The DZ-1020B Crossing Bell Sound Module is designed to work with the DZ-1020HO-S and DZ-1020N-S Crossing Signals from Z-Stuff. The authentic crossing bell sound is generated when the YELLOW input wire of the DZ-1020B is connected to common (0V.) by the output of a DZ-1020HO/N, an isolated rail contact, push button, or other signal. The sound module is mounted inside the speaker housing, so the DZ-1020B only requires power (AC or +DC) connected to the RED wire and common (AC or -DC) to the BLACK wire.
