Silent Knight's SD505-HEAT is an analog addressable heat detector head from the IntelliKnight detector family. It is an absolute-temperature device, meaning it alarms when the temperature rises above a trip point programmed at the control panel. It suits kitchens and other areas where steam or cooking fumes rule out smoke detection. This listing is for the detector head only.
