35+ Years of Helping Stop False Fire Alarms

September 6, 2017 - STI announces their Stopper II® pull station protective cover, which mounts directly to the wall over an existing pull station, has helped stop false fire alarms for over 35 years.

When the cover is lifted, a self-contained alarm sounds, drawing immediate attention to the area. The cover helps deter pranksters from triggering false fire alarms, reducing unnecessary business interruptions or evacuations. When a real alarm is needed, the cover does not restrict legitimate fire alarms from being activated.

“Since we recommended the installation of STI Stopper II covers over our manual pull stations, false fire alarms have ceased to be a problem,” states Robert Lindstrom of Will Rogers Airport Fire Department.

The Stopper II is UL/cUL Listed, FM, and ADA Compliant. Three year guarantee against breakage of polycarbonate in normal use (one year on electro mechanical and electronic components).
