Fence Break Alarm
He made his own using a 120-decibel siren from a home burglar alarm system and an adjustable spring with a threaded bar that attaches to a short length of cord which in turn connects to an electric switch. If cattle break through the fence and the pull cord tightens, it sets off the siren, which Ellis can hear from anywhere on the farm.
