    external components, this circuit will provide all the
    required features for a photoelectric-type smoke
    detector. Two AA Battery Operation
    Internal Power On Reset
    Low Quiescent Current Consumption
    Available in 16L N SOIC
    Local Alarm Memory
    Interconnect up to 40 Detectors
    9 Minute Timer for Sensitivity Control
    Temporal or Continuous Horn Pattern
    Internal Low Battery and Chamber Test
    All Internal Oscillator
    Internal Infrared Emitter Diode (IRED) driver
    Adjustable IRED Drive current
    Adjustable Hush Sensitivity
    2% Low Battery Set Point The design incorporates a gain-selectable photo
    amplifier for use with an infrared emitter/detector pair.
    An internal oscillator strobes power to the smoke ...
