Stopper II® Series Polycarbonate Protective Cover, with Horn, Clear Spacer, Spanish Label

Stopper II® Series Covers

For over 30 years, this unique, patented device has helped prevent false fire alarms worldwide without restricting legitimate alarms. It is ideal for schools, hospitals, daycare centers, shopping malls, stores, hotels, and almost all types of public and private buildings where the threat of false fire alarms exists.

The Stopper II® series consists of a durable, tamper-evident, clear polycarbonate cover and a frame that fits over manually operated lever stations. When lifted to access the alarm, a high-pitched 95 or 105 dB warning siren sounds. This immediately draws attention to the area, and the prankster will either run or be caught.

The Stopper II® series is intended for use in areas where the incidence of false fire alarms from manually operated pull stations is high or has proven to be a serious problem. Any disadvantages of this device are more than outweighed when considering the consequences of false fire alarms, especially if service personnel and equipment respond to a false alarm. Add to this the disruption to facility operations when a false alarm occurs. The Stopper II® can be invaluable. For over 30 years, this unique, patented device has helped prevent false fire alarms worldwide without restricting legitimate alarms. It is ideal for schools, hospitals, daycare centers, shopping malls, stores, hotels, and public and private buildings of almost all types where the threat of false fire alarms exists.
