2.1
The AFS-1 Audio Failsafe should be installed only by qualified technical personnel.
Incorrect or inappropriate installation could result in a hazardous condition.
Service of the AFS-1 Audio Failsafe should be performed only by qualified technical
personnel. Even though the AFS-1 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.
Because of exposed terminals, high voltage (greater than 25 volts) should not be connected
to the relay terminals, or any other terminals on the AFS-1.
If the AFS-1 is connected so that loss of audio turns a transmitter off, the return of audio
could turn a transmitter back on. Operating and maintenance personnel should be
mindful of this possibility and be sure the transmitter is rendered inoperable before
maintenance is begun on the transmitter, antenna, or associated equipment.
The AFS-1 is designed for indoor use in a dry location. Installation and operation in other
locations could be hazardous.
