RE46C126

The RE46C126 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. . A 2/3 duty cycle continuous horn pattern is used for the alarm condition. An interconnect pin allows multiple detectors to be connected such that when one unit alarms all units will sound. Although this device was designed for smoke detection utilizing an ionization chamber it can be used in a variety of security applications. Utilizing low power CMOS technology the RE46C126 was designed for use in smoke detectors that comply with Underwriters Laboratory Specification UL217 and UL268
