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.

DESCRIPTION
BM 9802 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 9802 paging microphones (or
alternatively, the BM 9804 model, which has three assignable buttons) 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 has a numeric keyboard for zone selection.
All paging microphones also have the ‘Push To Talk’ (PTT), the ‘General Call’
and the ‘Chime’ (On/Off) buttons.
Up to eight BE 9808 keyboards can be linked to every BM 9802 (not used for
emergency purposes).
Each BE 9808 has eight 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.
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.

AVVERTENZE PER
LA SICUREZZA
IMPORTANTE
IMPORTANTE
Prima di collegare ed utilizzare la base microfonica, leggere attentamente le istruzioni
contenute in questo manuale, il quale è da conservare per riferimenti futuri.
Il presente manuale costituisce parte integrante del prodotto e deve accompagnare
quest’ultimo anche nei passaggi di proprietà, per permettere al nuovo proprietario di
conoscere le modalità d’installazione e d’utilizzo e le avvertenze per la sicurezza.
L’installazione e l’utilizzo errati del prodotto esimono RCF S.p.A. da ogni responsabilità.
AVVERTENZE PER LA SICUREZZA
Secondo la norma EN 54-16 (“livello di accesso 2”), i microfoni per annunci d’emergenza
devono essere accessibili solo da persone che hanno responsabilità in materia di sicurezza e
sono formate ed autorizzate ad operare nelle condizioni di inattività, allarme vocale, avviso
di guasto e disabilitazione.
1. Tutte le avvertenze, in particolare quelle relative alla sicurezza, devono essere lette con
particolare attenzione, in quanto contengono importanti informazioni.
2. Prima di accendere le apparecchiature, assicurarsi che tutte le connessioni siano corrette.
Non collegare / scollegare la base microfonica quando il sistema è acceso.
3. Accertarsi che il cavo della base microfonica non possa essere calpestato o schiacciato da
oggetti, al ne di salvaguardarne l’integrità.
4. Non immergere la base microfonica nell’acqua (od in altri liquidi), non lanciarla o lasciarla
cadere.
5. Non eseguire sulla base microfonica interventi / modiche / riparazioni; contattare i centri
di assistenza autorizzati nel caso che non funzioni correttamente.
6. Nel caso che dalla base microfonica provengano stranamente odori anomali od addirittura
fumo, spegnere immediatamente il sistema audio e scollegarla.
7. RCF S.P.A. raccomanda vivamente che l’installazione del sistema audio sia eseguita
solamente da installatori professionali qualicati (oppure da ditte specializzate) in grado di
farla correttamente e certicarla in accordo con le normative vigenti. Tutto il sistema audio
dovrà essere in conformità con le norme e le leggi vigenti in materia di impianti elettrici.
8. I fattori meccanici ed elettrici sono da considerare quando si installa un sistema audio
professionale (oltre a quelli prettamente acustici, come la pressione sonora, gli angoli di
copertura, la risposta in frequenza, ecc.).
9. Non puntare la base microfonica verso un diffusore acustico vicino, onde evitare un
possibile innesco.
10. Perdita dell’udito
L’esposizione ad elevati livelli sonori può provocare la perdita permanente dell’udito. Il livello
di pressione acustica pericolosa per l’udito varia sensibilmente da persona a persona e
dipende dalla durata dell’esposizione. Per evitare un’esposizione potenzialmente pericolosa
ad elevati livelli di pressione acustica, è necessario che chiunque sia sottoposto a tali livelli
utilizzi delle adeguate protezioni; quando si fa funzionare un trasduttore in grado di produrre
elevati livelli sonori, è necessario indossare dei tappi per orecchie o delle cufe protettive.
11. Per evitare che fenomeni induttivi diano luogo a ronzii, disturbi e compromettano il buon
funzionamento dell’impianto, il cavo della base microfonica non deve essere canalizzato
insieme ai conduttori dell’energia elettrica e/o alle linee dei diffusori acustici.
12. Collocare la base microfonica lontano da amme (o fonti di calore eccessivo).
13. Non usare solventi, alcool, benzina o altre sostanze volatili per la pulitura delle parti
esterne, ma un panno asciutto.

RCF S.P.A. VI RINGRAZIA PER L’ACQUISTO DI QUESTO PRODOTTO,
REALIZZATO IN MODO DA GARANTIRNE L’AFFIDABILITÀ E
PRESTAZIONI ELEVATE.
DESCRIZIONE
BM 9802 è una base microfonica esclusivamente dedicata per il sistema
RCF DXT 9000 che può essere collegata direttamente ad un’unità centrale
(es. MU 9186, MX 9502, MX 9504) tramite un cavo antifiamma di tipo “J”
(quattro coppie di conduttori).
È possibile collegare no a sedici basi microfoniche BM 9802 (o, in alternativa,
il modello BM 9804 con 3 tasti assegnabili) a ciascun “bus” dell’unità centrale
del sistema (totale: max. 32 basi microfoniche).
Lo loro congurazione (accesso al sistema) si effettua tramite il software
dedicato per PC.
Sul pannello frontale è presente una tastiera numerica per la selezione delle
zone.
Sono presenti inoltre il tasto per l’attivazione del microfono (PTT, “Push To
Talk”, “premere per parlare”), quello per la chiamata generale (GEN CALL) e
quello per l’abilitazione (o meno) del tono di preavviso prima di un annuncio
(CHIME).
Ogni base microfonica BM 9802 (se non usata per funzioni d’emergenza) può
essere espansa con massimo otto pulsantiere aggiuntive BE 9808, ciascuna
delle quali ha 8 tasti assegnabili (tramite software per PC) ad una delle
seguenti funzioni:
-selezione di zone o gruppi (di zone);
-richiamo di congurazioni (“preset”);
-incrementare o diminuire il volume della musica di sottofondo;
-disattivare (“mute”) o riattivare la diffusione della musica di sottofondo;
-conferma ricevuta segnalazione errore / guasto;
-“reset” eventi d’evacuazione / d’allerta;
-“stop” (senza “reset”) del messaggio d’evacuazione o d’allerta;
-riattivazione del messaggio d’evacuazione o d’allerta;
-segnalazione di guasto;
-attivazione dei messaggi di ne-allarme, di test, di routine.
Le basi microfoniche con funzioni d’emergenza (la prima di entrambi i “bus”)
possono avere al massimo quattro BE 9808 ed il loro tasto ALARM è abilitato.
Tutte le basi microfoniche necessitano di alimentatori esterni 24 V c.c. (500
mA, ad esempio, l’opzionale RCF AC AD 2405).
La prima base microfonica di ciascun “bus” può avere funzione d’emergenza.
In tal caso, la base microfonica dovrà essere direttamente alimentata dall’unità
centrale del sistema DXT 9000 (non serve l’alimentatore esterno, ma occorre
impostare correttamente un selettore interno), come richiesto dalla normativa
EN 54-16.
ATTENZIONE: Ogni modica eseguita da personale non autorizzato
al prodotto e/o al sistema (in cui è installato e congurato,
armadio rack e cablaggi inclusi) può far decadere la marcatura CE
(certicazione EN54-16:2008) e la garanzia del prodotto medesimo.
