This datasheet contains PROPRIETARY and CONFIDENTIAL information.
General Description
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.
