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.
