Non-permissive fire connection system

A non-permissive fire connection system, wherein the non-permissive fire connection system comprises:

• a hydrocarbon detection sensor and an electronic shut-off valve integrated in the non-permissive fire connection system;
• said hydrocarbon detection sensor calibrated to detect a hydrocarbon in a hydrocarbon fuel that flows via a fire department connection line into a building;
• said electronic shut-off valve configured to instantly respond to an electrical signal from the hydrocarbon detection sensor, wherein the electronic shut-off valve shuts off flow of the hydrocarbon fuel via the fire department connection line into a riser line and a sprinkler system, when the hydrocarbon detection sensor generates an electrical signal upon detecting the hydrocarbon in the fire department connection line, thereby precluding flow of the hydrocarbon fuel into the riser line and the sprinkler system of the building;
• a hardwired power supply system with a built-in battery backup, wherein the non-permissive fire connection system connects directly to a power grid of the building, and wherein in an event of power loss, the built-in battery backup ensures that the non-permissive fire connection system remains operational;
• and
• a fail-safe logic circuit that detects one or more of an error state or an error condition or a compromised condition of the non-permissive fire connection system, and defaults the electronic shut-off valve to a closed state.

A non-permissive fire connection system, wherein the non-permissive fire connection system comprises:

• a sensor assembly, a first electronic shut-off valve, a hydrocarbon detection sensor and a second electronic shut-off valve integrated within the non-permissive fire connection system, wherein the sensor assembly and the first electronic shut-off valve are installed upstream of the hydrocarbon detection sensor, such that a liquid entering a fire department connection line passes through the sensor assembly and the first electronic shut-off valve before reaching the hydrocarbon detection sensor;
• wherein said sensor assembly is calibrated to detect physical properties comprising pressure, density, and viscosity of the liquid entering the fire department connection line, wherein said sensor assembly comprises a pressure sensor, a density sensor, and a viscosity sensor;
• wherein said first electronic shut-off valve is configured to shut off flow of the liquid into the fire department connection line, when the incoming liquid flowing into the building is contaminated with a hydrocarbon;
• said hydrocarbon detection sensor calibrated to detect the hydrocarbon that flows into a sprinkler system within a building via the fire department connection line and a riser line;
• said second electronic shut-off valve configured to instantly respond to an electrical signal from the hydrocarbon detection sensor, wherein the second electronic shut-off valve shuts down flow of the incoming liquid into the fire department connection line, the riser line, and the sprinkler system, when the hydrocarbon detection sensor senses the hydrocarbon in the liquid flowing along the fire department connection line, thereby precluding flow of the hydrocarbon fuel into the riser line and the sprinkler system of the building;
• a hardwired power supply system with a built-in battery backup, wherein the non-permissive fire connection system connects directly to a power grid of the building, and wherein in an event of power loss, the built-in battery backup ensures that the non-permissive fire connection system remains operational;
• and
• a fail-safe logic circuit that detects one or more of an error state or an error condition or a compromised condition of the non-permissive fire connection system, and defaults the electronic shut-off valve to a closed state.
