Photoelectric Multisensing Technology
SD Series optical smoke detectors and multisensors

 

 

 

SD Series optical smoke detectors are engineered to meet strict UL fire safety codes and effectively respond to a wide spectrum of fires. The SD series multisensors use Photoelectric Technology in conjunction with a fixed temperature heat sensor to further extend its capabilities as reliable smoke detector. SD series detectors are manufactured and tested according to ISO9001: 2000 procedures.
