FULLY-INTEGRATED SMOKE DETECTOR REDUCES FALSE ALARMS

With the introduction of the ADPD188BI, Analog Devices (ADI) kills two birds with one stone: First, this smoke detector meets the latest international regulatory standards. Second, the device that integrates two LEDs, photodiode, and analog front-end (AFE) in a single package, help reduce false alarms often caused by steam and dust.

The ADPD188BI is engineered to meet new UL217 requirements as well as EN54/14604 specifications. Its integrated design uses two colors to separate particle sizes, increasing the ability to detect and classify smoke types and reject nuisance sources. The ADI solution enables a back-scattering design with closer proximity of the LED to the photodiode, reducing circuit board size and allowing for smaller smoke detectors that are more architecturally compatible for residential and commercial use.
