Today´s topic of INDUSTRONIC functions is Call Request Control. This function is often used at gateways and entrance areas. There, visitors must make a call request to the central control room via a gate intercom station.
Control Rooms – Flexible and Always Available
This call request reaches several control room intercom stations simultaneously. Depending on the situation, operators in the control room can flexibly decide at which intercom station they want to accept the call request and conduct the conversation. At the same time, the other stations are free and can accept further calls.
Communication is controlled by the Control Room
After the call has been accepted by the control room, a voice connection is established and controlled by the control room. During the course of the conversation the person at the entrance does not have to press any key again.
Communication Procedure
The following illustration shows the communication procedure in general.
Gate Intercom Stations with only 1 Key
