Analog Devices Announces UL 217 Tested and Verified Smoke Detector Reference Design and Algorithm

by donpedro

Analog Devices, Inc. (ADI) introduced today a reference design and algorithm that enables small form factor, low power, smoke detector designs to be rapidly prototyped and brought to market faster at a reduced cost. The new CN0537 reduces design risk and has been tested and verified to pass the UL 217 Standard for Smoke Alarms, 8th edition. The reference design uses Analog Devices’ ADPD188BI high performance optical sensor core combined with precision smoke chamber for reduced nuisance alarms.
