Working through the COSMOD2W interface module, it sends separate smoke and CO signals to a conventional fire alarm panel and sounds Temporal 3 for smoke and Temporal 4 for CO. One device replaces separate smoke and CO detectors, cutting wiring and back boxes.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDistinct smoke and CO signals to the panel via the i4 interface module\u003c\/li\u003e\n\u003cli\u003eBuilt-in 85 dBA sounder with Temp 3 (smoke) and Temp 4 (CO) patterns\u003c\/li\u003e\n\u003cli\u003eField-replaceable CO cell with a 10-year end-of-life timer\u003c\/li\u003e\n\u003cli\u003eRealTest function allows a functional CO test with canned CO\u003c\/li\u003e\n\u003cli\u003ePlug-in base with EZ Walk loop testing and SENS-RDR sensitivity checks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSystem Sensor i4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWiring\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2-wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSensing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePhotoelectric smoke + electrochemical CO\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSmoke sensitivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.5%\/ft nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e12\/24 VDC nominal (8.5–35 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax. standby current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 µA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax. alarm current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSounder\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e85 dBA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e32–122°F (0–50°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHumidity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20–95% RH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5.5 in diameter × 2.5 in deep (with base)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e9.2 oz (261 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.5\/4 in octagonal, single-gang, 4 in square, round ceiling boxes, or direct to wall\/ceiling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eListings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUL 268, UL 2075\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eThe COSMOD2W 2-wire interface module is required to connect COSMO-2W detectors to a fire alarm panel; one module supports up to 12 compatible detectors.
