The RE46C143 is low power CMOS photoelectric type smoke detector IC.

for a photoelectric type smoke detector. The design incorporates a gain selectable photo amplifier for use with an infrared emitter/detector pair. An internal oscillator strobes power to the smoke detection circuitry for 100us every 8.1 seconds to keep standby current to a minimum. If smoke is sensed the detection rate is increased to verify an alarm condition. A high gain mode is available for push button chamber testing. A check for a low battery condition and chamber integrity is performed ev.
