Power-limited fire alarm cable is used in the 3 main components of the fire alarm system



Today we focus on an important part of any business, Fire Alarm Cables and Fire Alarm systems. These were initially created to not only protect homes, but any business in the event that a fire does occur or hazard occurs that could be harmful. Fire alarm systems are very important for any business, school, facility, home, and much more. They protect us when alerts arise and deliver notification of potential threats and harm.


Power limited Fire Alarm Cables
  1. FPL which is a power-limited fire alarm riser cable is usually the least expensive because it is the most basic type of fire alarm cable and is also recognized by the NEC (National Electric Code).

  2. FPLR which is a power-limited fire alarm cables are suitable for use in a vertical run through a shaft or from floor to floor within a building. 

  3. FPLR Shielded is a power-limited fire alarm shielded cable, has the same components of the standard FPLR but, includes an aluminum polyester foil shield and drain wire to protect against outside interference.

  4. FPLP which is a power limited plenum cable and they are recognized by the NEC for use in air ducts and plenum spaces and any other space that is used for the flow of environmental air. These cables tend to be a little bit more expensive due to the additional engineering and protection they offer. All FPLP cables are listed as having adequate fire-resistant and low-smoke-producing characteristics as well. 

  5. FPLP Shielded is power limited plenum fire alarm cables with an aluminum polyester foil shield and drain wire to block an additional interference within a cable.


Fire Alarm System

A fire alarm system is a network of three main components: an initiating device, a notification device, and a control panel. The purpose of any fire detection system is to send an alert immediately to the buildings' occupants and the appropriate authorities. The quicker the response, the easier it is to solve any fire issue. 


Initiating Device:









This is the sensor that detects any indication of a fire or any other hazard for the building occupants immediately in order to take the appropriate actions. These devices include smoke and heat detectors, fire alarm sprinkler systems, manual fire alarm pull systems, etc.



Notification Device:









A notification device sounds off some type of alarm or warning sound such as a siren, horn, lights, or any other type of sensory alert to ensure any person within a facility will understand the alert that is taking place.



Control Panel:









The control panel is the intelligence of the system and it varies based on the system that is installed. There are two types of systems that a control panel will operate with, a conventional or addressable.


With a conventional fire alarm system, the panel receives a trigger signal from a detector or an initiating device. In an addressable fire alarm system, the fire alarm control panel is able to communicate with each detector individually and receives a status report so that the precise location of hazard can be identified. This allows for the issue to be handled quickly.
