Definitions
- the disclosure relates to a life safety device for detecting one or more conditions, such as smoke and carbon monoxide for example. More specifically, the disclosure relates to a life safety device having an easily accessible and replaceable carbon monoxide sensor.
- Carbon monoxide poisoning has increase dramatically in recent years. Carbon monoxide is a colorless, odorless, tasteless gas, making it virtually undetectable to a human. Carbon monoxide can be produced by various fuel burning appliances, such as, fuel fired furnaces, gas hot water heaters, gas stoves, gas dryers, space heaters, charcoal grills, fireplaces, vehicles, lawn mowers, or snow blowers. Once present, this gas circulates freely throughout a building, such as a home. If this gas is not ventilated properly, carbon monoxide poisoning may result.

- With reference now to
FIG. 1 , a schematic view an embodiment of afire detection system 10 is illustrated. Thefire detection system 10 maybe part of afire loop 12, such as located within a building or a portion of a building for example. As shown, thesystem 10 includes a plurality ofdevices 14 arranged in an array 16 in thebuilding 12. All or a portion of thedevices 14 are configured to detect fire, smoke and/or other properties in the area near the fire device's location within the array 16. Examples of suitable fire devices include but are not limited to detectors, sounders, beacons, remote indicators, and input/output modules for example. Thedevices 14 are connected to acentral control panel 18, such as a fire alarm control panel (FACP). In some embodiments, thefire detection system 10 is connected with, for example, a fire alarmcontrol panel network 20 to communicate a status of thefire detection system 10 and/or sound an alarm in the case of a fire. Althoughsystem 10 is described with reference to detection of a fire, it should be understood that thesystem 10 and the device 14s therein may be adapted for detection of a variety of hazardous conditions, including but not limited to smoke, carbon monoxide, explosive gas, and heat for example. - Referring now to
FIG. 2 , a partial cross-sectional view of an example of one of thedevices 14 of thefire detection system 10 is illustrated. Thedevice 14 includes ahousing 21 formed from abase 22 fixed to a portion of thebuilding 12 and areplaceable device 24 installed to and connected to thebase 22. As previously described, thedevice 14 is arranged in communication with thecontrol panel 18. In an embodiment, thedevice 14 includes a processor orcontroller 28 configured to send information to and receive information from thecontrol panel 18. Further, unique information associated with eachspecific device 14, such as an address and/or other information, may be utilized by thecontrol panel 18 to define the location of thedevice 14 in the array 16 and to facilitate communication between thecontrol panel 18 and thedevice 14. In an embodiment, this unique information may be stored within a database accessible by thecontroller 28. Alternatively, thedevice 14 may include anidentification tag 26 configured to transmit information to thecontrol panel 18 independently of the controller. - Further, while the discussion herein refers to a
controller 28, one skilled in the art will recognize that the functionality and intelligence associated with this element may be alternatively embodied in a microprocessor with associated input/output and buffering circuits, in a programmable logic device (PLD), in an application specific integrated circuit (ASIC), or other intelligent, programmable device. Therefore, the use of the term microcontroller herein shall be construed to cover all of these alternative structures as well. - With reference now to
FIGS. 3 and4 , an example of a portion of various types ofdevices 14 is shown. InFIG. 3 , an example of thebase 22 of a first type ofdevice 14, such as a fire detector for example, is shown. A second type ofdevice 14 is illustrated inFIG. 4 . In the illustrated, non-limiting embodiment, the second type ofdevice 14 is a remote indicator. Within a system, such asfire detection system 10 for example, a remote indicator is configured to indicate to a nearby person the status of anon-visible device 14. Thedevices 14 illustrated herein are intended as an example only, and anysuitable device 14 within afire detection system 10 is contemplated herein. - A device or sensor for measuring a level of
carbon monoxide 30 adjacent thedevice 14 may be integrated into a portion of thedevice 14. In the illustrated, non-limiting embodiment, thecarbon monoxide device 30 is a carbon monoxide sensor; however it should be understood that anysuitable device 30 is within the scope of the disclosure. Further, the device is shown as being integrated into thebase 22 of thedevice 14. However, embodiments where thecarbon monoxide sensor 30 is integrated into another portion of thefire device 14, such as within thereplaceable portion 24 for example, are also contemplated herein. - Regardless of the type of
fire device 14, thecarbon monoxide device 30 may be positioned such that a sensing portion of thedevice 30 is exposed to or is arranged in fluid communication with the ambient air or the environment external to thedevice 14. In an embodiment, best shown inFIG. 5 , thecarbon monoxide device 30 is located within a pocket orcavity 32 formed in thebase 22. The contours of thecavity 32 or area where thecarbon monoxide device 30 is located may be designed to ensure that thecarbon monoxide sensor 30 is correctly positioned for optimal sensing. A movable flap orpanel 34 may be located at the exterior of the base 22 adjacent thecavity 32 to selectively provide a user with access to thecarbon monoxide device 30 disposed therein. - A
device 14 having a device for sensing the presence ofcarbon monoxide 30 integrated into or embedded within the base 22 functions in a manner similar to conventional devices where a carbon monoxide sensor is mounted to the circuit board orcontroller 28 of thedevice 14. With reference toFIG. 6 , thecarbon monoxide device 30 may be configured to provide an input to theprocessor 28. If thecontroller 28 determines that the input from thedevice 30 exceeds an allowable threshold, thecontroller 28 will communicate this information with theFACP 18, which will then activate an alarm, illustrated schematically at 40, associated with thefire detection system 10 through theFACP network 20. - By positioning the
carbon monoxide device 30 within the housing of thedevice 14, and more specifically within thebase 22, the exposure to of thedevice 30 to the environment is increased, thereby enhancing the detection efficiency of thedevice 14. Further, because thecarbon monoxide device 30 is mounted within thebase 22, and not to another component buried within the interior of thedevice 14, thecarbon monoxide device 30 may be easily accessed and replaced upon determination that thedevice 30 has malfunctioned. Accordingly, the functionality ofdetectors 14 that are commonly used for other types of monitoring may be increased. - While the disclosure has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the disclosure is not limited to such disclosed embodiments. Rather, the disclosure can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the disclosure. Additionally, while various embodiments of the disclosure have been described, it is to be understood that aspects of the disclosure may include only some of the described embodiments. Accordingly, the disclosure is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
