How Commercial Fire Sprinkler Systems Work

The fire might be genuinely disruptive for businesses and commercial buildings. A commercial fire sprinkler system is a primary part of an effective fire safety plan as it protects occupants and property in the event of a fire. These units work by extinguishing the smoke and blaze to limit the fire spreading and potential damage. Today, we`ll discuss everything you, as an owner of the commercial business, should know about these fire safety measures.

Fire sprinklers as fire prevention systems

Different fire sprinkler systems are active fire protection methods that work immediately to extinguish flames. Water is considered one of the most effective fire suppression agents for most fire types, even though it isn`t efficient for grease fires. Fire sprinkler systems and other fire safety measures, such as fire extinguishers and fire suppression systems, create an effective fire prevention structure that can save more than one life.

Commercial fire sprinkler system parts

The most common fire sprinkler system remains wet systems – the key components are water supply, sprinklers, and piping. Other commercial fire sprinkler system parts involve:

  • Water flow alarms.
  • Backflow prevention appliances.
  • Main and auxiliary drains.
  • Fire department connections.
  • Control valves.
  • System air vents.

Commercial fire sprinkler system types

When it comes to commercial fire sprinkler system types, they are classified as dry pipe, wet pipe, deluge, and pre-action. The former involves nitrogen gas or pressurized air stored in the pipes connected with a water tank. The wet pipe sprinkler systems release cold water stored in the pressurized pipes straight after recognizing the dangerous heat level. In addition, deluge systems involve activation by alarms that open the valve for water release. The last type combines wet and dry pipe systems that stand for a fast response time.

How are fire sprinklers activated?

The heated air can reach the ceiling when a fire occurs pretty fast. Once the sprinkler`s head distinguishes the hazard in high temperatures, it triggers water release to extinguish the flames. The fire sprinkler system`s operation is simple to understand – the units engage when it reveals the heated air or smoke while they work separately.

Commercial fire sprinkler system alternatives

Water is typically used in fire sprinkler systems, although it won`t suit specific environments. Individuals can consider using alternative agents in these systems instead of water in such a case. The agents, such as dry chemicals and carbon dioxide, work well to put out blazes.

Commercial fire sprinkler system inspections

The NFPA25 Standard outlines fire sprinkler system inspection requirements. According to these regulations, gauges in the deluge, pre-action, dry systems, and control valves should be inspected every week. Monthly inspections are essential for alarm valves and wet pipe gauges. Apart from that, control valves must be reviewed quarterly, while fittings, sprinkler heads, information signage, and other parts should be checked every year. The internal inspection of sprinkler piping should be conducted every five years.
