Description

The Stopper 2 STI-1150 consists of a clear, tamperproof, tough polycarbonate shield and frame, but the line includes models with the option of a piezo horn, spacer, Form “C” dry relay contact, and gaskets. This protective cover has been helping to stop false fire alarms around the world for more than 35 years, without restricting legitimate alarms. All models offer excellent protection against physical damage and several against severe environments both inside and out. It is ideal for schools, colleges, hospitals, nursing homes, stores, hotels, and public buildings of almost every kind where there is a threat of false alarms.

The cover accommodates most manual pull stations. When the Stopper II with horn is lifted to gain access to the protected alarm, a piercing self-contained 95 or 105 dB warning horn sounds. Immediate attention is drawn to the area and a prankster will either run or be caught. The cover is connected to the frame by a cable. When the cover is lifted, it drops off of the frame and a horn will sound (models with horn) until the cover is snapped back onto the frame or for the life of the battery.
