Flush Mount combo piezo / internal siren. Low-profile flush mount internal alarm screamer designed to deliver a powerful high-frequency warning tone when an alarm system is triggered. Ideal for discreet indoor installations where strong audible deterrence is required. The Flush Mount Piezo Screamer WP05 is a compact internal alarm sounder designed to mount neatly into ceilings or wall cavities, providing a clean and unobtrusive installation. Despite its small size, the unit produces an intense high-frequency tone engineered to be uncomfortable to remain around, helping drive intruders away quickly.
