    Warnings Local Alarm Memory Interconnect up to 40 Detectors IO Filter and Charge Dump Smart IO for CO alarm Option 9-Minute or 80-Second Hush Timer Smart HushВ® Option Automatic Alarm Locate for Interconnected Units The RE46C200 is a next generation low power CMOS
    photoelectric-type smoke detector IC. With minimal
    external components, this circuit will provide all the
    required features for a photoelectric-type smoke
    The design incorporates a gain selectable photo
    amplifier for use with an infrared emitter/detector pair.
    An on-chip oscillator strobes power to the smoke
    detection circuitry for 5 ms every 10 seconds to keep
    standby current to a minimum.
    A check for a low battery condition is performed every
    80 seconds and chamber test is performed once every
    320 seconds when in standby. The temporal horn
    pattern supports the NFPA 72 emergency evacuation
    An interconnect pin allows multiple detectors to be
    connected such that when one unit alarms, all units will
    sound. A charge dump feature will quickly discharge
    the interconnect line when exiting a local alarm. The ...
