The SD505-HEAT is a heat detector suited to virtually any commercial setting. The SD505-HEAT is an absolute temperature device. This means that it responds in alarm if the temperature goes above the trip point (programmed at the panel).
The SD505-HEAT provides accurate temperature measurement data to the fire alarm control panel. This heat detector is particularly suited to environments where smoke detectors cannot be used because of the presence of steam or cooking fumes, such as in a kitchen.
