Burglar alarms often use closed loop door and window contacts to provide the best level of security. Closed loop design for commercial and home alarm systems is considered superior for many reasons, including the fact that any attempt to cut a system wire before entering will activate the alarm. Security Store USA enhances this ability with a full line of closed loop sensors available in various gap sizes, mounting methods, and colors.
