Ensure the orientation of the siren allows for proper drainage if water enters the housing. Wiring the device involves connecting the positive and negative leads to your alarm control module's siren output terminals; always verify polarity before finalizing the connection. For maintenance, periodically inspect the mounting hardware to ensure it has not loosened due to engine vibration, and clean the face of the siren with a soft, dry cloth to prevent debris buildup that could muffle the sound output.
