The Yale AL-IS-1A-V1 Indoor Siren is a wireless alarm unit designed for use with a smart home security system. Compatible with Android devices, this siren emits a loud noise to alert you of potential security breaches. The package includes the alarm unit itself, making it a convenient addition to your existing home security setup. With the trusted Yale brand and reliable connectivity, this indoor siren provides peace of mind for your home or business. I bought this for a HSA Alarm system but it is not compatible. Please check that is compatible with your Yale Smart Alarm before purchase.
