SONOFF SNZB-09P SenseGuard Zigbee Indoor Siren – 105dB Alarm, Red Flashing Light, 10 Tones, USB-C & Backup Battery (Zigbee Hub Required)

Make every alert impossible to miss. The SONOFF SNZB-09P SenseGuard Indoor Siren is a Zigbee siren with a powerful 105dB alarm, a red flashing light ring, and 10 built-in alarm tones. Pair it with door, window, and motion sensors to build a smarter security setup for your home, shop, or garage, and know right away when something is wrong. 🚨🏠✨

You choose how loud and how urgent each alert is. Four volume levels, adjustable alarm duration, and optional flashing light let you set a high-volume sharp alarm for intrusions or a low-volume soft tone for everyday reminders. Assign different tones to different sensors, so the sound tells you where the trigger came from.

⚠️ Important Note
A Zigbee hub or gateway is required, and it is sold separately. The siren works with compatible sensors and hubs and is an add-on alert device, not a complete security system. It is for indoor use. Please keep the volume in mind for neighbors and local noise rules. ✅📡
