Abstract: A transmitter and a water system or distribution protection device, such as a fire hydrant protection device, is disclosed. The water system protection device inhibits an unauthorized individual from accessing water from a water system device, such as a fire hydrant. The transmitter transmits a first signal when the water system protection device is tampered with. One or more sensing devices are provided that sense when the water system protection device has been tampered with, and cause the transmitter to transmit the first signal. The transmitter may also transmit a normal operation signal indicating that the water system protection device has not been tampered with. The first signal may be encrypted. The first signal may indicate the location of the water system device. An alarm, located at or near the water system device, may be activated when the water system protection device is tampered with.

Abstract: An apparatus is disclosed comprising a first cover and an attachment device to which the first cover is connected, wherein the attachment device can be used to attach the first cover to a fire hydrant such that the first cover covers the first nozzle cap. The apparatus may also be comprised of second and third covers which are also attached to the attachment device and which can be used to cover second and third nozzle caps of the fire hydrant. The attachment device may be comprised of a first portion, the first portion substantially in the form of a ring. The attachment device may be comprised of a second portion, and the second portion can be connected to the first portion so that the first portion and the second portion provide a closed ring.
