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

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

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 switch off the power, 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 your nearest TOA dealer.

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

CAUTION

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

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.
• Do not block the ventilation slots in the unit's cover. Doing so may cause heat to build up inside the unit and result in fire.

• Be sure to follow the instructions below when rack-mounting 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.

• To rack-mount the unit, use the supplied rack mounting hardware.
• When connecting the unit's power cord to an AC outlet, use the AC outlet with current capacity allowable to the unit.

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.

This device is a Class I product.

Connect the supplied power cord only to the AC outlet with a ground terminal. Doing otherwise may result in electric shock.

CONSEILS DE SÉCURITÉ

The N-8000MI is a multi interface unit designed for use with TOA's packet intercom system (IP network-compatible intercom system) that employs the packet audio technology*. Connecting the multi interface to a local area network permits the ideal system for in-house or wide-area information transmission applications, such as paging, periodical broadcasts, and background music broadcasts, to be built between the multi interface and IP intercom exchange or other multi interface unit. The contact bridge function can be realized through contact input and output control.

* Technology related to audio transmission over a network.

Warning

This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

DESCRIPTION GÉNÉRALE

• N-8000MI units can be distributed over a data communications network.
• Can be connected to an existing local area network (LAN) or wide-area network (WAN). The unit can also be easily connected to fiber-optic networks without restrictions on operating distance.
• The dedicated software program enables centralized control with a personal computer.
• System maintenance (verifying operation log and Line supervision) can also be performed with a personal computer and Internet browser.
• Can be connected to the Exchange of the EXES-2000 or EXES-6000 Intercom System by a tie-line, or the PBX exchange via the OD (out-band-dialing) trunk.

8.2. Type of Cable

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

• Twisted pair wires (such as those used for electronic push-button telephone) are to be used for wiring to the audio input/output terminals and PBX interface terminal.
• UTP category 5 Straight through cables with RJ45 connector are to be used for wiring the equipments connected 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 each junction are as follows.

Mini-clamp connector (PBX interface terminal)

Conductor diameter: 0.4 – 0.65 mm (AWG22 – 26), Solid wire

Outside diameter: 1.05 mm or below

Removable terminal plug (Control input/output terminals and audio input/output terminals)

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

8.3. Connector Connection

Mini-clamp connectors for PBX interface terminals and removable terminal plugs for line input and output terminals are supplied with the N-8000MI.

Perform each connector connection as follows.

8.3.1. Mini-clamp connector connection

Step 1. Cut off two-cable ends in equal length, and insert them securely to a cover section (transparent side) of the mini-clamp connector.

Note

Insert the cable without stripping the cable jacket. For cables, refer to the above section, Type of Cable.

Step 2. With a pair of pliers, lightly pinch the mini-clamp cover and, after ensuring that the cable is securely inserted, firmly squeeze on the cover.

Note

Squeeze on the mini-clamp cover until it is correctly locked.

8.3.2. Terminal plug connection

Step 1. Strip a cable jacket of approx. 7 mm from the cable end.

For cables, refer to p. 15, "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.
