The Choice Between NPLFA and PLFA Fire Alarm Circuits

The Choice Between NPLFA and PLFA Fire Alarm Circuits

All the great fire alarm technology has allowed most people to protect their homes with at least some kind of system. The simplest, most inexpensive, systems are nothing but small, plastic boxes which hang on a wall or ceiling. It is capable of sensing smoke and then sounding an alarm to warn the building’s occupants.

Fire alarm systems are responsible for saving millions of lives. However, they fail in around thirty percent of all fires allowing more tragic deaths to occur than should be. Sad but true, fire alarms can also cost lives when people rely on them and they don’t perform as expected.

Different Alarms Operate on the Same Basic Concepts

You will find hundreds of different fire alarm systems on the market. These run all the way from basic, do-it-yourself alarms to fancy and complex home fire alarm systems. No matter what you choose, you will need to connect it via either NPLFA or PLFA circuits. The difference in these circuits is that instead of remaining on all the time or needing to be operated manually, the circuits remain broken unless a fire alarm sounds.

The newest fire alarm circuits are extremely sensitive. They work so well that it’s almost like they can “see” the smoke. In the case of a fire that creates a lot of smoke, such as a smolder, they perform especially well. There are units available that can respond to extreme temperature changes that happen within a very short time. If the sensor detects a big change in temperature, a fire alarm circuit breaks causing the alarm to sound.

A Notification Appliance Circuit expansion is a necessary option on the model you buy. This will provide back-up power to the miscellaneous accessories that are part of the system. You can find reliable systems that meet your price range, your own preferences, and the requirements of your specific site. Basic units are available for around $50, while more intricate designs will cost you as much as $300. Built by renowned fire equipment companies, such as Altronix, Fire-Lite, and Kidde, you’ll know you can trust the circuits you buy.

The NPLFA fire alarm circuit can work at up to 600 volts with unlimited power. The PLFA, on the other hand, has its power limited by a listed power source. Although the two systems are basically alike, the PLFA is easier to install. Both types of units will include over current protection, wiring methods, conductor size and insulation, and the number of conducts in a raceway.

Do some extra online research into both the NPLFA and the PLFA before choosing which you feel’s the right choice for you. You know you’ll make the best choice possible, because the safety of your family could be riding on it.
