Semaphor consists of a bell, a main internal unit and wire

You easily control access to your office or waiting room with the Semaphor. This set contains:

• a bell push button in steel-grey plastic with a black push button;
• a main internal unit in matte black plastic; the desk model has an ornamental strip in anodised aluminium;
• 15 meter of wire.

The bell push button is mounted on the outside of the access door. It is attached directly to the wall with screws. There is no need for a flush-mounting box. Furthermore, you also receive pictograms and text in different languages to hang on the door so that visitors will always perfectly understand your message. In the office, you have an internal unit with four keys right at your fingertips. With these, you send the following light signals to the access door:

• green: the visitor may come in;
• orange: the visitor must wait;
• red: you are not available and the visitor may not enter.

With the N.O. push button with potential-free contacts, you open an electric door lock or you send a buzzing signal to the waiting room. The main internal unit can be expanded with a sub internal unit, which operates in the same way and has the same possibilities. This is handy if you have more than one desk in your office or if you would like to connect an adjacent conference room to your system. The sub internal unit and the extra door bell are always ordered separately. The Semaphor operates at low voltage 12V AC.
