The existing fire extinguishing system design is not equipped with a backup pump and a jockey pump. Based on The DKI Jakarta Governor Regulation No. 92/2014 and the Indonesian National Standard, to solve this problem, a building fire pump system is designed with a combination of the jockey pump, main pump and backup pump that connected in an integrated parallel arrangement. This design allows the backup pump to automatically run due to a pressure drop in the system pipe if the main pump fails or unable to build up pressure. When a fire occurs and a lot of hydrants are used, the backup pump will automatically run to help the main pump with a signal triggered by the pressure switch. 1. INTRODUCTION Multi-storey building must be equipped with a fire extinguishing system. The building fire system must comply with applicable standards. The DKI Jakarta Governor Regulation No. 92/2014 is one of the standards related to the building fire pump system applicable in the DKI Jakarta area. Based on fire extinguishing standards, the main part of a building fire extinguisher is the pumping system in the pump room consisting of the main pump, backup pump, and runway pump. The current fire extinguishing pump system design discussed in several previous journals has a weakness in the absence of a backup pump or it is equipped with a backup pump but is not integrated with the main pump. There is a risk of danger if the main pump fails to operate in a fire emergency. This paper discusses the solution of the existing problems by designing a building fire system using a main pump and a backup pump that are connected in parallel with an integrated running scenario in accordance with the DKI Jakarta Governor Regulation No. 92/2014 concerning Technical Requirements and Procedures for Installation of Pipe and Fire Hose Systems and Yard
