SKU: 515R
$35.00
The Directed 515R Backup Battery Siren is an optional accessory designed to boost your car’s alarm system protection by continuing to sound even if the vehicle’s main battery is disconnected. Installed alongside your existing Avital (or compatible Directed/Viper) alarm system, this siren provides uninterrupted audible alert during tampering or theft attempts.
A1: It’s a backup battery siren that works with Avital and Directed alarm systems to keep the siren sounding even if the main car battery is cut off.
A2: In the event thieves disconnect the main vehicle battery to silence the alarm, the 515R’s built‑in battery allows the siren to continue sounding — enhancing theft deterrence.
A3: Rechargeable internal battery, professional installation support, and compatibility with many Avital/Viper/Directed alarm systems.
A4: No — the 515R is a siren accessory, not a complete alarm system and does not include remotes.
A5: Yes — it typically requires professional installation integrated into your alarm setup.
