Courtesy: SiemensThe 520-Hz, Low-Frequency Sounders have been established to comply with the latest requirements for low frequency for sleeping rooms, per NFPA. It has multiple 520-Hz modes of operation, low-current draw, wall-only mounting, and a finger-slide switch for field-configurable settings. Both low-frequency sounders feature the following 520-Hz modes for operation: Temporal Code 3 (FIRE), Temporal Code 4 (Carbon Monoxide [CO]), Continuous Horn, or DSC Control (T3/T4). The horns are specific to indoor, wall-mount installations and are powered by 24 Vdc sound output. They are also Restriction of Hazardous Substances (RoHS)-compliant.
