ix Different Categories Of Fire Alarm Cable


You must know that fire alarm systems in Glendora and elsewhere are extremely crucial for any educational institution, hotel, hospital, business, facility, home, and much more. We expect that they will protect us whenever alerts arise. Then they are supposed to deliver notification of potential threats, damages, and harm.  

If you are supposed to handle the fire alarm of a particular building, then you must know the way fire detection systems work and the differences between conventional and addressable fire alarm systems. 

In this article, we will describe the various categories of fire alarm cables with both power-limited and non-power-limited fire alarm cables. So, let's get started.  


Power Limited Fire Alarm Cables 


  2. 1. FPL  


FPL happens to be a power-limited fire alarm riser cable. It is generally the least expensive as it is the most fundamental category of fire alarm cable and is approved by the National Electric Code or NEC as well. FPLR cables are ideal for being applied in a vertical run through a shaft or from floor to floor within a premise.  


  2. 2. FPLP  


FPLP is a power-limited plenum cable. They are also being recognized by the NEC. However, they are for use in air ducts and plenum spaces, and any other space that is utilized for the flow of environmental air. These cables tend to be a little bit more costly because of the extra engineering and protection they provide. All FPLP cables are listed as having sufficient fire-resistant and low-smoke-producing characteristics too. 


  2. 3. FPLP Shielded  


FPLP Shielded cables happen to be the power-limited plenum fire alarm cables featuring an aluminum polyester foil shield and drain wire to resist extra interference within a cable. 


  2. 4. FPLR Shielded 


FPLP Shielded, as the name suggests is a power-limited fire alarm shielded cable. It has similar components to the standard FPLR. However, it comprises an aluminum polyester foil shield and drain wire for protection against external interference. 


Non-Power Limited Fire Alarm Cables 


  2. 1. NPLF 


Non-power limited fire alarm cables or NPLF cables are recognized by the NEC. They are suitable for all regular uses of fire alarm cables. But they cannot be used in ducts, risers, or plenum spaces that are used for environmental airflow unless they are correctly installed within a conduit. 


  2. 2. NPP 


Non-power limited fire alarm cables or NPLFP cables are recognized by the NEC as well. However, these cables are ideal for installation in plenums, ducts, and other spaces where environmental air flows.  


Conclusion 


So, these six fire alarm cables were the six different types that are available at present. If you can hire the provider of the best fire alarm service in Glendora, then they will update you about each one of them and which one will be suitable for your home or workplace.

For that purpose detailed testing by manipulating the load over specific periods of time is needed to understand the behavior of the same under production use or excessive pressure. Soak test is done by the professional and reputed  fire alarm monitoring companies in California  for that purpose.  Soak test on a fire alarm system: The professional service providers soak tests the fire alarms to ensure their activeness at any point in time. They are trained and experts in this field and they test the smoke alarms by using a small amount of radioactive material between two electrically charged plates that ionize the air and cause electricity to flow between the plates. Then they send some smoke in the chamber to see if it is reducing the flow of current by disrupting the flow of ions, which activates the fire alarm. The expert technicians at the p
