Claim 14:
15. A protective device for preventing transmission of a target compound in a flow of a fluid within a pipe in a fire control system in a building from an upstream end of the fire control system at a fire department connection outside the building to a downstream end of the fire control system at sprinklers within the building, the protective device comprising:
a pipe insert, disposed within the fire control system, wherein the pipe insert has an upstream side and a downstream side;
a valve within the pipe insert, the valve moveable between open and closed positions, wherein the open position opens the pipe insert, enabling transmission of the flow of the fluid from the upstream side to the downstream side, and the closed position occludes the pipe insert, disabling transmission of the flow of the fluid from the upstream side to the downstream side;
a sensor within the pipe insert for disposition within the flow of the fluid and configured to detect a target compound in the pipe insert; and
a computer coupled to the sensor in data communication for processing readings from the sensor and transmitting a detection signal to the valve in response to detecting the target compound in the pipe insert; wherein
the valve moves from the open position to the closed position in response to receiving the detection signal.
