1. SAFETY PRECAUTIONS

• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.

• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.

• After reading, keep this manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

WARNING

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

WARNING

When Installing the Unit

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.

• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.

• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.

• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.

When the Unit is in Use

• Should the following irregularity be found during use, immediately disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.

· If you detect smoke or a strange smell coming from the unit

· If water or any metallic object gets into the unit

· If the power supply cord is damaged (exposure of the core, disconnection, etc.)

· If it is malfunctioning (no tone sounds.)

• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to qualified service personnel.

• Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit's cover, as this may result in fire or electric shock.

• Do not touch a plug during thunder and lightning, as this may result in electric shock.

CAUTION

When Installing the Unit

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

• Be sure to follow the instructions below when rackmounting the unit. Failure to do so may cause a fire or personal injury.

· Install the equipment rack on a stable, hard floor.

Fix it with anchor bolts or take other arrangements to prevent it from falling down.

4

· When connecting the unit's power cord to an AC outlet, use the AC outlet with current capacity allowable to the unit.

· The supplied rack-mounting screws can be used for the TOA equipment rack only. Do not use them for other racks.

When the Unit is in Use

• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

• Do not stand or sit on, nor hang down from the unit as this may cause it to fall down or drop, resulting in personal injury and/or property damage.

2. GENERAL DESCRIPTION

TOA's N-8000DI is Direct select unit used for the N-8000 Series Packet Intercom System (IP network compatible intercom) employing packet audio technology* 1 .

It is equipped with each 32 contact input and outputs, and the indicators on the front panel indicate the output statuses.

5. INSTALLATION

The N-8000DI can be installed in any of three ways: (1) equipment rack mounting, (2) wall mounting, and (3) desk-top installation.

5.1. Equipment Rack Mounting

A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature

(Tma) specified by the manufacturer.

B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.

Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips)."

The N-8000DI can be mounted on the CR -273 or CR -413 or standard EIA 19" Equipment rack.

For the CR -273 and CR -413 Equipment rack assembly, read the installation manual supplied with the rack.

Note

When installing the N-8000DI, lay the equipment rack down face-up to do installation work safely.

5.1.1. Setting space

For maintenance works, allow much space between the wall and Equipment rack.

4. Network connection

Can be connected to a network of 10BASE-

T/100BASE-TX in auto-sensing.

Use a straight through cable of UTP category 5 or more for this connection.

6.2. Type of Cable

The types of cables are to be determined according to the following conditions.

• UTP category 5 Straight through cables with RJ45 connector are to be used for connecting to IP network.

• The number of cables pairs laid should be determined considering the possibility of future expansion of the system.

• Outdoor wires should be used where wiring passes through inaccessible areas such as ceilings or under floors where the maintenance is not performed. Indoor wires may also be used, however, in case where there is no risk of deterioration due to exposure to heat, etc.

Note

Specifications related to junction are as follows.

Removable terminal plug (N-8000DI Control I/O terminal)

Conductor diameter: ø 0.5 – 2 mm (AWG12 – 24), Solid wire/Stranded wire

6.4. Removable terminal plug connection

Step 1. Strip a cable jacket of approx. 7 mm to expose inner cable.

7 mm

For cables, refer to p. 11, Type of Cable.

Note

Do not solder plate on exposed inner cables when using a stranded wire.

Step 2. Loosen the terminal screws and insert the cables.

Step 3. Tighten the terminal screws securely.

Notes

• Tug lightly on the cable to be sure that it does not pull free. If the cable pulls free, loosen the terminal screw again and reconnect from Step 2.

• Use the screwdriver appropriate to the screws tightened into the terminal plug.

Step 4. Insert the wired terminal plug into the terminal block of the N-8000DI.
