Description

The MC145017, when used with an ionization chamber and a small number of external components, will detect smoke. When smoke is sensed, an alarm is sounded via an external piezoelectric transducer and internal drivers. MC145017 is designed to operate in smoke detector systems that comply with UL217 and UL268 specifications.
