Question: Can a fire alarm system be shared with an instrument UPS? Which specification requires it?
A fire alarm system should generally not share a UPS with other devices, as it needs to have an independent and reliable power supply in emergency situations. Relevant codes can refer to the Code for Design of Fire Protection Facilities in Buildings. .
No, the fire alarm system should be installed separately.
Thank you for the reply. Could you provide the standard number?
50770 specifies that an uninterruptible power supply (UPS) should be used for power supply; it is advisable to adopt a dual-UPS system, with the two power supply circuits being independent of each other. There is no requirement that different systems need separate UPS units; they can simply be powered by separate circuit breakers connected to the UPS. In other words, the UPS can be shared
