Fire sprinkler systems are one of the most reliable automatic fire suppression systems, designed to control or extinguish fires before they spread. When heat activates a sprinkler head, pressurized water flows immediately—protecting occupants and minimizing property loss.
Otis Fire Protection provides NFPA 25 compliant fire sprinkler inspection, testing, repair, and maintenance services throughout Vancouver, Surrey, Burnaby, Richmond, Delta, Coquitlam, and the entire Lower Mainland. Our ASTTBC-certified technicians ensure your sprinkler system remains functional, compliant, and ready for emergency situations.
A wet-pipe system contains pressurized water inside the piping. When a sprinkler head activates, water is discharged immediately. If additional heads activate due to spreading heat, water flows from those heads as well.
A dry system contains pressurized air instead of water. When heat activates a sprinkler head, the compressed air is released, allowing the dry valve to open and water to fill the pipes. This system is essential for environments prone to freezing. If your building has a dry system, it must be winterized before cold weather.
Pre-action systems use air or water in the pipes and require two detection events before water is released. They are used in environments where accidental water discharge may cause significant damage—such as data centers, libraries, museums, and archival facilities.
Deluge systems use open sprinkler heads. When an alarm system detects a fire, water discharges through all heads simultaneously. These systems are ideal for high-hazard environments such as power plants, aircraft hangars, and chemical storage facilities.
Otis Fire Protection provides inspection, testing, repair, and maintenance services for all sprinkler system types across Greater Vancouver.
