Future MicroSIR Sensor Technology

The new MicroSIR Sensor housing shown in Figure 2 is similar in design to the SIR sensor. The housing protects the sensing elements from physical damage and harm. A filter (getter) and retainer clip hold the sensing elements in place and prevent dust, smoke particles, liquid water, and other chemicals from entering the sensor chamber. The SIR sensing elements are held in optical alignment by the sensor housing placed between an infrared light emitting diode (LED) and a photodiode.

Only Quantum Sensor Technology (available in the COSTAR® carbon monoxide alarms) gives reliable protection without false alarms. Electrochemical and metal oxide semiconductor CO sensors — used in most competitors’ detectors — are sensitive to many common household gases, particularly from cleaning products and air fresheners. Their frequent false alarms can lead people to ignore valid alerts, with fatal results.

COSTAR® alarms, on the other hand, react only to the presence of carbon monoxide gas, and will not be affected in normal operation to other gasses found in a typical household during its 6 year life.
