Flush Mount combo piezo / internal siren

Model / SKU: WP05

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. This type of screamer is commonly installed inside residential and commercial alarm systems as an internal siren, reinforcing the external siren by creating a loud acoustic environment indoors. Its low current draw allows easy integration with most security alarm control panels while maintaining reliable performance during alarm activation.
