Tamper Switches

Sprinkler systems are a firefighter’s best friend. Capable of putting the all-important first-water-on-fire far faster than even the most diligent municipal fire services, sprinklers help to extinguish and contain fire, as well as create a safer environment for firefighters to work in.

Supervisory or tamper switches are an integral component of a sprinkler system sending a signal to the fire alarm panel when a control valve is closed thus shutting down the sprinkler system. Alerting the fire alarm system of an unauthorized or accidental valve closure can prevent disaster or even loss of life. Crafted with quality in mind by Potter, tamper-proof switches can help ensure your system is engaged when you need it most.

Compliant with NFPA 13 and built to withstand a wide range of temperatures, these supervisory switches are available to fit a variety of sprinkler control valve options. Monitor your system with confidence by using only the highest quality products available here at Herbert Williams.
