The Haws 5726850 is an electromagnetic flow switch specifically designed for integration with emergency safety equipment alarm systems, such as the Haws 9001.5 alarm. It provides reliable flow detection for eyewash stations, safety showers, and other emergency fixtures, triggering an alarm when water flow is detected.

How It Works

When water flows through the switch at or above the activation threshold, the internal mechanism triggers the DPDT (Double Pole Double Throw) contacts, which can be wired to activate an audible or visual alarm, such as a buzzer, flashing light, or remote notification system.

Key Features

• Hazardous Location Certified: Rated Class 1, Division 1, Groups B, C, D for use in explosive atmospheres containing flammable gases or vapors.
• Low Flow Activation: Activates at just 1.5 gallons per minute (3.8 L/min), ensuring immediate alarm notification.
• High Electrical Rating: DPDT contacts rated at 5 A @ 125/250 V AC, suitable for direct control of alarms, relays, or other electrical devices.
• Standard Connections: 1/2" FIPS (Female Iron Pipe Standard) inlet and outlet for easy integration into existing piping systems.
• UL Listed: Certified by Underwriters Laboratories for safety and reliability.
• Durable Construction: Designed for long-term reliability in industrial environments.

Applications

The 5726850 flow switch is ideal for use in:

• Emergency eyewash and safety shower alarm systems.
• Industrial safety monitoring and alert systems.
• Hazardous location installations (Class 1, Division 1 areas).
• Process flow detection for water-based systems.

Installation Notes

Install the switch in the water supply line upstream of the emergency fixture. Ensure proper electrical connections are made in accordance with local codes and hazardous location requirements. The switch should be mounted in a vertical or horizontal position as specified in the installation manual.
