Installation Precautions (For Sales Shops and Installers)

• When inspecting the speaker line insulation, disconnect the speaker lines from the PA system.

• If the system's fire alarm (EL) and fire confirmation signal (EF) terminals are connected during a
dielectric strength test of the relay contact of a fire alarm system or other external systems, this
can cause damage to the PA system.

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.

• Ensure that the voltage selector is properly set to
the local power voltage. Wrong settings may cause
a fire or electric shock.

When the Unit is in Use

• Should the following irregularity be found during
use, immediately switch off the AC breaker 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 unit falls, or the unit case breaks

· 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 place cups, bowls, or other containers of
liquid on top of the rack. If they accidentally spill
into the mounted units, this may cause a fire or
electric shock.

• 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.

1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section carefully before use.

• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.

• We also recommend you keep this instruction 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.

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

WARNING

CAUTION

5

When Installing the Unit

• Never plug in nor remove the power supply plug

with wet hands, as doing so may cause electric
shock.

• Do not block the upper panel ventilation slots in the

unit's cover. Doing so may cause heat to build up
inside the unit and result in fire.

• Avoid installing the unit in humid or dusty locations,

in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.

When the Unit is in Use

• Make sure to observe the following handling
precautions so that a fire or personal injury does
not result from leakage or explosion of the battery.

· Do not short, disassemble, heat nor put the

battery into a fire.

· Do not solder a battery directly.

· Be sure to use the specified type of batteries.

· Note correct polarity (positive and negative

orientation) when installing a battery in the unit.

· Avoid locations exposed to the direct sunlight,

high temperature and high humidity when storing
batteries.

3.2. About the Emergency Power Supply

3.2.1. Selection of the emergency power supply panel and battery

The emergency PA system is designed to operate on both the main power supply and emergency power
supply. Because the emergency system needs to be operated for ten minutes or more during a power failure,
the emergency power supply suited to the system scale is required. The FS-970 series systems require the
emergency power supply panel DS-029B and Ni-Cd battery NDC-2435 or NDC-2460. The following table
provides guidelines on the number of emergency power supply panels and Ni-Cd batteries necessary for the
system.

Notes

• This table assumes that the main rack system and emergency remote control unit are identical in the
number of broadcast zones. It is also assumed that no other components are connected other than the EP­029, EP-0510, EP-059R, JP-039, and JP-0410, and that any component is not connected to the emergency
power-off output or emergency output. In some systems, the number of zones may be less than those
shown in the above table.

• Refer to the connection examples on p. 27-30 for connection methods a-d of the Emergency Power Supply
Panel DS-029B.

3.2.2. DC power supply panel expansion

When multiple operation sections or emergency remote control units are connected to the main rack, the DC
power supply panel is required in addition to the Emergency Power Supply Panel DS-029B. For its
connection, refer to "DC Power Supply Panel Connection" on p. 34.

6. EQUIPMENT RACK ASSEMBLY AND INSTALLATION

6.1. Poor Installation Locations

Avoid installing the rack in the following locations.

• Locations that may be exposed to fire, heat or direct sunlight (ambient temperature should be between 0°C
and 40°C).

• Locations that may be exposed to rainwater, steam or high humidity.

• Locations exposed to vibration.

• Locations offering limited space at the rear of the rack for inspection.

• Locations where particles of metal or dust accumulate, or near chemicals or oil.

• Locations near high-voltage equipment or equipment sensitive to electro-magnetic fields.

6.2. Rack Assembly

• Follow the instructions in the manual attached to the rack to assemble.

• When installing the rack components, lay the rack down face-up as shown in the figure to facilitate work and

ensure safety. (For component installation, refer to Component Installation on p. 18.)

• Install the Blower Unit BU-412 after rack assembly completion but before installing each rack component.

Note

Some components require their functions to be readjusted before they are installed in the rack. In such cases,
install the components after readjustment completion. (Refer to p. 15.)

6.3. Rack Installation

The emergency rack system must be installed as shown in the figure below.

• To prevent the equipment rack from falling down due to an earthquake, etc., secure the rack to the floor with

anchor bolts and to the wall with brackets.

• When installing the general rack system, also allow for the above spacing to facilitate maintenance.

6.4. Securing the Rack CR-272 or CR-412 to the Floor

Four anchor bolt mounting holes (ø15 mm) are provided in the rack bottom surface to secure the rack to the
floor. Referring to the figure below, make holes in the floor, then secure the rack to the floor using four M10­M12 anchor bolts.

Eyebolts for suspension can be mounted to the rack top panel.

• Purchase the following parts separately in the market.

Eyebolts M16 ............... 4 pieces

Nut M16 ....................... 4 pieces

Plain washer M16 ........ 4 pieces

Remove four rubber hole covers provided on the top panel, and install eyebolts (4 places) in the exposed
holes as shown in the figure.

Important: The maximum rack system weight for 4-point suspension is 300 kg.

6.8. Fine Height Adjustment of the Installed Rack

When the rack installed on the floor is unstable and shaky, make fine adjustment of its height by turning
clockwise the height adjustment screw located in the front of the bottom rack base. Use the standard
screwdriver for adjustment.

6.9. Grounding

Provide grounding terminals using three grounding terminal screws (M5) located at the rear of the bottom rack
base. Three female screws (M5) are located in the front of the base. Use these screws as required.

Remove this rubber hole cover.
