Safe Signal T-Tap Waterflow Detector Residential Flow Switch

This Safe Signal T-Tap Waterflow Detector, also known as a Flow Switch, Water Flow Switch, or Sprinkler Flow Switch, is a device used in residential fire protection pipe systems and branch line signaling to monitor and detect the flow of water. This detector is 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, this detector verifies 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. This Waterflow Detector fit any tee that has a 1 in. NPT branch, including 1 in., 1-1/4 in., 1-1/2 in., and 2 in. NPT threaded ferrous and brass tees; 1 in., 1-1/4 in., 1-1/2 in., and 2 in. copper sweat tees; and Tyco, Spears, NIBBCO brand 1 in. CPVC tees.
