In hotels, hospitals, high-rise residential buildings, large commercial complexes and other places with high occupancy, it is mandated to install smoke ventilation systems. According to relevant statistics, thick smoke is the primary cause of casualties in building fires. The core function of a smoke ventilation system is to rapidly exhaust toxic smoke during the early stages of a fire, gaining more crucial time for people to escape. At the same time, we will install UPS for smoke ventilation system to ensure it can maintain normal operation with sufficient power support even during a mains power outage, which will help trapped individuals gain more time to escape.
Why do I need a UPS for the smoke ventilation system?
Once a fire breaks out in a building, it is highly possible that electrical power will be cut off. In such cases, smoke ventilation systems, which rely on electricity, will be unable to draw out thick smoke. As a result, trapped people will be exposed to higher levels of toxic fumes. And smoke ventilation UPS is an uninterruptible power supply specifically designed for smoke ventilation systems. It can ensure that the smoke exhaust system receive sufficient power support at critical moments.
We recommend using a dedicated lithium UPS for smoke ventilation systems because smoke exhaust fans are motor-type loads which generate currents as high as 5 to 7 times the rated current at startup. If you install our standard tower type lithium UPS typically used for computers, the system is likely to trigger overload protection and shut down when the smoke exhaust system starts up.

What is the function of UPS for the smoke ventilation system?
Ensure the smoke exhaust fan has sufficient power supply when needed
Smoke exhaust fans are the core components of a smoke ventilation system, able to extract toxic smoke from the building. When fire occurs, electrical cables may be damaged by fire, and fire departments may proactively cut off non-fire-related power sources. Without a backup power source, smoke ventilation system will cease operation upon loss of mains power, which could lead to smoke rapidly filling the entire passageway. With the smoke ventilation UPS, it can seamlessly switch to battery power within milliseconds when mains power is interrupted, ensuring the smoke exhaust fans keep running and do not experience any power interruption.
Protect the components of the smoke ventilation system
A smoke ventilation system consists of electronic components such as controllers, smoke detectors, motorized dampers and variable frequency drives. These components are highly sensitive to power interruptions. In other words, mains power outages can damage these components. Furthermore, power fluctuations and harmonic interference in the mains supply can cause the equipment to malfunction or freeze. But Virtue UPS for smoke ventilation systems is an online UPS that switches to battery power mode when mains power fails. It also cleans up impurities in the mains power supply to provide a clean and stable power output.
Provide sufficient time for the generator to start
Shopping malls, large office buildings and other structures are typically equipped with diesel generators as backup power sources. However, the generator requires 10 to 30 seconds to start up and begin delivering a stable power output. During this time, smoke ventilation UPS can supply power, ensuring the smoke exhaust system continues to operate without interruption until the generator takes over.
Smoke ventilation UPS and generator, which is better for a smoke ventilation system?
When comparing smoke ventilation UPS system and generator, smoke ventilation UPS primarily addresses short-term power supply needs, while generator is designed for sustained power output over extended periods. Generally, lithium UPS can provide 15 to 60 minute backup time. Of course, we can manufacture lithium UPS tailored to your specific time requirements. On the other hand, generator can supply power for several hours or even days once started.
In fact, generator and UPS for the smoke ventilation system are the ideal combination. Because during the transition from power outage to stable power supply from the generator, UPS can provide power to ensure the smoke ventilation system does not stop operating. Furthermore, it is explicitly stipulated in fire safety regulations worldwide that smoke ventilation systems and other critical fire safety equipment must be powered by two independent power sources. And smoke exhaust control components that rely on volatile memory must be equipped with a UPS capable of providing at least 15 minutes of backup power. Therefore, both the UPS and the engine must be properly installed.
How to choose UPS for smoke ventilation system？
It is essential to select a UPS with a short switchover time. If the transition from mains power to battery power takes too long, the smoke ventilation system will detect the power interruption and shut down. This not only damages internal electronic components but also reduces the efficiency of smoke extraction. And you need to confirm the UPS power capacity and backup time. The UPS power capacity should be 2-3 times the rated power of the exhaust fan. It can avoid the starting current of the smoke exhaust fan triggering system shutdown. And according to mandatory fire safety regulations, the backup time must be at least 15 minutes.
Moreover, the quickest way is to consult a reliable smoke ventilation UPS manufacturer to obtain a tailored solution. As a lithium UPS solutions supplier with extensive experience , we can provide the optimal uninterruptible power supply solution based on the actual conditions and requirements of your smoke ventilation system. Additionally, we can offer alternative solutions based on LiFePO4 batteries for your lead-acid UPS.
Conclusion
UPS for smoke ventilation system is critical to life safety. Therefore, we must carefully verify UPS type, battery runtime, power capacity and other details to ensure the smoke ventilation system operates properly when needed, thereby providing trapped individuals with more valuable time to escape.
