Overview

The SONOFF SenseGuard Indoor Siren, model SNZB-09P, is a small sound-and-light alarm for homes, shops and garages. Once a paired sensor is triggered, it can sound, flash red, or do both, and it can also send an alert to your phone.

A lithium cell inside the unit keeps the alarm working through a mains failure, so a leak or break-in is still noticed.

Before you install

  • Zigbee connectivity depends on a hub or coordinator, since the siren has no Wi-Fi and cannot connect to the network alone.
  • No USB-C power supply is supplied with the unit.
  • Anything wired into mains power should be fitted by a qualified electrician.
