Area of Rescue Assistance Systems are designed to provide communication between 'safe areas' and the building lobby or fire command center.  For example, floor landings within a protected stairwell may be designated safe area for the handicapped where a remote call station with appropriate signs is located.  When the remote station is activated by pressing the call button, an alert tone and selector button is activated at the master station.  The emergency response crews may then communicate to the calling station through the built in intercom. Building codes and the ADA require rescue assistance systems in some buildings.  These systems may also be used in other applications requiring communication to a central location such as parking garages.  Systems from Cornell Electronics and TekTone are available from AppliCom.  Wiring is normally simple, requiring a minimal number of common conductors to all stations, typically 18 AWG, plus a shielded pair of 22 AWG home run from each station to the master.  Refer to the specific system installation manual for exact cable requirements.
