The 513T Mini Piezo Siren (Soft Chirp) is a special-application interior siren often used as a “pain generator,” adding a sharp, piercing sound inside the cabin to make it harder for a thief to stay in the vehicle while the alarm is active. It is a compact add-on siren that pairs well with standard alarm systems when you want an extra layer of audible deterrence.
