Waterflow Alarm Switch

  • Flow & Pressure Switches – Vane type waterflow switch for use on wet sprinkler systems
  • Pressure Alarm Switch – Designed to detect a pressure increase or decrease in fire sprinkler systems, primarily used to monitor low air pressure conditions in dry systems
  • Ball Valve with Supervisory Switch – Utilizes a ball valve in combination with a switch assembly
  • Tamper & Alarm Switch – Weather proof and tamper resistant switch for monitoring the open position of post indicator, butterfly and other types of fire sprinkler/control valves
  • OSY Tamper & Alarm Switch – Used to monitor the open position of an OS&Y (outside screw and yoke) type gate valve. Mounts conveniently to most OS&Y valves ranging in size from 2″ (DN50) to 12″ (DN300). Can be used on some valves as small as 1⁄2″. Circulates single sprinkler flow and allows testing of flow switch without external discharge of water – replaces traditional Inspector’s test procedure
