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.

- No USB-C power supply is supplied with the unit.
- Anything wired into mains power should be fitted by a qualified electrician.
