Door Alert

Door Alert is a simple, effective alarm system designed to prevent doors from being left open for extended periods. When a door is left open beyond a set time, the unit activates an audible alarm — prompting immediate action to close the door and restore control. It’s commonly used in environments where open doors can lead to unwanted risks, such as smoke spread, temperature loss, or disruption to controlled areas.
