Choose motor siren when: You need coverage beyond 500m, your site is outdoors, ambient noise is above 85 dB, or you need to meet OISD-117 perimeter coverage requirements.
Choose electronic siren when: Coverage is under 1.5 km, you need multiple distinct tones, the installation is indoors, or you're working from a 24V DC control panel output.
