In case of a threatening situation – confrontational, aggressive behaviour or physical harm – the employee sets off a silent call via the discreetly placed call button. Feedback will be immediately available via an LED on the call button:
- A) No LED: Resting state.
- B) Red LED: Sending the call from the radio button.
- C) Green LED: Call is successfully transmitted.
Server
The server can be considered as control center of the
overall system.
Physically, it is a conventional, LAN-based MS Windows
Personal computer on which a special component
(the „Silent Radio Call“-Server) is installed and
can be executed.
Gateway
The Gateway provides a link between Call Button,
Server and Radio-Displays.
It routes the call from a Call Button to the Radio-
Displays and sends corresponding conformations
back, in order to give a feedback for the affected persons.
One Gateway can support a large number of Radio- Displays and Call Buttons inside of its radio range.
Radio-Display
The radio display receives the forwarded notification from the gateway.
Features & elements of the radio displays:
- - Display at the Room ID
- - Display the radio calls
- - Acoustic signal
- - LED display
- - Confirmation button
In the two-sided version the display additionally shows e.g. the employees name.
