Our world is full of threats. The buildings and systems we interact with everyday are designed to limit our exposure to the risk of fire, bodily harm and other such threats. We tend to take for granted many of the safety features afforded us by these systems, but nevertheless they influence our daily lives. The days of locking all the doors and handing out keys are gone. Access control systems with anti-tailgate technology, door prop alarms and automatic door operators compliment electrified door hardware products. These products can provide greater protection, more conveniences and help us avoid the unimaginable.
