Kidde Intelligent Addressable Dual Optical / Heat Detector with Sounder & VAD (KE-DP3121W-SNV)

The Kidde KE-DP3121W-SNV is an intelligent addressable dual optical/heat multisensor detector with a built-in sounder, visual alarm device (VAD) and loop short-circuit isolator, from the Kidde Excellence Series, finished in white. It detects fire and gives audible and visual warning from one ceiling device, fitting the Excellence Series standard base. It is designed for Kidde Commercial Excellence fire systems and is certified to EN 54-3, EN 54-5, EN 54-7, EN 54-17 and EN 54-23.
