When Can UPS Systems be Used to Backup Fire Suppression Systems?

At SIEL Energy Systems we understand that fire suppression UPS systems must not only comply with the British safety standards but they must also comply with the product safety regulation EN 62040.

Fire suppression systems are not a legal requirement in the United Kingdom. However many businesses choose to install them to reap a long list of benefits. One is the extended runtime of 180 minutes which allows care homes to benefit from having the vital extra time to evacuate, retail premises benefit from being granted longer distances to travel to emergency exits and landlords have the freedom of providing open plan dwellings.

Fire suppression systems are interlinked with a central power supply to automatically activate in the event of a blaze which is why a method of backup power, such as a UPS system, must be present to comply with BS EN 50171. Where a UPS system is used it must also comply with product-specific regulations highlighted in EN 62040 and its relevant parts.

SIEL is an exclusive UK representative for Borri Spa, meaning we can provide turnkey solutions for life safety systems such as fire suppression. Our product range offers sizes from 10 – 50 kVA (3/1)– 3/3) in the Borri E8000 range of UPS units, and from 50 – 160kVA (3/3) with the Borri Ingenio ECS, all Borri Emergency Central Systems (ECS) units have been exclusively designed to meet both the product standard IEC/EN 62040 and the European Compliance standard EN50171. This means they can be used as a CPSS (Central Power Supply System) rather than a distributed power supply, therefore removing the need for complex electrical design and considerably reducing the overall maintenance costs.

Due to the many factors that should be taken into account when sizing a life safety system, One being the high inrush currents required to start a pump, there are many risks to be avoided in providing UPS solutions to support fire suppression systems. Other UPS providers will either fail to take these start-up currents into consideration leading to an unreliable solution or an oversized UPS unit.

SIEL specialise in all aspects of power quality and reliability, we can provide a VSD (variable speed drive) alongside the ECS UPS. This means the start-up current is limited to 1x the running load preventing the need to oversize the UPS.

Incorporating this technology with Borri’s excellence in manufacturing, SIEL Energy System are able to offer the full package every time.
