1.1 Safety Information
!
The AFS-3 Audio Failsafe should be installed only by qualified technical personnel. An attempt to install
this device by a person who is not technically qualified could result in a hazardous condition to the
installer or other personnel, and/or damage to the AFS-3 or other equipment. Please ensure that proper
safety precautions have been made before installing this device.
If the AFS-3 is connected so that loss of audio turns a transmitter off, the return of audio could turn the
transmitter back on. Operating and maintenance personnel should be mindful of this possibility and be
sure the transmitter is rendered inoperable before servicing the transmitter, antenna, or associated
equipment.
The purchaser and user of the Sine Systems AFS-3 Audio Failsafe bears the sole responsibility for determining
suitability of this equipment for their intended use.
The AFS-3, as any electronic device, can fail in unexpected ways and without warning. Do not use the AFS-3 in
applications where a life-threatening condition could result if it were to fail. Sine Systems, Inc. cannot be held
responsible for damages, either direct or indirect, resulting from use of this equipment.
Even though the AFS-3 is powered by 12 volts AC from a "wall plug" transformer, failure of this transformer could
cause dangerous and potentially lethal voltages to become present. Only the supplied transformer should be used.
The AFS-3 is designed for indoor use in a dry location. Installation and operation in other locations could be
hazardous.
