Police, ambulance, and fire engines, such as emergency vehicles, emit sirens, announcements, and warning lights controlled by the e-SRN Siren-Anons device, are an innovative siren system that can be used both wired and wirelessly. It is based on the idea of integrating multiple functions into a single device. The control panel's keypad allows for the broadcast of announcements, as well as the sound and light control of alerts. A sunlight-readable color TFT screen simulates the system's flashing mode, and errors on the beacon are visually displayed. A command menu, which displays status information such as the siren type, day/night mode, and volume level, allows for the configuration of numerous functions and the selection of specific features. Siren sounds can also be downloaded to the device via a separate configuration program, and the device can broadcast siren frequencies for the country or sector in which it will operate. The e-SRN siren model's screen visually simulates multiple operating functions, and the user is informed of errors, indicating the type and location of the error. Wired and wireless operation and multifunctionality: in addition to wired operation, when the remote control cable is removed, the remote control automatically switches to wireless mode and can perform all system functions wirelessly without any loss of functionality.
