NON-METALLIC ALERT SYSTEMS
First Claim
1. An alert system for alerting to a disturbance of a protected component, the system comprising:
- a signal transmitter for providing a signal;
a receiver for receiving the signal;
a relay coupled to receiver, and being triggered when the receiver does not receive the signal;
a non-metallic communication cable for propagating the signal from the signal transmitter to the receiver, the non-metallic communication cable being attached to a protected section of the protected component, wherein removal of the protected section damages the non-metallic communication cable and causes an interruption in the signal, and wherein the relay is triggered in response to the signal interruption; and
an alert device activated in response to the relay being triggered.

Abstract
Alert systems indicate removal of one or more protected portions of electrical grounding assemblies. An alert system can include a signal transmitter, a signal receiver, an alert device, and a communication cable. The signal transmitter can transmit a signal to be received by the signal receiver. The alert device can be coupled to the signal receiver, such that the alert device is activated when the signal is not received. A non-metallic communication cable can propagate the signal from the signal transmitter to signal receiver. The communication cable can be bound to a protected portion of the grounding assembly, such that disturbance of the protected portion can damage the communication cable. Because damage to the communication cable can cause an interruption in the signal, such damage can result in activation of the alert device. Accordingly, disturbance of the protected portion of the grounding assembly can activate the alert device.

10. An alert system comprising:
-
a circuit comprising; a signal transmitter for transmitting a signal; a receiver for receiving the signal; a non-metallic communication cable for conveying the signal from the signal transmitter to the relay; a relay remaining de-energized while the receiver receives the signal; and an alert device powerable by the relay when the relay is energized; wherein the non-metallic communication cable of the circuit is bound to a protected portion of a grounding assembly, and removal of the protected portion damages the non-metallic communication cable, thereby interrupting the signal. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An alert system for alerting to removal of a protected component of a grounding assembly, the system comprising:
-
a black box device comprising; an output pin for transmitting a signal; and an input pin for receiving the signal; a relay couplable to the black box device, and energizable when the input pin of the black box device does not receive the signal; an alert device activatable by the relay when the relay is energized; and a non-metallic communication cable for passing the signal from the output pin of the black box device to the input pin of the black box device, the non-metallic communication cable being bound to the protected section of the grounding assembly; wherein separation of the protected section from the grounding assembly damages the non-metallic communication cable, such that the signal does not reach the input pin of the black box device and the relay is triggered. - View Dependent Claims (18, 19, 20)
