Several low-voltage switches shall be set in the fire pump room.

According to the Atlas of Building Water Supply, Drainage and Heating Engineering (GB 500 15-2003), the fire pump room needs at least two low-voltage switches. These two low-voltage switches correspond to two pumps respectively, which can monitor and control the working conditions of the two pumps respectively. In practical engineering, a standby low-voltage switch is sometimes added as needed for patrol inspection, maintenance and switching. Specifically, several low-voltage switches should be set, which should be determined according to the actual situation and design requirements.
