Feb 25, 2021   Pageview:52

Huge buildings serve a great purpose but there is one major issue with them. This is that in the case of an emergency, it gets very difficult to evacuate the building. This problem is mostly caused because of blackouts or fire or any natural disaster. In this case, it is important to keep something that could help find the way out.

Well, exit signs are the perfect example of the solution to this problem. However, most people do not know about the working of these amazing exit signs. So, here we will discuss the working and technology of these exit signs.

What is a self-powered exit sign?

Although the name says that it is a self-powered sign, it still is connected to the main electricity. This is because the exit sign must be powered using the electricity while it is available. Additionally, when the electricity is not available, the exit signs work on the battery power.

As these signs can work without using main electricity, they are often called the self-powered exit signs. However, it is worth noting that depending on the battery type and battery health, these signs only last up to 120 minutes or less.

Why are the self-powered signs needed?

As mentioned above, there are cases when there is no power in the building. In the case of gigantic buildings, it gets very difficult to move inside because of less visibility and complex routes. Additionally, if there is a natural disaster, the building must be evacuated as soon as possible to reduce the chances of any fatality or injury.

This is the main reason these signs are used. It is because these signs can last for up to 120 minutes that is enough to evacuate the building. Here the important thing is that even if the time limit of the sign can last up to 2 hours, you must try to make the building clear as soon as possible.

Benefits of having self-powered signs.

There are several benefits of having self-powered exit signs. Here we have mentioned some of the benefits of having self-powered exit signs.

  • Using the directions from these signs, anyone can exit from the building without any major issues.

  • Having these signs installed in our building means that your building meets this security standard.

  • The batteries of these exit signs can last up to 2 years which means you can spend this period tension-free.

What kind of batteries do exit signs take?

When it comes to the selection of a battery for the battery-powered exit signs, it must be able to provide power consistently for a specific period. It is because the exit signs must be bright and easily visible in the case of an emergency. This is the reason why there are only 2 types of batteries that can be used in the battery-powered exit signs. Here are the details about each of them.

Lead-acid batteries.

There are good chances that you are familiar with this name. This is the type of battery that is used in cars for ignition and provides a consistent current to power the electronics of the car. Apart from their application in a car, these batteries are also widely used in the power backup systems. Whether it is a solar power backup system or an electrical power backup system.

These batteries are used in these things because of their property of constantly supplying a consistent amount of current for the desired time. The great thing here is that now the technology of these batteries has evolved and now there is no need to keep check of the battery acid levels. This altogether makes these batteries a great choice for the battery-powered exit signs.

Nickel cadmium batteries.

These are the dry-type batteries that are used for the exit signs where size is a main constraint when selecting the batteries. These batteries can provide amazing amounts of consistent power regardless of their small size. This makes them a perfect option for using in the exit signs. These batteries are also great in extreme hot or cold conditions.

Are exit signs required to have battery backup?

While the exit signs can get power from the main electricity and still work, most people think that it is not required to have batteries in them. But this is not a good thing because the batteries are specially put in these signs to make them work even when there is no electrical power.

So, we can say that if you do not care about the battery present in the exit sign, you are making these signs useless in case there is no electricity. There are a lot of things that you need to care for when you talk about the battery-powered exit signs. Here we have mentioned some of them.

Is it important to keep check of the batteries in the exit signs?

Yes, it is very important to keep check on the battery health of the exit signs. It is because you never know when there will be an emergency and you will need these signs to work without any external power. One thing to note is that the life of these batteries is about two years.

This means that one battery can last about 2 years or even more. However, it is very important to keep check of the battery's health. For this, you can get the battery tested after every 4 or 6 months. This means that you are checking the battery twice or thrice a year meaning that you will stay up to date about the battery's health.

What batteries can you replace the exit sign batteries with?

It is very important to replace the battery-powered exit sign's batteries with only the batteries that are made specifically for them. It is because these batteries can withstand hot or cold weather and they can still provide the necessary power for a specific time.

Conclusion

A battery-powered exit sign plays a great role in the security standards of any place. So, it is very important to install them and keep check of their battery health as well. Here we discussed all that you should know about these battery-powered signs.
