4200 Series Audio-Visual Rescue Assistance Systems

The Americans with Disabilities Act (ADA) now being enforced, requires a Rescue Assistance System in all newly constructed multi-story commercial buildings and public accommodations to provide a means to request evacuation assistance in the event of an emergency. The ADA also applies to significant renovations or alterations of existing multi-story facilities. 

The most effective solution is the Alpha Communications® / Cornell 4200 series audio-visual Rescue Assistance System, which signals the need for evacuation assistance. The 4200 series includes voice communication which is initiated by simply depressing the call station button, which transmits the signal to a master station. A single pulse tone and a flashing light signals the caller that the alarm has been received. The master station may then talk to the caller. The caller need not take any other action to communicate with the master station, which is an important feature when a caller is under stress in an emergency situation. For additional safety, a live 'fault' lamp will signal at the central (master) station, if the wiring has been faulted. 

The 4200 series is designed to accommodate up to 44 remote locations for each master station. The smallest master station is a 4-unit and the capacities increment in groups of 4 to a maximum of 44 (or more with custom-sized masters). Master and remote stations are made of rugged Stainless Steel and Anodized Aluminum. Master stations emit a loud, clear tone signal that commands an immediate response. 

The master station operator, upon 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 LED continues. If more than one zone is signaling, the master station accepts the call(s) in the same manner. When the emergency is resolved, the master station operator pushes a Reset button and restores the entire system to stand-by status. In the event of a wiring fault, each annunciator button is equipped with a Yellow LED that will illuminate, and an alarm will sound, identifying the zone requiring service.

The standard audio-visual (anti-vandal) remote call station is the model 4201B/V. The 4201B/V is designed for indoor or outdoor use. The 4201B/V features a metal call button, heavy duty speaker and tamper-resistant mounting screws, and is designed for indoor or outdoor use. The new model 4201B/VM is the same as the 4201B/V except for a large Red Mushroom head call button. Both models fit neatly into a two gang electrical box (or plaster ring).

Each master station is powered by a model# B-5243A power supply. The B-5243A power supply contains the back-up batteries and battery charger required or specified. Because of the critical nature of these systems, the battery back up should be used only as temporary power until this system can be connected to the building's emergency generator, should there be one.

We also offer a complete line of Rescue Assistance Signage. This includes a series of battery powered room identification signs, brand new photoluminescent signs, as well as direction and location signs. These signs meet ADA specifications for use with Areas of Rescue Assistance. See our specification sheet APS478 for more information on the signage available.
