48BFC000 is an optical beam detector which provides protection over distances ranging from 3 m to 30 m and up to 15 m wide. Equipped with an integral laser and a set of passive reflectors, it is ideal for use in areas where the installation of standard point smoke detectors would be too problematic or impossible. The integral laser allows simple auto-alignment without the need for any special instruments or equipment. Also equipped with two changeover relay contacts for alarm and fault signalling.
