Universal Stopper® has helped stop false alarms for over 40 years without restricting legitimate alarms. Polycarbonate protective cover helps prevent false alarms, saves possible municipal fees, disruption, evacuations, unnecessary gatherings breaking COVID-19 social distancing standards, and a loss of productivity. When the cover is lifted, a self-contained 95/105 dB warning horn sounds. Immediate attention is drawn to the area and the prankster will either run or be caught before a false alarm is pulled.

Clear indoor/outdoor cover does not restrict legitimate use of fire alarm. Surface mounted cover. UL/cUL Listed, ADA Compliant.
