CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
CAUTION
• Do not connect the speaker line to the contact output as doing so may result in fire or electric
shock.
• As up to 100 V is applied to the CN 1 terminal, never touch its terminal to avoid electric shock.
Leave all cable connections on the unit to a professional electrical contractor.
2. GENERAL DESCRIPTION
VM-3000 detects speaker line short circuits and open circuits by monitoring the terminated
resistance value of the End-of-line (EOL) unit.
Connecting the VM-300SV unit to the end of the speaker line eliminates the necessity of using the
speaker line for line monitoring.
Note: This unit can only be used on a VM-3000 system with a firmware of 2.00 or later.
3. HANDLING PRECAUTIONS
• Do not install the unit in locations exposed to the direct sunlight or heaters, as the unit could be
deformed or discoloured.
• Avoid installing or storing the unit in dusty or humid locations, as doing otherwise could cause the
unit's failure.
• Keep a unit as far away as possible from a fluorescent lamp, digital equipment, PC or other
equipment which generate high frequency noise.
• Because the unit is not "hot-pluggable," the system needs to be shut down when it is installed or
removed.
• Note correct polarity (positive and negative orientation) when connecting Contact output.
Reserved polarity connections will cause failure.
