Sensor and Detector Interface 12V 16Pin SOIC W Tape and Reel
General Description
The RE46C141 is 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 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 every 32 seconds when in standby. The temporal horn pattern supports the NFPA 72 emergency evacuation signal.
