A Reassuring Solution
The 4200 Series Audio Rescue Assistance System is an extension of the time proven Cornell 4100 Rescue Assistance System that has received wide industry acceptance. The 4200 includes voice communication which is initiated by simply depressing the call station button transmitting the signal to a central annunicator panel. A single pulse tone and a flashing light signals the caller that the alarm has been received. The central station can then talk to the caller. The caller need not take any other action to communicate with the central station, an important feature when a caller is under stress in an emergency situation.

Versatile, Dependable
The central station operator on receiving a call station signal activates a zone button that illuminates both a flashing red LED and a green "voice" LED. By depressing and releasing the "talk" button, voice communication is established for as long as required. Upon completion, the appropriate zone button is depressed again however, the flashing red light continues. If more than one zone is signaling, the control station accepts the calls in the same manner. When the emergency is resolved, the central station operator pushes a reset button that restores the entire system to stand-by status. In the event of a wiring fault, each annunicator button is equipped with a yellow LED that will illuminate and an alarm that will sound identifying the area requiring service.
