Alarm Contacts

Alarm Contacts include magnetic contacts, reed switches, door/window sensors, panic and hold-up buttons, and plunger switches designed for commercial intrusion detection. These durable, tamper-resistant devices integrate with alarm panels and access control systems to reduce false alarms, speed response times, and protect assets. Available in wired and wireless options, our selection supports flexible installation, low maintenance, and reliable perimeter and point-of-entry monitoring for offices, retail, warehouses, and multi-site facilities.
