Abstract
The invention provides a self-contained automatic fire detection, warning, and suppression life safety system having an extinguishant source and a fire detector coupled to an electronic processor. The processor has logic to interface with components for detecting and warning of a fire and releasing the extinguishant. Self-diagnosis logic checks the entire system's function, pressure, power level, and power source. Additional sensors are provided for detecting various hazards, and the processor has logic for proper response.
Claims12
An automatic fire detection and suppression system, comprising:
- a vessel for containing a fire extinguishant under pressure;
- a dip tube assembly sealingly engaged within an opening of the vessel, the assembly including a dip tube with one end extending inside the vessel and the other end being external to the vessel;
- a solenoid valve having an inlet and an outlet, the inlet being connected to the other end of the dip tube, the valve being normally closed;
- a nozzle assembly connected to the outlet, the nozzle assembly including a discharge nozzle for discharging extinguishant;
- a circuit board coupled to the solenoid valve;
- a housing for receiving the circuit board;
- a microprocessor received on and coupled with the circuit board;
- and
- a heat sensor and an ionic smoke sensor coupled to the microprocessor for sensing heat and/or smoke, wherein the microprocessor has logic for detecting heat or smoke, logic for calculating a rate of rise or for comparing to an ionic smoke density formula for determining the presence of a fire, and logic for opening the solenoid valve when the presence of a fire is determined so that the extinguishant is released to suppress the fire.
