WARNING
When Installing the Alarm Input Unit…
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as
doingotherwise may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage other than that which is specified
may result in fire or electric shock.
• Do not cut, kink, or otherwise damage or modify the power supply cord. Also, 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 otherwise 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.
Failure to follow this instruction may result in the unit falling down and causing personal injury.
• Do not install the unit in close proximity to medical equipment since the electromagnetic wave from the unit
may adversely affect the medical equipment.
When Using the Alarm Input Unit…
• Do not place cups, bowls, or other containers of liquids or metal objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire or electric shock.
• Do not insert foreign objects, such as metal objects and flammable materials, into the unit through the unit's
ventilation slots, as this may result in fire or electric shock.
• Do not touch a power supply plug during thunder and lightning, as this may result in an electric shock.
• Do not open nor modify the unit's case to prevent a fire or electric shock because there are high voltage
components inside the unit. Refer all inspection, adjustment and repair work to the dealer from where the
unit was purchased.
• Should any of the following irregularities be found during use, immediately switch off the power, disconnect
the power supply cord from the AC outlet and contact your TOA dealer. Do not attempt to further use the
unit because a fire or electric shock may result.
• If you detect smoke or a strange smell coming from the unit.
• If water or a foreign object enters the unit.
• If the unit falls or the unit case breaks.
• If the power supply cord is damaged (exposure of core or disconnection).
• If no image is displayed.

Indicates a potentially hazardous situation which could result in
moderate or minor personal injury, and/or property damage if ignored
or mishandled.
CAUTION
When Installing the Alarm Input Unit
• Never insert nor remove the power supply plug with wet hands, as an electric shock may result.
• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord
itself. The power supply cord may be damaged, possibly causing a fire or electric shock.
• Do not block the ventilation slots in the unit's cover. Doing otherwise may cause heat to build up inside the
unit, possibly causing a 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 moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the
power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock.
• When mounting the C-AL80 Alarm Input Unit in an equipment rack, ensure that the temperature inside the
rack is lower than its maximum ambient temperature.
When Using the Alarm Input Unit
• Do not place heavy objects on the unit. Such objects may fall or the unit may tip over, possibly resulting in
personal injury.
• Clean the inside of the unit periodically, and contact your TOA dealer regarding the cleaning. If dust is
allowed to accumulate in the unit over a long period of time, a fire may result.
• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean them
periodically. Also, insert the plug in the wall outlet securely.
• Switch off the power and unplug the power supply plug from the AC outlet for safety purposes when cleaning
or leaving the unit unused for a long period of time. A fire or electric shock may result.
2. GENERAL DESCRIPTION
Using no-voltage contact inputs, TOA's C-AL80 Alarm Input Unit activates the remote controller's alarm
facilities or remotely controls the remote controller. The C-AL80 has a total of 32 alarm or remote inputs. By
making master-sub connections, up to 8 C-AL80 units can be connected to each other, creating a total of 256
alarm/ remote inputs.
3. HANDLING PRECAUTIONS
• Use the C-AL80 Unit in locations where the temperature fluctuates in the range of 0 – 40°C, and humidity is
under 90% (no condensation must be formed).
• When permanently installing the Unit, avoid blocking ventilation slots in the Unit's cover and bottom panel,
and keep the Unit's front, rear, and sides at least 10 cm from the wall. Doing otherwise may cause heat to
build up inside the Unit and result in the Unit's failure.
