SAFETY PRECAUTIONS

IMPORTANT
NOTES

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

According to EN 54-16 standard (‘access level 2’), paging microphones shall be only
accessible by persons having a specic responsibility for safety and who are trained and
authorized to operate in the following conditions: quiescent, voice alarm, fault warning
and disablement.

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, modications 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 qualied 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.

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.

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 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.

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 congured,
including rack cabinet and wiring) may invalidate the CE marking
(certication EN54-16: 2008) and also the product warranty.

DESCRIPTION

BM 9804 is a desktop paging microphone exclusively dedicated for the RCF
DXT 9000 system.
It can be directly connected to a main unit (i.e. MU 9186, MX 9502, MX 9504)
through a four-pair J-type re-rated cable.

It is possible to link up to sixteen BM 9804 paging microphones (or alterna­tively, the BM 9802 model, which has a numeric keyboard) to each main unit
bus (total: max. 32 paging microphones).
Their conguration (in terms of access) can be set by the dedicated PC sof­tware.

Its front panel includes three buttons that can be set (by using the dedicated
PC software) to:

- Select zones or zone groups.

- Recall presets.

- Increase / Decrease the background music volume.

- Mute / unmute the background music.

- Fault acknowledgement.

- Reset evacuation / alert events.

- Stop (without resetting) evacuation / alert messages.

- Reactivation of evacuation / alert messages.

- Fault indication.

- Activation of all-clear, test and routine messages.

All paging microphones also have the ‘Push To Talk’ (PTT), the ‘General Call’
and the ‘Chime’ (On/Off) buttons.

Up to eight BE 9808 (additional 8-zone-button) keyboards can be linked to
every BM 9804 (not used for emergency purposes) to increase the number of
available buttons.
The paging microphones used for emergency purposes (the rst of each bus)
can have max. four BE 9808 and their ALARM button can be enabled.

All paging microphones need to be powered by external 24 V dc adapters (500
mA, i.e. optional RCF AC AD 2405).
The rst paging microphone of each bus can be used for emergency purposes.
In this case, the paging microphone shall be directly powered by the DXT 9000
system main unit (no need of an external adapter, but it will be necessary to
set an internal switch) as required by the EN 54-16 standard.

The switch is on the PCB, near the fuse and the input for the adapter.

If the paging microphone is the rst of the line and is for emergency purposes,
set this switch from Vcon (paging microphone supplied by the external adapter)
to Vnet (supplied by the bus).
Then, remount the rear cover.

WARNING: the internal switch setting shall be carried out only by either
RCF or an authorised service centre.

First, remove the rear cover by unscrewing its 6 screws.
