Description
The RE46C165/6/7/8 devices are low-power, CMOS
photoelectric type, smoke detector ICs. With minimal
external components, these circuits will provide all the
required features for a photoelectric type smoke
detector.
Each 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 100 s every 10 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 43 seconds when in
standby. The temporal horn pattern supports the
NFPA 72 emergency evacuation signal.
An interconnect pin allows multiple detectors to be
connected so when one unit alarms, all units will sound.
A charge dump feature will quickly discharge the
interconnect line when exiting a local alarm. The
interconnect input is also digitally filtered.
An internal timer allows for single button, push-to-test
to be used for a reduced sensitivity mode.
An alarm memory feature allows the user to determine
if the unit has previously entered a local alarm
condition.
Utilizing
low-power
CMOS
technology,
the
RE46C165/6/7/8 was designed for use in smoke
detectors that comply with Underwriters Laboratory
Specification UL217 and UL268.
