The CXSD2211 is a low power, low voltage photoelectric type smoke detector IC. With
minimal external components, this circuit will provide all the required features for a photoelectric-type
smoke detector.A check for a low battery condition is performed every 86 seconds, and chamber
integrity is tested once every 43 seconds, when in Standby. The temporal horn pattern supports the
NFPA 72 emergency evacuation signal.
The CXSD2211 incorporates a gain-selectable photo amplifier for use with an infrared emitter/detector
pair.An internal oscillator strobes power to the smoke detection circuitry every 10 seconds, to keep the 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.An internal 9 minute
timer can be used for a Reduced Sensitivity mode.An interconnect pin allows multiple detectors to be connected
such that, when one unit alarms, all units will sound.
