IMPORTANT NOTES
SAFETY
PRECAUTIONS
IMPORTANT NOTES
Before connecting and using this paging microphone, 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. All the precautions, in particular the safety ones, must be read with special
attention, as they provide important information.
2. Make sure all connections have been made correctly before switching all
devices on.
Do not connect / disconnect the paging microphone when the system is
operating.
3. Protect paging microphone cables from damage and assure they are
positioned where these cannot be stepped on or crushed by objects.
4. Do not put the paging microphone into water (or another liquid), do not
throw it.
5. Never attempt to carry out any operations, modifications or repairs.
If the paging microphone does not work properly, contact your authorized
service centre.
6. Should the paging microphone emit any strange odour or even smoke, turn
the sound system off immediately and disconnect it.
7. RCF S.p.A. strongly recommends the sound system installation is only
made by professional
qualified installers (or specialised firms), 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.
8. 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.).
9. Do not point the microphone at near loudspeakers, in order to avoid
feedback.

5
ENGLISH
10. 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
therefore necessary to wear ear plugs or protective earphones.
11. To prevent inductive effects from causing hum, noise and a bad system
operating, paging microphone cables should not be laid together with other
electric cables (mains) and loudspeaker lines.
12. Keep the paging microphone far from any excessive heat source.
13. Do not use solvents, alcohol, benzene or other volatile substances for
cleaning the external parts. Just use a dry cloth.

NC: normally closed, COM: common pin, NO: normally open.
Each paging microphone is equipped with a relay, of which dry contacts that
can be used for system monitoring. In monitored systems, paging microphones
supervise MU 7100EN main units.
If a fault (in the main unit or in the transmission path to consoles) is detected,
the ‘System Fault’ indication will be displayed and the control output relay will be
activated.
Paging microphones can be connected to the system with CAT5 (or CAT6) cable.
A dedicated network is highly recommended. Make sure not to use cables already
assigned for Ethernet / Intranet.The digital address must be unique for each unit
linked to a bus and be the same assigned during the system configuration.
DXT 7000EN network structure is a bus wiring from device to device (‘daisy-
chain’), also a star configuration is possible, but the total cable length cannot
exceed 1200 metres.
A system bus can normally provide enough power for all paging microphones (no
need of external power supply units).Anyway, if many units with remarkably long
cables are used, the voltage drop will need to be measured and evaluated.
WIRING AND CONNECTIONS

11
ENGLISH
Paging microphone can be linked in a redundant network in order to get the
highest security against possible cable faults (as according to the EN 54-16
standard).
Paging mic. main bus can be connected to either mu 7100en system bus or local bus.
If a system (redundant) dual bus is needed, the MU 7100EN local bus can be
used as the spare one:
-MAIN BUS port linked to MU 7100EN SYSTEM BUS
-SPARE BUS port linked to MU 7100EN LOCAL BUS.

turn to the idle state.
More than one zone / function button can be selected before paging.
The display shows the selected zone list (from the lowest number to the
highest):
The zone list can be completely erased by pushing either the CL or the 3RESET
key.
When an unconfigured zone / function button has been pushed, an error
message will be displayed:

ENGLISH
4.2. ERROR LOG AND CLEARING
The 'Error log and clearing' function can be displayed only after entering
the access level 2, by inserting the 4-digit code through the zone / function
buttons (see the 4'Key' button).
Push the OK key to enter the error log.
Example: after 'ERROR', the first digit (1 out of 3) is the error index, the
second digit indicates how many errors have been found (total: 3).
The second display row specifies the found error (e.g. PAGING UNIT 23).
The next errors can be seen by using the 2 (up) / 8 (down) keys,
example:
Error details can be seen by pushing the OK key (or push CL to quit):
Error date and time are shown by pushing the 8 (down) key:

Push the 3RESET button to stop the EVACUATION / ALERT message.
During the message play, it is possible to add or remove zones by pushing
the respective zone / function buttons and then ALERT or EVAC again. To
deactivate a single zone, select it and then push the RESET button.
6. OTHER PRE-RECORDED MESSAGES
note: before activating a‘continuous message’, it is necessary to enter the access level
2 by inserting the 4-digit Pin code through the zone / function buttons (see the 4
‘key’ button), while a‘single message’ (Played once only) can be activated from the
access level 1 (the Pin code is not needed).
