1. A protective device for preventing tampering with a fire control system in a building, the fire control system for transmission of a flow of a fluid from an upstream end of the fire control system 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 between the upstream and downstream ends;
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 through the pipe insert, and the closed position occludes the pipe insert, disabling transmission of the flow of the fluid through the pipe insert to the downstream end of the fire control system; and
a sensor for disposition within the flow of the fluid to detect a target compound in the pipe insert;
wherein the valve moves from the open position to the closed position when the sensor detects the target compound.
