The 4200 Series Audio Rescue Assistance System is a time proven 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 annunciator panel and optional access to a public telephone line. A single pulse tone and a flashing light signals the caller that the alarm has been received. The control station can then talk to the caller. The caller need not take any other action to communicate with the control station, an important feature when a caller is under stress in an emergency situation.
