Incorporated in 1997, Spectrum Fire Protection started out with only four office staff and four field employees. SFP has grown to hearly 50 full time employees ranging from inspectors to alarm technician and sprinkler fitters.

We are licensed in Maryland, Pennsylvania, Virginia, and West Virginia. We are members of NFPA (National Fire Protection Association), AFSA (American Fire Sprinker Association), and with NICET (National Institute of Certified Engineering Technicians) engineers on staff. SFP handles residential, industrial, commercial, aircraft buildings and design build fire protection projects.

Our engineering staff is NICET certified which is required in most of the tri-state area. Our estimating department is well trained in providing the best economical fire sprinkler/fire alarm packages to best suite the owner needs. Our installation department is AFSA trained and certified. Our service department is staffed three hundred sixty five days a year, twenty four hours a day in the event of an emergency.



Fire Sprinkler Systems

Our sprinkler systems are designed for each particular facility and are built to meet or exceed fire codes and insurance requirements. Our team of engineers and technicians can furnish, install, inspect, repair, and service the following equipment:

  • Wet Fire Sprinkler Systems
  • Dry Pipe Systems
  • Pre-Action Systems
  • Deluge Systems
  • Standpipe Systems
  • Fire Pumps

Each system has a unique and special use. To learn more about the systems you may have installed within your building, please feel free to email us or call at 301-223-0000.

Wet pipe sprinkler systems

are the most common systems. A wet pipe sprinkler system is under pressure, fully fitted with water at all times. These systems are installed in heated spaces where temperatures are maintained above 42 degrees.

Dry pipe systems

are usually installed in parking garages, outside loading docks or other similar cold conditions. A dry system is filled with air instead of water to protect the system from freezing. Most types of dry pipe vlaves require a suitable level of priming water. The priming water (usually about a gallon of water) is used in combination with the air pressure above the priming water to hold the tripping mechanism in place. When a sprinkler head is fused, the air will be released. When the air is at a point where the tripping mechanism could no longer stay closed, the system will trip causing the system to fill with water.

Pre-action systems

are usually installed in computer rooms or other types of conditions where accidental water damage needs to be avoided. It's like a dry system although the system is tripped much differently. A pre-action system does not rely on air pressure to trip the valve. The air pressure is used as a supervisory alarm to let people know there is a problem with the system. A pre-action system is tripped manually or electrically using a solenoid valve. A pre-action system requires a separate activation panel to electrically trip the system. In most cases smoke detectors or rate of rise heat detectors are to trip the valve. When a smoke detector or rate of rise heat detector is activated (within two separate zones usually), the pre-action system will trigger the solenoid valve tripping the valve flooding the system. At this time the system is kind of like a wet system. No water will be present until a sprinkler head is fused.

Deluge types of sprinkler systems

are very interesting. The sprinkler heads or nozzle type sprinkler heads are open at all times. Deluge systems are usually installed in conditions where water is required over the entire protected area. Deluge systems are electrically or manually tripped like the pre-action system. In some cases could be designed to reset automatically. Deluge systems have also been used in power plants to cool down electrical transformers.

Standpipe Systems

are plumbing networks which allow large volumes of water to be brought to any floor of a building to supply firefighters' hose lines. The pipes for this can be observed inside the stairwells of the building. The standpipe extends from the lowest level of the building to the roof, with outlets at each level. If a fire occurs, the fire department will connect hose at the safest point closest to the fire.

Fire Pumps

are part of a fire sprinkler system's water supply. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes.
