June 7, 2010 - Safety Technology International, Inc. started with a challenge from a suburban Detroit school administrator more than three decades ago. He made it to Jack Taylor, founder of a firm specializing in security systems since 1970. "Jack, we need your help stopping false fire alarms. They create havoc-which we don't want." Taylor and his associates went to work on the challenge, and created the world famous Stopper^® II, a cover to help prevent false fire alarms. This resulted in a new company and the Stopper^® Line of over 300 products.

To further establish their mark in the industry, STI took steps to UL List many of their protective covers. UL Listing is extremely important when dealing with life safety devices such as pull stations, smoke detectors or strobe/horn appliances.

The STI Smoke Detector Wire Guards (STI-9600 series) are UL Listed. Protective guards inhibit smoke entrance to the detector, but STI's UL Listed guards help assure they are listed to operating capacity.

STI's Horn/Strobe Damage Stoppers^® (STI-1210A-E series) offer protection against vandalism and damage to your appliance. Wire cages and polycarbonate covers will cause light loss. Light loss factors need to be considered when engineering a strobe layout and characteristics of the protective device have to be taken into account when constructing a system. Customarily the degree of light loss caused by a protective cover is unknown, but with STI's UL Listed covers, the de-rating factor is identified and listed to UL standards.

In problem areas with false fire alarms or vandalism to pull stations (schools, public buildings, etc.), a protective cover will reduce or eliminate false alarms. According to national and local codes, these fire alarm pull stations must be UL Listed. To avoid negating the alarm's UL Listing, confirm the protective cover is also UL Listed (such as STI's STI-1100 or STI-6600 pull station covers).
