GST C-9102 Conventional Photoelectric Smoke Detector is non-addressable. Used together with end of line unit, it can connect with compatible control panels to process detection signals. It shows fire alarm by LED indicators and transmits the fire signal to the control panel. Using infrared scattering technology, the smoke density can be detected. The detector receives very weak infrared light under normal smokeless condition. If smoke particles enter the chamber, the received light signal will increase by scattering. When smoke density reaches a pre-set level, the detector will alarm out.

Kidde Airsense 30671 Stratos-Micra 25 is intended to provide LOCALISED incipient fire detection only. This means that it is suitable for the substantial range of applications typified by small non-compartmentalised rooms, warehouse racking, or pieces of electronic or electromechanical equipment where it is desirable to achieve individual incipient fire reporting. In compartmentalised rooms, each compartment would normally use individual Stratos-Micra 25 detectors.
