Model: CS12
CS12 Standalone Smoke And Carbon Monoxide Combo Alarm
The CS12 standalone smoke and carbon monoxide combo alarm uses a chamber and electrochemical sensor to detect smoke and carbon monoxide. Infrared light scattering picks up smoke particles, while gas diffusion into the CO sensor generates a current proportional to concentration, triggering the alarm. It is certified by TUV as an ordinary alarm and meets EN14604 and EN50291-1 standards.

The CS12 Standalone Smoke And Carbon Monoxide Combo Alarm monitors smoke and Carbon Monoxide by using a chamber and electrochemical sensor. The chamber utilizes infrared emission and reception technology. When there is no smoke in the environment, the receiver cannot receive infrared light; when there is smoke, smoke particles scatter infrared light, altering the receiver’s signal and triggering the alarm. Also, ambient air (containing carbon monoxide) slowly diffuses into the CO sensor through vents on the alarm casing. This generates an electric current: the reaction produces a tiny flow of electrons (current). The higher the concentration of carbon monoxide, the more molecules participate in the reaction, and the stronger the current produced. It is classified as an ordinary Alarm by TUV.
