Abstract
A dead-bolt receptacle unit and monitoring system which allows an operator to quickly and efficiently determine a status of a dead-bolt, i.e. whether the dead-bolt is bolted or unbolted. A dead-bolt receiving unit is provided into which a dead-bolt cylinder is inserted. A dead-bolt detecting unit is formed in a dead-bolt receiving unit, and the dead-bolt detecting unit detects a presence of the dead-bolt cylinder in the dead-bolt receiving unit. The dead-bolt detecting unit further outputs a dead-bolt detecting signal which is based on the detected presence of the dead-bolt cylinder and the dead-bolt receiving slot. A central indicator unit receives the dead-bolt detecting signals output by each dead-bolt detecting unit, and provides an indication of the status of each dead-bolt, i.e. whether each dead-bolt is bolted or unbolted. Such a system allows an operator to quickly and easily determine the status of each dead-bolt in a home.
