Analog Devices Inc. ADPD188BI-ACEZR7 Integrated Optical Modules are complete photometric systems for smoke detection using optical dual wavelength technology. The modules integrate a highly efficient photometric front end, two light emitting diodes (LEDs), and two photodiodes (PDs). The modules are housed in a custom package to prevent light from going from the LED to the photodiode without entering the smoke detection chamber.
Feature
Supports UL-217 edition 8/ UL-568 ed. 7; EN-54; GB..; ISO
Lowers Nuisance Alarms using a Dual Wavelength detection with higher SNR and dynamic range.
3X Lower power dissipation enables smaller/ cheaper batteries
Integrated Optical Module (3.8mm x 5mm x 0.9mm with 1 blue LED, 1 IR LED and 2 Photo diodes)
Loop calibration at final test reduces calibration challenges with smoke detector products.
Supported by ADI designed smoke chamber manufactured by Accumold, 28800X. (Please see , also under Resources below)
