Conventional Detection
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.
