FireX - Smoke Alarm - Model FADC #5000


The FireX Model FADC item #5000 does not have a stand-alone horn with a piezoelectric disc inside the horn. The grill opening on the faceplate is the horn opening. On the backside of the grill opening, there is a cylinder that acts as the horn cavity. Pressed against the open end of the cylinder is the metal side of a Piezoelectric disc. The electrical connections to the etched side of the piezoelectric disc are via spring metallic pins on the printed circuit board. See the photos below.

The Model FADC #5000 was introduced in 1999 and was still being manufactured in September of 2006 (perhaps later). Kiddie purchased FireX from Invensys Controls in 2007; Invensys Controls purchased FireX from the Maple Chase Company in late 1999 or 2000.
