290 Series Door Monitor

The 290 series door monitor from GRI provides access control and perimeter security by monitoring access points leading to or from a controlled area and prevents doors from being accidentally left open or deliberately propped open. The 290 series door monitors are stand-alone alarm systems that can be mounted either locally or remotely to monitor access doors using a simple closed loop magnetic reed switch. It is an ideal solution for single door exits at the end of long hallways or isolated doorways in low-traffic areas.
