Overview

Safe Signal Waterflow Detector Flow Switches

These Safe Signal Waterflow Detectors, also known as Flow Switches, Water Flow Switches, or Sprinkler Flow Switches, are devices used in fire protection pipe systems to monitor and detect the flow of water. These detectors are installed in pipe systems so water will flow past it, activating the switch to signal to a control panel or alarm system that the fire sprinkler system may be activating. In some cases, false alarms happen, and this product features a timer dial that allows for a set delayed reaction to ensure that water is steadily flowing through the switch.

Along with signaling for water-flow, these detectors verify that water is flowing when it is supposed to, and if the switch doesn’t activate when a known fire event is taking place, it indicates a potential issue in the system or a closed valve. These flow switches are critical in fire protection systems, and many building codes and regulations require their installation.

These Safe Signal detectors consist of a rugged, NEMA 4-rated enclosure that is more damage resistant than other designs. Featuring a corrosion resistant lightweight cover with tamper-resistant cover screws, they have a sealed retard mechanism immune to dust and other contaminants. They are designed for indoor and outdoor use and can be installed vertically or horizontally. They have an operating temperature range of 32-150F and are UL Listed and FM Approved for installation in Steel Schedule 7-40 piping (2-4 in.) or Steel Schedule 10-40 pipe (5-8 in.). They have a triggering threshold (flow rate) of 4-10 Gallons Per Minute (GPM).
