Assignee:
Kidde Technologies, Inc. - Wilson NC
International Classification:
A62C 37/10
US Classification:
169 61, 169 60, 174 72 A
Abstract:
A fire extinguishing system includes a first data bus having respectively first power and command leads. The system has multiple zones, each of which may include one or more detectors, and/or one or more suppressors and activation devices. The first data bus is directly connected and common to the detectors, suppressors and activation devices. A controller is connected to the multiple zones via the first data bus. A fire activation module includes the actuation device. First and second power leads are connected to the actuation device. A capacitor is connected to the actuation device and the power leads. The capacitor is configured to store electricity from the power leads and discharge the electricity to the actuation device during a suppression event. A wiring harness provides a zone identification element in communication with a connector and configured to provide a zone location assignment to the connector.

Assignee:
Hamilton Sundstrand Corporation - Windsor Locks CT
International Classification:
A62C 37/40
US Classification:
169 61, 169 56
Abstract:
A fire activation module for a fire extinguishing system includes an actuation device that has an instantaneous actuation current draw during a suppression event. First and second power leads are connected to the actuation device and have a current capacity less than the instantaneous actuation current draw. At least one capacitor is connected to the actuation device and the power leads. The capacitor is configured to store electricity from the power leads and discharge the electricity to the actuation device during the suppression event.

Fiber Optic Flame And Overheat Sensing System With Self Test
View pageUS Patent:
50642715, Nov 12, 1991
Filed:
Mar 14, 1989
Appl. No.:

International Classification:
G02B 602
G02B 616
G02B 616
US Classification:
385 33
Abstract:
A fiber optic fire and overheat sensor system 10 includes a fiber optic cable 12 having a lens 14 at a distal to direct radiation from a fire 16 into the cable 12 and to a radiation detector 18 disposed at a proximal end of the cable 12. Detector 18 is coupled to a fire sensor 19. The detector 18 is sensitive to two wavelength bands including a short wavelength band of approximately 0. 8 to approximately 1. 1 microns and a long-wavelength band of approximately 1. 8 to approximately 2. 1 microns. A controller 21, such as a microprocessor, analyzes the fire sensor 19 output signals which correspond to the two spectral bands to determine if a fire is present. The system 10 further includes a body of fluorescent material 20 disposed at the distal end of the cable 12. The material 20 can be interposed between a reflecting surface, such as a mirror 22, and a lens, such as a collimating lens 24. A fiber optic coupler 26 and 26a launches radiation from a source 28, such as a laser diode, into the fiber optic cable 12.

US Classification:

Abstract:
A fiber optic fire detection and temperature measurement system 10 includes a fiber optic cable 12 having a lens 14 at a distal to direct radiation from a fire 16 into the cable 12 and to a radiation detector 18 disposed at a proximal end of the cable 12. Detector 18 is coupled to a fire sensor 20. The detector 18 is sensitive to three wavelength bands including a short wavelength band of approximately 0. 8 to 1. 1 microns and a long-wavelength band of approximately 1. 8 to 2. 1 microns. A controller 22, analyzes the fire sensor 20 output signals which correspond to the two spectral bands to determine if a fire is present. The fiber optic conductor of cable 12 includes an optical filter 32 having a temperature dependent radiation transmission characteristic. Radiation from a fire passes via cable 12 to the detector 18. A dual wavelength pulse of radiation from a source 28 passes through the filter 32 where a reference wavelength, corresponding to one of the fire sensor spectral bands, passes through unimpeded while the other wavelength within a third spectral band is absorbed as a function of temperture.

Abstract:
A fiber optic fire detection and temperature measurement system 10 includes a fiber optic cable 12 having a lens 14 at a distal to direct radiation from a fire 16 into the cable 12 and to radiation detector 18 disposed at a proximal end of the cable 12. Detector 18 is coupled to a fire sensor 20. Detector 18 is sensitive to three wavelength bands including a short wavelength band of approximately 0. 8 to 1. 1 microns, a mid-wavelength band of approximately 1. 3 to 1. 5 microns and a long-wavelength band of approximately 1. 8 to 2. 1 microns. A controller 22, analyzes the fire sensor 20 output signals which correspond to the two spectral bands to determine if a fire is present. The fiber optic conductor is doped with a material selected for its temperature dependent fluorescent emission characteristics. Radiation from a fire passes via cable 12 to the detector 18. A pulse of radiation from source 28 passes from a coupler 26 and 26a to the cable 12.
