Wet Pipe Sprinkler Systems
Wet pipe sprinkler systems are the most widely used. They operate with water stored directly in the pipes, often supplied by the city water supply, ready to discharge immediately when a sprinkler head activates. They are ideal for buildings with consistent indoor temperatures, such as offices, retail spaces, and facilities with storage racks that require in-rack sprinklers for added protection.
Dry Pipe Sprinkler Systems
Dry pipe systems are designed for environments where freezing is a concern. Instead of water, the pipes are filled with pressurized air or nitrogen that releases water only when a sprinkler head activates. These systems are a smart choice for unheated warehouses, parking garages, and outdoor storage areas. They require slightly more maintenance due to their complexity but provide excellent protection in freezing conditions.
Pre-Action Fire Sprinkler Systems
Pre-action systems combine the benefits of wet and dry systems, requiring a two-step activation process. Ideal for environments where accidental discharge would be costly, such as data centers or museums, these systems only release water when both the fire detection system and sprinkler heads are triggered. Their added layer of protection makes them a preferred choice for sensitive facilities.
Foam Sprinkler Systems
Foam sprinkler systems are designed for spaces with flammable liquid risks, like chemical plants and industrial facilities. These systems combine water and foam concentrate to quickly smother fires and stop re-ignition. Allied customizes foam sprinkler systems to fit your specific hazards and comply with national fire codes.
Fire Pumps
Fire pumps provide the water pressure needed to keep your fire sprinkler system running smoothly, especially in larger buildings or areas with low municipal water pressure. At Allied, we design, install, and maintain fire pump systems, giving you peace of mind that your system will perform when it’s needed most.
Backflow Preventers
Backflow preventers keep water flowing in one direction, protecting your water supply from contamination. These essential components are required for fire sprinkler systems to meet health and safety regulations. Allied’s experienced team provides expert installation and maintenance to keep your system compliant and running smoothly.
Fire Water Tanks
Fire water tanks, also known as fire suppression tanks, provide a dedicated water supply for your fire sprinkler system. They’re especially valuable in remote locations, during municipal water outages, or when additional water is required. Allied evaluates your building’s specific requirements to recommend and deliver the right fire water tank for dependable protection.
Underground Fireline
The underground fireline is the backbone of your fire sprinkler system, connecting it to the municipal water supply. Count on Allied to manage every detail, from excavation to installation and testing. We make sure your underground piping meets local codes and delivers reliable water to your fire protection systems.
