Waco Pre Action Standpipe Sprinkler Systems

Pre action standpipe fire sprinklers are installed where an accidental flow of water from fire hose connections, fire department connections, fault valves or sprinkler heads would destroy property, appliances or inventory. Pre action sprinklers are generally void and remain dry of fire extinguishing agents such as water, foam concentrates, chemicals or gases such as carbon dioxide (CO2) until the detectors and sensors are triggered from heat, a fire condition or explosion. This system is combines the ease of wet standpipe fire sprinklers reaction times to fire events with the beauty of a dry standpipe system void of water until times of emergency.

Pre action standpipe fire sprinklers are installed in areas where accidental water discharge could potentially damage data centers, computers, museum or art galleries, files, computers, laboratories, or other sensitive appliances or materials or in colder climates where lines may freeze. Accidental discharge of water could be from broken sprinkler heads that are faulty and do not open or frozen, ruptured or broken sprinkler lines. Pre action systems are very complex and should be installed, maintained, serviced, tested and inspected by experienced fire sprinkler companies in Waco.

Single Interlock Preaction System

Similar to a dry standpipe fire sprinkler system a single interlock pre action system keeps all lines and sprinkler heads void of fire extinguishing agents such as water, foam, chemical or gas like carbon dioxide (CO2) until the detectors and sensors trigger an event due to fire conditions present. Pre action single interlock systems use special pressure regulating valves that keep lines empty, once an event triggers the single interlock pre action system fills with extinguishing agent which disperses from sprinkler heads.

The advantage to installing a single interlock pre action system over dry standpipe is the reaction time of sprinklers to respond to fire can be faster. Reaction to a fire can greatly assist in extinguishing, suppressing or containing the rapid spread of fire. Single interlock pre action sprinkler systems are complex and should be installed, serviced, repaired and maintained by experienced actively licensed fire sprinkler companies in Waco.

Double Interlock Preaction System

Double interlock pre action system keeps all lines and sprinkler heads void of liquids until the event of actual fire or explosion. The double interlock pre action system features additional fail safe actuators, sensors and detectors that also must be triggered for the system to release fire extinguishing agents such as water, foam, chemical or gas like carbon dioxide (CO2).

Double interlock pre action systems have reduced failure rates from malfunctions or damage to sprinkler heads or piping from broken lines, heads or valves. Reaction times can be impaired with these systems depending on the manufacturer, valves, heads, devices and components used. Double interlock pre action standpipe sprinkler systems are complex and should be installed, serviced, repaired and maintained by experienced actively licensed fire sprinkler companies in Waco.

Waco Preaction Fire Protection | Installations

Hydraulic calculations are initially done to ensure adequate water supply, backflow preventers are installed to stop back flow of water into freshwater systems. Every design detail of the installation down to where each fire hose connection, fire department connection, fire sprinkler heads are located, how many alarm valves, sprinkler alarm switches, sprinkler heads, pipe hangers, supports and valves is crucial to the preaction standpipe fire sprinkler engineering, function & operation.

You'll want an experienced fire sprinkler company, possibly a fire protection engineer (FPE) to design, engineer and install an preaction fire sprinkler system as they are very complex systems for ordinary contractor or subcontractors and for bond and insurance purposes. In Waco fire sprinkler companies that are confident with preaction standpipe fire sprinklers will offer their estimates, bids or quotes to service, maintain, test, inspect or install the systems.
