FIELD: engineering of optical-electronic devices, possible use as indicator device for provision of information safety of service rooms, offices, etc. ^ SUBSTANCE: device containing observation pipe including body, objective and ocular, emitting channel containing a source of visible radiation, lens, reflective prism glued to internal surface of objective. Reflective side of prism is mounted on optical axes of lens and objective at and angle thereto. Device also includes a cover made of upper and lower parts and having cross-section shape close to oval, first and second rings. Circular shelves are made on end surfaces of cover. In upper part of cover three recesses positioned serially are made and an aperture, and in lower part power block unit is positioned made in form of solid cylindrical aperture on frontal end surface and recess close to back end surface of cover. First and second rings are mounted on circular shelves of, respectively, frontal and back end surfaces of cover. Switch is mounted in aperture on upper part of body. ^ EFFECT: simplified construction, increased comfort of operation. ^ 2 cl, 3 dwg |
