CMOS Ionization Smoke Detector ASIC With Interconnect And Timer Mode

The RE46C122 is low power CMOS ionization type Smoke detector IC. With few external components this circuit will provide all the required features for an ionization type Smoke detector An internal Oscillator strobes power to the smoke detection circuitry for 10.5mS every 1.66 seconds to keep standby current to a minimum. A check for a low battery condition is performed every 40 seconds when in standby. The temporal horn pattern supports the NFPA 72 emergency evacuation signal. An interconnect pin allows multiple detectors to be connected such that when one units alarms all units will sound. An internal 10 minute Timer allows for a separate button to be used for reduced sensitivity mode. Although this device was designed for smoke detection utilizing an ionization chamber it could be used in a variety of security applications. Utilizing low power CMOS technology the RE46C122 was designed for use in Smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268. By R&E International, Inc.
