INSTALLATION MANUAL

CEILING MOUNT FIRE DOME SPEAKER

Thank you for purchasing TOA’s Ceiling Mount Fire Dome Speaker.

Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

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.

•  Use  only  the  specified  amplifier  output  voltage 

and impedance, as exceeding the specified limits 

could result in fire or other failures (high-impedance 

applications).

•  To avoid accidental air explosions, do not use the 

unit around gasoline, thinner or other combustibles.

•  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.

•  Do not use other methods than specified to mount 

the  unit.  Extreme  force  is  applied  to  the  unit  and 

the unit could fall off, possibly resulting in personal 

injuries.

•  Tighten  each  nut  and  bolt  securely.  Ensure  that 

the  bracket  has  no  loose  joints  after  installation 

to  prevent  accidents  that  could  result  in  personal 

injury.

•  Avoid  mounting  the  unit  in  locations  exposed  to 

constant  vibration.  The  mounting  bracket  can  be 

damaged by excessive vibration, potentially causing 

the speaker to fall, which could result in personal 

injury. 

•  To avoid electric shocks, be sure to switch off the 

amplifier power when connecting the speaker.

•  Avoid installing the unit in humid or dusty locations, 

or in locations exposed to heaters, solvents, acid, 

alkali, smoke, or steam, as excessive exposure to 

these factors could result in the speaker falling off, 

electric shock or fire.

•  Do not operate the unit for an extended period of 

time with the sound distorting. This is an indication 

of a malfunction, which in turn can cause heat to 

generate and result in a fire.

•  Have  the  unit  periodically  checked  by  the  shop 

from where it was purchased. Failure to do so could 

result in the speaker falling off due to damage or 

corrosion to the speaker or its mounts, and possible 

personal injury.

Indicates a potentially hazardous situation which, 

if  mishandled,  could  result  in  death  or  serious 

personal injury. 

WARNING

Indicates a potentially hazardous situation which, 

if mishandled, could result in moderate or minor 

personal injury, and/or property damage.
