Still, the SC501CN's performance earns the highest possible grade both when it comes to smoldering fires, and as a CO detector. It receives top ratings across the board for detecting high concentrations of CO, low concentrations of CO and the quality of its alerts. The Kidde KN COSM BA Est. $35 is also worth considering. This combination smoke and CO alarm has been around for a number of years, and was previously known as the Kidde KN COSM B. It has two key differences compared to the SCO501CN 3ST: It is a stand alone detector that does not communicate with other alarms and the smoke detector uses ionization, not photoelectric technology. It has a voice annunciator that will identify the type of hazard fire or CO, but can't relay that to other detectors. It's not been professionally reviewed, but there's a large body of mostly satisfied users that post feedback at Amazon, where its overall score is 4. 4 stars following around 1,750 reviews. The Kidde KN COSM IBA Est. $40, previously known and sometimes still available as the Kidde KN COSM IB, is the hardwired version of the Kidde KN COSM BA but one with a significant difference: It can interconnect with up to 24 Kidde alarms plus an additional six sounding devices.

, and/or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document. The memory 406 includes high speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid state memory devices; and, optionally, includes non volatile memory, such as one or more magnetic disk storage devices, one or more optical disk storage devices, one or more flash memory devices, or one or more other non volatile solid state storage devices. The memory 406, or alternatively the non volatile memory within the memory 406, includes a non transitory computer readable storage medium. In some implementations, the memory 406, or the non transitory computer readable storage medium of the memory 406, stores the following programs, modules, and data structures, or a subset or superset thereof: operating logic 420 including procedures for handling various basic system services and for performing hardware dependent tasks;a device communication module 422 for connecting to and communicating with other network devices e. g. , network interface 160, such as a router that provides Internet connectivity, networked storage devices, network routing devices, server system 164, etc. connected to one or more networks 162 via one or more communication interfaces 404 wired or wireless;an input processing module 426 for detecting one or more user inputs or interactions from the one or more input devices 414 and interpreting the detected inputs or interactions;a user interface module 428 for providing and displaying a user interface in which settings, captured data, and/or other data for one or more devices e. g. , the smart device 204, and/or other devices in smart home environment 100 can be configured and/or viewed;one or more applications 430 for execution by the smart device e. g. , games, social network applications, smart home applications, and/or other web or non web based applications for controlling devices e.
