Descriptions
Fire-alarm with Ge. phototransistor and low impedance type PbS cell has been developed. The longer wavelength-limit of response is expanded to near infrared region (～2.9 microns), and it has been enabled to detect the over heated board or wall which emits near infrared radiation (～3.0 microns).
