Hooter Cum Strobe FDS183C-EN

The audible and visual fire alarm FDS183C-EN can send audible and visual alarm signals when connected with a DC 24 V power supply. It can be used with bus fire alarm controller via I/O module, and also can be combined with gas fire alarm to create a gas fire alarm system. When an accident occurs, the I/O module receives the start signal from the controller and drives the audible and visual alarm to send dazzling flashing signals and harsh audible alarm signals that alert the field personnel to quickly understand the occurrence of a fire on site and take measures for evacuation as soon as possible, thus avoiding major accidents. FDS183C-EN is designed for audible and visual alarm at the scene of accident, and can be used in public space, hotels, entertainment venues, factories, shopping malls, hospitals, schools, office buildings, stock exchanges and other places, especially the locations with low visibility or smoke production.
