Important safeguards

1 Read instructions - All the safety instructions for use

should be read before the system is operated.

2 Retain instructions - The safety instructions and

instructions for use should be retained for future reference.

3 Heed warnings - All warnings on the unit and in the

operating instructions should be adhered to.

4 Follow instructions - All operating instructions and

instructions for use should be followed.

5 Cleaning - Unplug system units from the mains outlet

before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

6 Attachments - Do not use attachments not

recommended by the product manufacturer as they may cause hazards.

7 Water and Moisture - Do not use this unit near water, for

example near a bathtub, washbowl, kitchen sink, or laundry basket, in a wet basement, near a swimming pool, in an unprotected outdoor installation or any area which is classified as a wet location.

8 Accessories - Do not place this unit on an unstable stand,

tripod, bracket or mount. This unit may fall, causing serious injury to a person and serious damage to the unit. Use only a stand, tripod, bracket or mount recommended by the manufacturer, or sold with the product. Any mounting of the unit should follow the manufacturer's instructions, and should use a mounting accessory recommended by the manufacturer. An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn.

9 Ventilation - Openings in the enclosure, if any, are

provided for ventilation and to ensure reliable operation of the unit and to protect it from overheating. These openings must not be blocked or covered. The unit should not be placed in a built-in installation unless proper ventilation is provided or the manufacturer's instructions have been adhered to.

10 Power sources - Units should be operated only from the

type of power source indicated on the marking label. If you are not sure of the type of power supply you plan to use, consult your appliance dealer or local power company. For units intended to operate from battery power, or other sources, refer to the "Installation and User Instructions".

11 Grounding or polarisation - This unit may be equipped

with a polarised alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug still fails to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarised plug. Alternatively, this unit may be equipped with a 3-wire grounding type plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type lug.

12 Power-Cord Protection - Power supply cords should be

routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience receptacles, and the point where they exit from the appliance.

13 Overloading - Do not overload outlets and extension

cords as this can result in a risk of fire or electrical shock.

14 Object and Liquid Entry - Never push objects of any

kind into this unit through openings as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the unit.

15 Servicing - Do not attempt to service this unit yourself as

opening or removing covers may expose to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

16 Damage Requiring Service - Unplug the unit from the

outlet and refer servicing to qualified service personnel under the following conditions:

• When the power-supply cord or plug is damaged.

• If liquid has been spilled, or objects have fallen into the unit.

• If the unit has been exposed to rain or water.

• If the unit does not operate normally by following the instructions for use. Adjust only those controls that are covered by the instructions for use, as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the units to their normal operation.

• If the unit has been dropped or the unit has been damaged.

• When the unit exhibits a distinct change in performance; this indicates a need for service.

17 Replacement Parts - When replacement parts are

required be sure the service technician has used replacement parts specified by the manufacturer or parts which have the same characteristics as the original part. Unauthorised substitutions may result in fire, electric shock or other hazards.

18 Safety Check - Upon completion of any service or

repairs to the units, ask the service technician to perform safety checks to determine that the unit is in proper operating condition.

19 Lightning - For added protection of the units during a

lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the cable system. This will prevent damage to the unit due to lightning and power-line surges.

Plena Message Manager | Installation and Operating Manual | en | 8

The Plena Message Manager functions as an audio source in the overall Plena PA-system. With this unit it is possible to play, via other Plena units, pre-recorded messages that are triggered from external sources or the unit's front panel switches. These pre-recorded messages (that can be made on a PC in .wav-format) can be used for various purposes, e.g. routine messages or emergency calls. The messages are stored in solid state memories (Eeproms) and are continuously supervised on availability. When the message manager is connected to the Plena System Pre-amplifier (LBB1925), it is also possible to distribute the messages in pre-programmed zones.

The unit is delivered with the mains voltage selector set to 230 Vac. This selector can be set to 115 Vac. The unit is not provided with a separate power ON indication. One message LED on the front panel will always be lit (thus functioning as a power ON indication) as at least one message will be loaded. In case no messages are loaded, this fault situation is indicated by the fault LED.

About the equipment

1.1 Featur es

- Up to 12 different messages can be stored.

- Up to 12 message sequences or announcements (each consisting of up to 4 different messages + zone information) can be stored.

- Messages can be edited, assembled and uploaded by means of a PC.

- The message content is continuously supervised on availability.

- The cabling of trigger inputs 1 through 6 can be supervised on cuts and short-circuits.

- Mains supply voltage (230/115 Vac) can be supervised.

- Pilot tone can be added to supervise the audio connection to an amplifier or the sound system.

- Internal pilot tone to supervise the internal audio path.

- Support for various sample frequencies to balance audio quality versus message length

1.2 Capacity

The storage device of the messages is a built-in block-erasable EEPROM with fixed storage capacity of 8.38 MByte. The message manager accepts .wav-files with sample frequencies of 24, 22.050, 16, 12, 11.025 and 8 kHz. The word length is fixed to 16 bits. This means that the distortion and signal to noise level is of CD quality. Lower sample frequencies mean a decrease in audio quality (lower bandwidth), but an increase in message length. See the table below.

Sample frequency 24 kHz 22.050 kHz 16 kHz 12 kHz 11.025 kHz 8 kHz

Audio bandwidth (approx.) 11 kHz 10 kHz 7.3 kHz 5.5 kHz 5 kHz 3.6 kHz

Max. length of all 12 messages 170 s 180 s 250 s 335 s 360 s 500 s
