Components that detect, process, communicate, and announce alarm events
A typical intrusion system connects detection devices to a control panel that monitors protected zones, evaluates system activity, activates local notification, and communicates alarm events to authorized users or monitoring services.
Perimeter & Opening Protection
Contacts and perimeter sensors monitor doors, windows, gates, fences, overhead doors, and exterior approaches for opening, movement, or attempted entry.
- Door and window contacts
- Overhead-door and gate contacts
- Photoelectric beam sensors
- Fence and perimeter detection
- Shock and vibration sensing

- Specialized environmental sensors
Control, Communication & Notification
Control panels supervise system zones, manage arming and disarming, activate notification devices, store event history, and communicate alarm or trouble conditions.
- Alarm control panels and keypads
- Zone and output expansion
- Cellular and network communication
- Sirens, horns, strobes, and speakers
- Power, battery backup, and accessories
