An Intruder Alarm System is a security system that detects unauthorised entry using sensors such as door contacts, motion detectors and glass-break sensors, signalling a control panel that raises local and remote alarms. In data centers it protects perimeters, plantrooms and secure areas outside normal access hours, integrating with monitoring stations and access control for coordinated response.
