Flow Switch | Fire Protection Flow Switch
Flow Switch is a monitoring device for fire-protection systems. It detects water flow in the line and sends a signal to an alarm or monitoring system. When water begins flowing through a sprinkler system, the switch provides an electrical alert and communicates with the fire alarm, automation, or monitoring infrastructure.
The body is available for different pipe sizes from Ø50 (2 in) to Ø200 (8 in). It is rated for 300 psi / 21 bar and has a flow sensitivity range of 15–37.5 L/min (4–10 gpm). Contact ratings are 10(3) 125/250 V AC and 6 A at 24/30 V DC. The maximum retard time is 90 seconds, and the switch is compatible with Schedule 10–40 pipe. It is a dependable choice for projects that require flow monitoring in fire-protection lines.
