Multistandard Micropower Verified Smoke Detection System-on-Module

View Detailed Reference Design

Features and Benefits

The CN0583 reference design plus related software is designed and tested to meet UL 217 8th edition, EN14604:2005, and similar smoke/fire detection standards. To address the needs of different customers, a number of solution offerings are available which are summarized in the table below. ​

The hardware is designed to accelerate prototyping and the evaluation of the embedded smoke detection algorithm. The hardware is comprised of the EVAL-CN0583-SOM and EVAL-CN0583-CRR1 Carrier Board.​

The Data package (ADSW-SMOKEDATA-PRODLIC) provides an extensive (1000+) smoke dataset taken at UL 217 and EN14604 certified facilities for those who wish to develop their own algorithm. It includes the CN0583 source code for initialization, calibration, environmental compensation, data pre-processing - but excludes the detection algorithm.​

The Algorithm package (ADSW-SMOKEDATA-PRODLIC) includes everything in the Data package and adds UL & EN validated smoke detection algorithm and associated algorithm project files.

  • Complete Smoke Detector System on Module
  • Micropower Operation for >10 Year Battery Lifetime
  • UL 217 & UL 268 Verified Smoke Detector Algorithm
  • EN 54-7 & EN 14604 Verified Smoke Detector Algorithm
