Diagnostic functions and fault reporting meet all evacuation system requirements.
Wiring is limited to a twin pair J-type fire-rated cable for most of connections and to a four-
pair J-type fire-rated cable to link paging microphones.
The system configuration can be edited on the main unit front panel (for small systems),
but it can also be made through a local or remote PC, by using a dedicated graphic user
interface software.
The dual power supply allows both AC and DC operation.
The ‘RCF D+ Class’ power amplifier technology and recover-fall-back built-in facility make
the DXT 9000 a highly secure, reliable and safe system.
Each DXT 9000 unit is equipped with an RS 485 serial port to be used for the dedicated
system programmable remote controls. Noise detection devices work on RS 485 port as
well.
Two pre-recorded messages can be simultaneously played and sent to the DXT 9000
network from main units, which can store both emergency messages (to a checked
dedicated memory) and routine messages (on separated SD cards).
Another SD/USB support is used as MP3 player (to play background music).
The Ethernet port (on main units) allows to get the complete remote control of the whole
system.
DXT 9000 devices have programmable logic inputs and outputs, checked by the system
itself or by the connected security/emergency devices, such as fire alarm systems.
Each component has its own digital address.
DXT 9000 includes high quality digital components already in use for RCF professional
audio systems, obtaining high performances and qualifying the DXT 9000 system for
installations in places that require a very good sound reproduction, such as theatres and
auditoriums.
