Flow Switch

The Sensor of Hydraulic Action: Pinpointing Fire Emergencies with Premium Flow Switches

In modern multi-story infrastructure and commercial facilities, automatic fire suppression must be backed by immediate localized intelligence. While sprinkler heads work independently to contain flames, building safety teams require instant notification of where the suppression is occurring. Our Premium Water Flow Detector Switches bridge this gap, translating mechanical water movement into crucial electronic alerts that slash emergency response times.

Installed downstream of zone control valves, the flow switch utilizes a custom-molded polyethylene paddle nested inside the main water path. The moment a sprinkler opens and water velocity exceeds 10 GPM (Gallons Per Minute), the paddle deflects smoothly, activating internal electrical contacts to pin down the active fire zone on the central control panel.

Rugged Industrial Sealing Engineered for Total Reliability

Operating inside demanding plumbing shafts, utility enclosures, and mechanical risers, our water flow switches are constructed to withstand harsh real-world conditions. Featuring a heavy-duty, weather-resistant die-cast metal enclosure, the internal switches are fully gasketed against high humidity and water splashing. Backed by its mechanical retard assembly, the device delivers absolute signal integrity by filtering out non-emergency hydraulic surges.

Key Performance Features & Specifications:

• Instant Zone Identification: Delivers immediate, high-precision electronic signals to locate active fire suppression loops instantly.

• Adjustable Pneumatic Retard Mechanism: Built-in timer delay (0 to 90 seconds) designed to eliminate disruptive false alarms caused by supply line surges.

• High-Endurance Durable Paddle: Specially shaped flexible paddle that handles high-velocity water movement without breaking or causing friction loss.

• Dual SPDT Output Contacts: Equipped with two sets of internal switches, allowing simultaneous wiring to the master fire panel and local alarm bells.

• Elite Fire Code Certifications: Meticulously engineered to maintain top global compliance badges, holding official UL Listing and FM Approval marks in strict accordance with NFPA 13 and local Civil Defense criteria.
