AC Ionization Smoke Detector With Interconnect And Timer

The A5349 is a low-current, CMOS circuit providing all of the required features for an ionization-type Smoke detector A networking capability allows as many as 125 units to be interconnected so that if any unit senses smoke all units will sound their alarm. In addition, special features are incorporated to facilitate alignment and test of the finished Smoke detector
The internal Oscillator and Timing circuitry keep standby power to a minimum by powering down the device for 1.66 seconds and sensing for smoke for only 10 ms. Every 24 on-off cycles, a check is made for a low supply condition. By substituting other types of Sensors or a Switch for the ionization detector, this very-lowpower device CAN be used in numerous other safety/security applications.
