A Communication Need:

The Americans with Disabilities Act (ADA) now being enforced,cornell 4200 Area of refuge rescue assiatance requires an Area of Refuge system in all newly constructed multi-story commercial buildings and public accommodations to provide a means to request evacuation assistance in emergencies. The ADA also applies to significant renovations of existing multi-story facilities.

A Reassuring Solution:

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.

Improved Surface Finish:

Our new self cleaning ceramic polymer coating preserves and protects the annunciator surface finish.

Larger Sizes Available:

Now available in standard sizes to 44 zones. Call factory for larger applications.

Versatile, Dependable:

The control station operator, on receiving a call station signal, activates a zone switch 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 control station operator pushes a reset switch that restores the entire system to stand-by status. In the event of a wiring fault, each annunciator zone is equipped with a yellow LED that will illuminate and an alarm will sound identifying the area requiring service.
