FIELD: radio engineering, communication.SUBSTANCE: device comprises a housing, an emergency signal transmitting device (UPAS) system board with a terminal block, an integrated power supply unit, a TARB plus board, a speaker and a microphone. The UPAS system board is mounted on the inner side on the base of the UPAS housing, said system board being configured for connection to the electrical power line of a passenger carriage via the terminal block, the integrated power supply unit and the TARB plus board, the outputs of which are connected to the speaker and the microphone, mounted inside on the cover of the UPAS housing. The TARB plus board has a socket for connecting a DECT antenna. The integrated power supply unit and the TARB plus board are connected to the UPAS system board. The cover of the UPAS housing has means of guiding the outputs of signalling lines installed in passenger carriages to the terminal block of the UPAS system board. The UPAS housing has a socket for connecting an electronic registration key reader. The base of the UPAS housing is fitted with means of inputting cables from carriage signalling systems, as well as from the power supply system of the apparatus.EFFECT: high reliability of the apparatus.2 cl |
