Activity Sensor


The EN1240 activity sensor is designed specifically for residential and senior living environments where a notification of daily activity is necessary. The EN1240 leverages the latest motion detector technology, including white light and pet immunity, to ensure performance accuracy. Selectable fixed sleep intervals of two, four, or six hours are used to minimize wireless traffic in large installations, while confirming daily resident activity. Check-in messages are sent every 30 minutes to provide effective notification of recent resident activity even when the device is in the fixed sleep cycle.
