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 NOTE: according to EN 54-16 standard, paging microphones shall be only

accessible by personnel 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 paging microphones 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 audio 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.

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 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.

DESCRIPTION

BM 3804 is a desktop paging microphone exclusively dedicated for the RCF DXT 3000 system. It can be directly connected to the MX 3250 main unit through a four-pair J-type re-rated cable.

Up to four BM 3804 paging microphones (interlocked one another) can be linked (daisy-chained) to the line.

BM 3804 front panel includes the following buttons:

- Two for zone selection (rst and second only)

- PTT (‘Push To Talk’)

- GEN CALL (general call)

- CHIME (on / off)

- EVAC message selection

- ALERT message selection, this button also allows to mute the buzzer (when a fault is detected)

- A protected bistable emergency button (with red light) to start playing the evacuation / alert message in all zones.

The system status is indicated by a LED bar.

Every BM 3804 paging microphones can be expanded with an additional BE 3806 keyboard, which has six buttons for the six-zone selection of a complete MX 3250 main unit (with three amplier boards).

The rst BM 3804 paging microphone (of the line) is for emergency purposes and directly powered by the MX 3250 main unit, while the second, the third and the fourth need 24 V dc adapters (500 mA, i.e. RCF AC AD 2405, optional).

Other features:

- Casing in die-cast metal

- Preamplied cardioid hi-quality microphone, with exible 445 mm long

- Comprehensive self-diagnostics (EN 54-16)

- Connection cable included (5 m, with RJ 45).

IMPORTANT NOTE: As the rst paging microphone is for emergency purposes, this shall be placed in premises with access restricted to authorized personnel only.

BM 3804FM is the ‘Firemen’ paging microphone that works in the same way of the BM 3804 model, but with the following differences:

- The paging microphone is inside a wall-mounted metallic box (colour: red, RAL 3000) with glass.

- A handheld microphone with momentary switch (instead of a gooseneck mic.).

- The handheld microphone momentary switch has the same function of the PTT button 3.
