SAFETY CONSIDERATIONS

SAFETY PRECAUTIONS

Personnel properly qualified in the application and use of life safety equipment (“qualified personnel”) shall read this

manual carefully before performing any actions to specify, apply, install, maintain and perform operational tests of

IED systems, and associated products in accordance with the instructions in this manual. This manual shall be made

available to all qualified personnel who operate, test, maintain, or service IED systems, and associated products. It is

strongly recommend that such personnel read and understand the entire manual.

WARNING: IF SAFETY PRECAUTIONS, INSTALLATION AND TESTING ARE NOT PERFORMED PROPERLY,

CONDITIONS COULD EXIST IN WHICH THE IED SYSTEM MAY NOT OPERATE, OR MAY OPERATE IMPROPERLY.

THIS COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

AVERTISSEMENT: SI LES MESURES DE SECURITE, L’INSTALLATION ET LES ESSAIS NE SONT PAS EFFECTUES

CORRECTEMENT, CELA POURRAIT EMPECHER LE SYSTÈME IED DE FONCTIONNER, OU DE FONCTIONNER

CORRECTEMENT. CELA POURRAIT PROVOQUER DES DEGATS MATERIELS ET DES BLESSURES GRAVES, OU

LA MORT POUR LES AUTRES ET/OU VOUS-MEMES.

It is very important that only responsible, trained personnel are allowed to operate and maintain these systems, and that

they use only appropriate equipment and tools. If a person is not trained, they shall contact the IED factory for direction

on how to operate and maintain an IED system.

Unauthorized personnel and equipment must be restricted from the areas of operation.

All operations should be performed carefully, methodically, and without hurrying. Greater effectiveness will be developed

by increased familiarity of personnel with their assignments. During any maintenance operation, if a malfunction occurs

or an incorrect indication appears, stop the operation and determine whether or not it is safe to proceed. Before

performing any step in a procedure, be sure that the preceding step has been properly executed and correct results

obtained. Cleanliness and good housekeeping in all installation areas are major factors in effective accident prevention.

Tools and equipment should be maintained in good working order and should always be returned to their proper storage

place after usage. Cleaning agents and other cleaning aids should be removed from the equipment areas immediately

upon completing the task at hand.

GENERAL PRECAUTIONS

Changes, modifications, or additions in connection with the IED system equipment shall not be made without explicit

authorization of IED.

Safety devices found on mechanical, and electrical and electronic equipment are put there for the protection of

personnel and equipment. These devices must be maintained in good working order and operative at all times. Safety

devices shall never be removed or bypassed unless specifically authorized by the IED factory. Where safety devices have

been rendered inoperable by proper and specific authorization, adequate notices shall be posted to warn personnel of

the potential hazard.

Avoid the use of flammable or toxic cleaning fluids, and the use of carbon tetrachloride is prohibited. Maintenance of

the equipment shall be at least what is specified in the IED manuals and literature, and performed only by qualified

personnel. Whenever operation and maintenance is ongoing, personnel in the equipment areas shall have effective

communications among these areas in order to protect people if any accident occurs.

PRECAUTIONS

Precautions which are applicable to general electrical or electronic maintenance are as follows:

a. Check yourself. Wear no article that might catch on equipment or that might act as a conductor.

b. Check the working area. The equipment area shall be clean and dry. If possible, stand on a special insulator such as a

rubber mat. There should be ample working space and good lighting.

c. Check the tools. Always use proper tools and check them for their safe condition. Use screwdrivers with plastic handles.

Check test equipment periodically and examine test leads carefully as the slightest break in insulation is dangerous.

d. Check the procedures. Study the entire procedure before taking the first step. Consult the circuit diagram frequently to

obtain an understanding of what is accomplished at each step. Know what is in the equipment and how it differs from

others on which you have worked.

e. Be aware that high voltages may be present across terminals that are normally low voltage, due to equipment

breakdown. Be careful when measuring low voltages in equipment containing high voltage circuits.

f. Do not make resistance measurements with power on.

g. Do not work within the equipment without the presence of a person who is capable of rendering aid, and who is familiar

with the procedure for emergency shutdown of the equipment.

PRECAUTIONS WHEN MEASURING HIGH VOLTAGE POTENTIALS

Observe the following precautions when measurements must be performed on circuits with potentials over 48 volts.

a. Do not measure potentials over 48 volts without the presence or assistance of a person who is capable of rendering aid,

and who is familiar with the procedure for emergency shutdown of the equipment.

b. Be sure you are not grounded when you are adjusting equipment or using measuring equipment. Stand on a rubber mat

or other insulator if possible. Be sure the equipment area is clean and dry. In general, use only one hand when servicing

live equipment.

c. If a test meter must be held or adjusted while voltage is applied, ground the case of the meter before starting a

measurement. Do not touch the live equipment or personnel working on live equipment while holding the meter. The

“common” terminal on some A/C electronic voltmeters is at ground potential; never connect the “common” terminal to

any point above ground potential.

d. High-voltage, high-capacitance capacitors should be discharged before servicing is started.

WARNING! Discharging must be done carefully and judiciously. First ascertain whether there is a built-in

bleeder network. If so, wait a minute or two for the capacitor to discharge through the network.

Otherwise, use an external discharge network. This is most important in the case of high voltage or high

capacitance capacitors. If one terminal is connected to ground, connect the discharge network between

the other terminal and ground. If neither terminal of the capacitor is grounded, connect the network

across the capacitor terminals. Connecting a short circuit across the terminals is not recommended.

Doing so can produce extremely high currents and a flash which can injure the eyes, vaporize metals,

and cause burns.

AVERTISSEMENT: La décharge doit être faite soigneusement et judicieusement. Vérifier d’abord si il y a

un réseau de purgeur incorporé. Si c’est le cas, attendez une minute ou deux pour que le condensateur

se décharge par le réseau. Sinon, utilisez un réseau de décharge externe. Ceci est très important en cas

de haute tension ou des condensateurs à haute capacité. Si un terminal est relié à la terre, connecter le

réseau de décharge entre l’autre terminal et la terre. Si aucun terminal de condensateur est fondé, relier

le réseau au terminal du condensateur. La connexion d’un court-circuit entre les terminaux n’est pas

recommandée. Cela peut créé des courants très élevés où des étincelles pourrait blesser les yeux,

fondre les métaux et causer des brûlures.

PRECAUTIONS WHEN WORKING ON ENERGIZED EQUIPMENT

When it is necessary to work on energized equipment, think ahead and anticipate every hazard. Never work alone on

energized equipment.

Interlock switches are installed on some of the doors and panels to break the power circuits when the enclosure is

entered. When it is necessary to work within such an enclosure on energized equipment, the interlock may be bypassed.

Extreme caution should then be exercised, as dangerous voltages are present within the unit.

AC POWER CIRCUITS

Equipment obtaining power from a secondary distribution system should be grounded at all times by means of a third

grounding wire on the power lines. Equipment permanently wired to a secondary distribution system should also be

grounded separately by connection to a grounding bus or ground rod with a sufficiently large conductor to handle the

current expected if the secondary source is accidentally shorted to the equipment.

The ground wire should be protected from mechanical damage and periodically inspected for good physical condition.

Personnel should never depend on a switch to remove power from equipment. If the equipment is connected to the

secondary distribution system by means of a power cable, detach the cable from the receptacle before attempting any

repairs of removal of chassis.

If the equipment is permanently wired to the secondary distribution system, remove the main fuses or open the power

switch. Attach a suitable warning tag to the switch which will warn personnel not to operate the equipment; only the

person who originally attaches the warning tag should be authorized to remove it.

RESUSCITATION

Personnel working with or near high voltage should be familiar with modern methods of resuscitation. Such information

and training is available from the Red Cross or local emergency response personnel such as the police and fire

departments.

DESCRIPTION

The DNA2404 series of amplifiers are an integral part of the IED GLOBALCOM Communications System, allowing a few

audio zones to be added where necessary when a full 16-zone T9160 amplifier frame is not required. The amplifiers

feature CobraNet®or Dante™ digital audio input and four channels of output. The DNA2404 amplifiers are controlled

with network commands for selecting input routing and configuring EQ, delay, output levels, and ambient noise

level compensation. Amplifiers may be controlled by a stand-alone GLOBALCOM configuration utility or through the

GLOBALCOM System Management Center.

The internal amplifier cards are Class D (switching mode) dual channel amplifiers.

Class D operation, combined with an integral switching mode power supply, offers many advantages, and the unique

IED design makes full use of these benefits. They include higher efficiency, increased reliability, improved performance,

and lower operating cost. Switching mode operation combined with high voltage power MOSFET devices make it

possible to eliminate the heavy, costly, bulky transformers. IED’s design is stable under all load conditions (phase angles

of 0 to 360 degrees). The amplifier card has 34 dB of gain from its analog input to the loudspeaker output. Attenuation is

handled ahead of the power amplifier by DSP controls through software.

Inputs are provided for connecting up to eight (8) 540S ambient noise sensors (2 sensors for each output channel). This

allows the output of each channel to be automatically adjusted in real time based on the measured ambient noise level in

the zone.

The power amplifier has built-in voltage limiting to protect the loudspeakers being driven. In addition, a temperature

sensor on the heatsink will automatically shut down an amplifier that becomes too hot, such as due to cooling fan

blockage or failure, so as to protect the electronics.

The DNA2404 series amplifiers feature LED indicators for power, audio signals and fault status. A Form C relay is also

included that will indicate that a fault is present.

The DNA2400CL/DL amplifiers provide 70.7 volts for transformer-distributed loudspeaker systems. The DNA2404CH/DH

amplifier provides 100 volts for transformer-distributed loudspeaker systems.

The model DNA2404CL/DL operates from a 120 VAC power source. The DNA2404CH/DH model operate from a 240 VAC

power source.
