Quantum Guardian®Advanced MicroSIR Sensor Technology
Figure 2 shows the new advanced MicroSIR Sensor housing. This polycarbonate housing protects the sensing elements from both physical damage and chemical contamination. A filter and getter system is used to protect the sensing elements. The filter blocks dust, smoke particles, liquid water, and other chemicals from entering the sensor chamber. The sensing elements are held in optical alignment by the sensor housing placed between an infrared light emitting diode (LED) and a photodiode.
Quantum carbon monoxide detection technology has been tested most reliable and it is the only technology to pass the interference gas testing by Lawrence Berkeley National Laboratory (LBNL) testing please see LBNL Report 40556. Electrochemical and metal oxide semiconductor CO sensors — used in most competitors’ detectors — are sensitive to many common household products such as wipes, detergence, insecticides, cleaners, air fresheners, alcohol, and disinfectants. Any false alarms can cause people to ignore the second alarm. Often the second alarm is real and people die!
Quantum Guardian® alarms react selectively, which means only to the presence of carbon monoxide gas, and not to household products.
