The smoke detector has a signal unit (10a,12a,14a,16a) to send and receive electromagnetic radiation. A signal guidance unit (18a,20a,22a,24a) is arranged in the path of rays (26a,28a,30a,32a) of the signal unit. An actuator unit (88a,90a,92a,94a) is provided which coordinates with signal guidance unit. The signal guidance unit is designed as optical filter (36a,38a) which identifies carbon mono-oxide. |
