Cover to extend life of electronic devices 
Data
STI’s Widebody Keypad Protector helps prevent vandalism and theft of larger keypads, access controls and similar devices. It also increases the life and reliability of protected devices by shielding them from dirt, dust and grime as well as severe environments.
Two models are offered, one without a lock (STI-6550/STI-6550S) and one with (STI-6560/6560S). Each comes in either clear or smoked. With a gasket, it can help keep water out in wet locations and hose-down areas.
Stopper® II with Horn Flush Mount 
Data
This unique and patented device has been helping stop false fire alarms around the world for more than 25 years, without restricting legitimate alarms. Ideal for schools, hospitals, nursing homes, stores, hotels and public buildings of almost every kind.
Stopper II consists of a clear, tamperproof, super tough polycarbonate shield and frame that fits over manual pull stations. When lifted to gain access to the actual alarm, it sounds a piercing 95 dB or 105 dB warning horn. 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 hangs off of the frame and the horn will sound until the cover is snapped back onto the frame (or for the life of the battery).
