The IQ Siren allows you to increase the volume of your siren even louder when the alarm goes off. At 105 dB, an auxiliary siren makes sure that your security breach gets noticed. Placing it near a front door where most intruders enter ensures that they hear it. It is completely wireless, and it plugs into any standard outlet. There are 3 LED lights that strobe when the alarm triggers.
In addition, the siren acts as a Z-Wave repeater to strengthen and improve your smart home network, increasing the performance of all your smart home devices. Install up to three IQ Sirens with your IQ Panel. It runs on the power from the outlet it plugs into. But, in the case of a power outage, it has a built-in rechargeable, 3-hour battery backup.
