Distributed Panel, 4 Fire Phone Circuits. The Bosch EVAX System for high-rise applications is a networked emergency relocation and paging system with integrated two-way fireman’s telephone system. It operates with the Fire Alarm Control Panel (FACP) in a building to provide automatic response to life safety emergencies. While providing all necessary features for an effective voice evacuation system, it can easily convey evacuation, stay-in-place, or other public address announcements and automatic messages with multiple channels of simultaneous audio. Configure your system to include Fire Fighter Phones or Warden Stations as required, for fire fighter communications to supplement 2-way radios and for use in areas of refuge assistance so trapped individuals can communicate with fire command.
