Abstract: An intercom system for emergency rescue has a user extension, an administration server and a management device. The user extension has a serial number and is capable of generating an alarm signal by operation. The administration server connects to the user extension and the management device to receive the alarm signal. A plot plan recording a location of the user extension is stored in the administration server. The administration server transmits the plot plan with the location of the user extension that outputs the alarm signal to the management device to display. Therefore, an administrator equipped with the management device communicates with the user extension via a video connection established by the administration server. With the help of the plot plan and the video connection, the administrator provides timely assistance to reduce casualties.
