Selecting the Backup Power Tactic for Emergency Lighting

Posted by Ainsley Aiken on November 22nd, 2018

Some statistics make you comprehend that how critical it is to arrange and continue proper life safety and other emergency apparatus in different types of office buildings. According to the industry experts, construction & operating codes have long been set up to look after the human life. And when it comes to UL 924, it is part of the Life Safety standards for emergency way out. It declares that apparatus shall repeatedly supply light or power or both to important areas and gears in the event of normal power cut.

In addition, Life Safety codes indicate that emergency lighting shall automatically and without delay after a major power breakdown. In applications engage with a proper utility backup, like a generator, UL 924A may meet the criteria and cut down the time of outdoor lighting inverter to thirty minutes or less.

If truth to be told, confront for building developers as well as managers is to make certain that buildings meet such needs consistently and reasonably. Here, one matter emergency lighting system designers should assess is whether to use a federal or a decentralized backup power approach in emergency lighting. The helpful answer generally is tied to the size & type of the service & related power load.

When it comes to a decentralized plan, in this, backup power is supplied to the individual machinery or set of machineries.  In an outsized facility, this is going to need a sky-scraping quantity of smaller, remote backup power machineries. Lower primary costs in this case might be balance with the ongoing keep up of so many equipments.

Apart from the above, some facilities have a preference a federal UPS approach. This lets the facility to leverage economies of scale that go together with well-built UPS units.

Bigger business facilities usually have need of a federal lighting inverter in the 10 to 200kW range, with most facilities that come under the 10 to 60kW range.  On the basis of the power requirements, a 208/277 Volt or 480 Volt output system is used. Now, let’s have a look on other aspects that are important to consider:

Verified Trustworthiness: It may be attractive to hold back on quality for a system that is not used on a regular basis, but this is precisely why trustworthiness is so imperative in an UL924 emergency lighting inverter. Even with normal testing, you may not find out that your UPS failed to endure the last thunderstorm until the time when you require it the most. For your knowledge, leveraging a well-intended & manufactured central system, with battery monitoring features can pay dividends in the components of service, control and substitution.

Besides, compatibility of power loads to backup is also an important aspect to consider when choosing battery backup plan for emergency lighting inverter.
