Universal Mini Backup Battery Siren

The MINISBB is a streamlined backup siren designed to fit GTR and RSA car alarm systems. In the event of main system tampering or battery failure, this siren activates via a coded trigger and continues sounding with its own battery power - helping ensure your alarm stays audible when it matters most. Despite its powerful function, it's compact and discreet, easily installed in tight vehicle spaces.

• Compact Size: 55 x 65 x 75mm, making it easy to hide during installation without affecting cabin space 
• Heavy-Duty Build designed for long-term durability and reliable performance in vehicles
