Another Fire Protection Upgrade Complete
Today, the Fairfield Fire Protection team replaced two deficient OS&Y tamper switches, keeping this fire sprinkler system code-compliant and ready when it matters most.
What’s an OS&Y Tamper Switch — and Why Does It Matter?
OS&Y (Outside Screw & Yoke) tamper switches monitor the main control valves on a sprinkler system. If a valve is moved from the fully open position, the switch sends a supervisory signal to the fire alarm panel—alerting you before your building is left unprotected.
When a tamper switch is damaged, misaligned, or not working properly, a valve could be shut without anyone knowing. That’s why routine inspections and quick repairs like this are critical to life safety.
Need Your Sprinkler System Inspected or Repaired?
Routine inspections and repairs catch deficiencies like this before an inspector — or a fire — does.
