System Sensor COSMO-2W i4 Series, 12/24V, 2-Wire, System-Connected, Combination Carbon Monoxide/Smoke Detector with RealTest Technology

Protect occupants and property with a single System Sensor solution that combines reliable smoke and carbon monoxide detection while simplifying installation and monitoring. The COSMO-2W i4 Series combination CO/smoke detector uses photoelectric and electrochemical sensing to detect smoke and CO early, and its 2‑wire, system‑connected design (12/24V compatible) lets integrators add up to 12 devices to an i4 loop for centralized alarm reporting. Built‑in 85 dB sounder and distinct smoke vs. CO signaling ensure clear on‑site notification while panels receive precise event information for fast response. RealTest technology and an external IR LED streamline sensitivity testing and routine maintenance, supporting ongoing surveillance and monitoring programs. UL listed for dependable performance, the COSMO-2W is ideal for multifamily, retail and light‑commercial environments where safety, reduced wiring, and compatibility with fire alarm control panels matter. Upgrade your security and life‑safety system with a compact, code‑ready combo detector—order the System Sensor COSMO-2W today for reliable monitoring and peace of mind.
