The SD505-AHS is a heat detector suited to virtually any commercial setting. The
SD505-AHS is an absolute temperature device. This means that it responds to an
alarm immediately if the temperature goes above the trip point (programmed at
the panel). The SD505-AHS 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.
