IMPORTANT NOTES
Before connecting and using this console, please read this instruction manual carefully and keep
it on hand for future reference. The manual is to be considered an integral part of this product and
must accompany it when changing ownership as a reference for correct installation and use as
well as for the safety precautions. RCF S.p.A. will not assume any responsibility for the incorrect
installation and / or use of this product.
SAFETY PRECAUTIONS
1. According to EN 54-16 standard, paging microphones shall be only accessible by persons
having a specic responsibility for safety and who are trained and authorized to operate in the
following conditions: quiescent, voice alarm, fault warning and disablement.
2. All the precautions, in particular the safety ones, must be read with special attention, as they
provide important information.
3. Make sure all connections have been made correctly before switching all devices on.
Do not connect / disconnect this console when the system is operating.
4. Protect console cables from damage and assure they are positioned where these cannot be
stepped on or crushed by objects.
5. Do not put this console into water (or another liquid), do not throw it.
6. Never attempt to carry out any operations, modications or repairs.
If the console does not work properly, contact your authorized service centre.
7. Should the console emit any strange odour or even smoke, turn the sound system off
immediately and disconnect it.
8. RCF S.p.A. strongly recommends the sound system installation is only made by professional
qualied installers (or specialised rms), who can certify it according to the regulations in force.
The entire audio system must comply with the current standards and regulations regarding
electrical systems.
9. Mechanical and electrical factors need to be considered when installing a professional audio
system (in addition to those which are strictly acoustic, such as sound pressure, angles of
coverage, frequency response, etc.).
10. Do not point the microphone at near loudspeakers, in order to avoid feedback.
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that
leads to hearing loss is different from person to person and depends on the duration of exposure.
To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is
exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is necessary to wear
ear plugs or protective earphones.
12. To prevent inductive effects from causing hum, noise and a bad system operating, microphone
cables should not be laid together with other electric cables (mains) and loudspeaker lines.
13. Keep the console far from any excessive heat source.
14. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external
parts. Just use a dry cloth.

DESCRIPTION
IN 9000 is an emergency reman console designed to be interfaced with the RCF DXT
9000 evacuation system, in order to provide an analogue backup solution for emergency
communications, in case of interruption of the main digital connection RCFBUS.
This console is protected by a wall-mounted red metallic box with glass and equipped with
a monitored handheld microphone having a momentary ‘Push-To-Talk’ (PTT) button.
The PTT command is also available as front panel button, together with a VU-meter LED
bar (microphone signal level) and an ‘IN USE’ LED.
IN 9000 needs an external 24 ÷ 48 V dc power supply EN54-4 providing at least 20W
output power. Moreover, a monitored GPI is provided to report any power supply fault.
The audio output can be distributed up to 64 DXT 9000 units and routed to 4 independent
lines selectable on the console front panel.
A dedicated (optional) RCF OT 3500 audio transformer can be installed on each output
line.
MAIN FEATURES
-Monitored reman’s microphone with PTT button.
-The console is protected by a wall-mounted red metallic box with glass.
-Fully analogue connection (in the event of interruption of RCF BUS).
-Output signal can be sent to max. 64 DXT 9000 units over 4 selectable independent
lines.
-2 monitored GPI (‘General Purpose Input’): power supply and DXT 9000 fault.
-1 monitored GPO (‘General Purpose Output’) to report a console fault to DXT 9000.
-Power supply range 24 ÷ 48 V dc (external 20 W power supply required).
-Front panel fault reporting: general, microphone, command port, power supply, power
supply GPI, DXT general, DXT general GPI.
IMPORTANT NOTES
IN 9000 shall be placed in a room with access restricted to authorized
personnel only, within a protected area not subjected to conditions that may
affect its operation, for example: moisture, salt, water inltration, extreme
temperatures, shocks, etc.
It should be placed at a height from the oor that makes it easily accessible.
Also check the suitability of the wall and the components used for attachment (wall plugs,
screws, not supplied by RCF), which must guarantee the system security over time, also
considering, for example, the mechanical vibrations normally generated by transducers.
RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
WARNING:
Any change made by unauthorized personnel to the product and / or the
system (in which it is installed and congured, including rack cabinet and
wiring) may invalidate the CE marking (certication EN54-16: 2008) and also
the product warranty.

SYSTEM CONNECTIONS
IN 9000 can be connected to several rack cabinets (including DXT 9000 main units
and ampliers), routing its audio output through max. 4 independent lines.
For example, next 2 gures show 2 possible wirings: the former 1is the most
simple one (using only one output line), the latter 2is the most complex one
(using all the 4 output lines).
Of course, any layout in between is possible, depending on installation
requirements.
