Microchip announces the industry’s first Ion and photo smoke-detector ICs to offer alarm memory. The low-power power RE46C162 /3 Ion and RE46C165 /6/7/8 (RE46C16X) photo smoke-detector ICs make it easy to quickly determine which detector in an interconnected loop triggered an alarm. The ICs’ low energy use enables smoke detectors with a battery life of 10 years, and an interconnect filter enables a connection to other devices, such as CO detectors. When an alarm is falsely triggered, also known as “nuisance tripping,” it is difficult to determine which smoke detector set off the alarm.
The alarm-memory feature available on the RE46C16X ICs enables the detector that caused the fault to be easily identified, which greatly reduces costs associated with installing and troubleshooting these types of smoke-detector systems.
