Abstract

Fire protection systems and methods for ceiling-only high-piled storage protection. The systems and methods include a fluid distribution, detection and control sub-systems to identify one or more fluid distribution devices for controlled operation to address a fire.

First claim

What is claimed is:

1. A system, comprising:
a plurality of fluid distribution devices;
at least one detector that outputs an input signal indicative of a fire, each fluid distribution device of the plurality of fluid distribution devices associated with a corresponding detector of the at least one detector; and
a controller comprising one or more processors to:
receive the input signal from the at least detector;
determine, based on the input signal, that a first threshold has been met or exceeded;
identify at least one fluid distribution device of the plurality of fluid distribution devices associated with the at least one detector for which the input signal is determined to indicate that the first threshold has been met or exceeded;
assign the identified at least one fluid distribution device to a queue, wherein the controller has a minimum number for fluid distribution devices to be assigned to the queue before actuation of the identified at least one fluid distribution device and has a maximum number of fluid distribution devices in the queue to limit fluid distribution devices to be operated by the controller;
determine, based on the input signal, that a second threshold has been met or exceeded, the second threshold higher than the first threshold; and
actuate at least the minimum and up to the maximum number of fluid distribution devices assigned to the queue responsive to determining that the second threshold has been met or exceeded and that the minimum number of fluid distribution devices of the plurality of fluid distribution devices are assigned to the queue.

2. The system of claim 1 , comprising:
the plurality of fluid distribution devices are coupled with one or more pipes below a ceiling of a building and above a storage commodity in the building, a height of the ceiling is greater than thirty feet.

3. The system of claim 1 , comprising:
the at least one detector comprises a plurality of detectors, and each fluid distribution device of the plurality of fluid distribution devices is associated with a single detector of the plurality of detectors.

4. The system of claim 1 , comprising:
the controller determines a location of the fire using the input signal.

5. The system of claim 1 , comprising:
the first threshold and the second threshold correspond to at least one of a temperature and a rate of rise of temperature.

6. The system of claim 1 , comprising:
the plurality of fluid distribution devices are in a ceiling-only arrangement.

7. The system of claim 1 , comprising:
the at least one detector provides the input signal based on at least one of temperature, thermal energy, and spectral energy.

8. The system of claim 1 , comprising:
the at least one detector is axially aligned with at one or more fluid distribution devices of the plurality of fluid distribution devices.

9. The system of claim 1 , comprising:
the plurality of fluid distribution devices are positioned over a stored commodity comprising at least one of a Group A plastic, a Group B plastic, and a Group C plastic.

10. A method, comprising:
receiving, by one or more processors, an input signal indicative of a fire from at least detector; determining, by the one or more processors based on the input signal, that a first threshold has been met or exceeded;
identifying, by the one or more processors, at least one fluid distribution device of a plurality of fluid distribution devices associated with the input signal determined to indicate that the first threshold has been met or exceeded;
assigning, by the one or more processors, the identified at least one fluid distribution device to a queue, wherein a controller has a minimum number for fluid distribution devices to be assigned to the queue before actuation of the identified at least one fluid distribution device and has a maximum number of fluid distribution devices in the queue to limit fluid distribution devices to be operated by the one or more processors;
determining, by the one or more processors based on the input signal, that a second threshold has been met or exceeded, the second threshold higher than the first threshold;
and actuating, by the one or more processors, at least the minimum and up to the maximum number of fluid distribution devices assigned to the queue responsive to determining that the second threshold has been met or exceeded and that a minimum number of fluid distribution devices of the plurality of fluid distribution devices are assigned to the queue.

11. The method of claim 10 , comprising:
the plurality of fluid distribution devices are coupled with one or more pipes below a ceiling of a building and above a stored commodity in the building, a height of the ceiling is greater than thirty feet.

12. The method of claim 10 , comprising:
each fluid distribution device of the plurality of fluid distribution devices is associated with a particular detector of a plurality of detectors, each detector of the plurality of detectors providing the input signal.

13. The method of claim 10 , comprising:
determining, by the one or more processors, a location of the fire using the input signal.

14. The method of claim 10 , comprising:
the first threshold and the second threshold correspond to at least one of a temperature and a rate of rise of temperature.

15. The method of claim 10 , comprising:
the plurality of fluid distribution devices are in a ceiling-only arrangement.

16. The method of claim 10 , comprising:
receiving, by the one or more processors, the input signal based on at least one of temperature, thermal energy, and spectral energy.

17. The method of claim 10 , comprising:
receiving, by the one or more processors, the input signal from at least one detector that is axially aligned with one or more fluid distribution devices of the plurality of fluid distribution devices.

18. The method of claim 10 , comprising:
the plurality of fluid distribution devices are positioned over a stored commodity comprising at least one of a Group A plastic, a Group B plastic, and a Group C plastic.
