Z-Wave sirens are an integral part of your home automation and security system, notifying your Z-Wave controller whenever an unexpected event like intrusion, smoke, water break, etc. is detected.
Depending upon your environment, you can either choose sirens like Z-Wave Aeon Labs Siren that trigger a cut and the loud 106db alarm, or pick more advanced sirens like Z-Wave The Fortrezz Siren & Strobe Alarm that come with a strobe light and provide tamper and low-battery notifications.
