The Interlogix MPI-47 "screamer" is a complete and advanced piezo device. Patented technology provides a powerful sound output with a minimum of current consumption. This makes the piezo "screamer" suitable for use with many of today's control panels, even those that provide only limited power for audible devices.
Unlike a conventional speaker, a piezo is a crystal type resonator, which provides a broad sound dispersion and a longer service life. Piezos emit a piercing high frequency sound, which is very intense close-up -- ideal for smaller houses or stores, apartments or pre-alarm applications.
