor field with its energy-saving LED technology is clearly perceptible by day or night. In summer or winter, in the wet and in the dry, with gloves or a bare finger, the sensor field reliably indicates any "key pressed".

Lock with numerical code

Deactivate the alert system or open the door conveniently without a key – simply by entering a 4 to 8-digit code via the numeric field superimposed on the sensor field. This "code lock" can be used parallel to the door bell function or separately.

Indirect, discreet ambient lighting

The indirect wraparound ambient lighting uses white LEDs to emit all light to the rear; all it takes is an additional bell transformer. Once that’s installed, you may as well use further functions, such as e.g. a door opener.

Intelligent “door open” detection

Via a contact at the door (not included in the scope of delivery), the door terminal will be able to detect if the door has been opened upon pressing a bell button. In that case, the phone will immediately stop ringing.

Adaptable to loud environments

No matter if the door terminal is installed next to a busy road or in a tranquil environment – the TFS-Dialog 400 lets you choose between two sensitivity levels for loud or quiet environments.

Additional switching contacts

The call station offers three additional relay contacts which may be used e.g. to control a door opener, the light in the hallway or to connect an additional door bell – provided there is a bell transformer.

Do more “tricks” with an a/b switch module

If you want to activate further functions aside from the bell ringing, an optional a/b switch module from Auerswald will pay off immediately – to turn on the light in the hallway or to control the door bell. Are you talking to a einem visitor at your door? Simply hit the number key for the door opener!

Ultra-flat and correspondingly discreet

Designed for surface-mounted installation, the TFS-Dialog 400 surprises with an unusually flat design: despite its 6 mm strong safety glass which is immune to breakage and scratches, this door intercom system is only 28 mm deep altogether.

a/b Switching Module

Exclusive by Auerswald: the a/b switching module

If pressing the bell button is supposed to activate other functions as well, an a/b switching module pays off immediately: it takes care that e.g. the light in the hallway goes on or the existing door bell rings. The modules are simply interconnected at any point of the signal line between door intercom and the analogue (a/b) port of your telephone system.

When the bell button is pressed, a special control signal triggers the desired switching process. If e.g. you are talking to the visitor at your front door, you can release the door opener by pressing a key on your phone. And if you install several a/b switching modules, you can control various switching processes with different frequencies.

 

Communication and switching using the mobile phone

Assuming you are out of the house for an errand. If the door call is forwarded to your mobile phone you can inform the person in front of the door that you will be back in a second. Or you can tell the postman where to leave the parcel. If it is a family member who has forgotten the key you can open the door with your mobile phone, switch on the light or activate other switching tasks via the connected a/b Switching Modules.
