This unique and patented device has been helping stop false fire alarms around the world for more than 20 years, without restricting legitimate alarms.

Stopper II consists of a clear, tamperproof, super tough polycarbonate shield and frame that fits over manual pull stations. The cover is connected to the frame by a cable. When the cover is lifted, it hangs off of the frame until the cover is snapped back onto the frame. Additional models are available with a built-in warning horn that sounds when cover is lifted to gain access to the pull station (see STI-1100).


  • Cover is UV-stabilized.
  • Unlimited lifetime guarantee against breakage to the polycarbonate cover and frame, in normal use.
  • Proven effective for almost two decades.
  • STI-1200 is for flush mount pull stations (Surface - see STI-1230).
  • UL Listed to U.S. and Canadian safety standards (for standard and custom labeling).
  • Polycarbonate rated -40║F to 120║F (-40║C to 49║C).
  • MEA 49-00-E.
  • Fits virtually all manual pull stations (see Technical Data Sheet for dimensions)
