www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC146010 Rev 0, 09/2005 Low Power CMOS Photoelectric Smoke Detector IC The MC146010 is an advanced smoke detector component containing sophisticated very-low power analog and digital circuitry.

The IC, when used with an infrared photoelectric chamber and a small number of external components, will detect smoke by sensing scattered light from smoke particles.

When detection occurs, a pulsating alarm is sounded via on-c
