Product Description
ETC MC-31U Magnetic Contact Sensor, 902MHz
Overview
The MC-31 is a wireless contact sensor that monitors the status of an interior window or door. The sensor provides a reliable and simple method to detect occupancy at entry points when combined with an occupancy sensor for hospitality applications that require control to power the room or setback temperature control devices. The sensor can be configured to monitor closed-to-open, and/or open-to-closed transitions, or just the current state of the device. A coin cell battery provides 10 years of operation based on an average of 10 actuations per day
The sensor incorporates features that assist the installer in positioning the device to ensure reliable wireless communications. It also includes diagnostic and configuration features to ensure consistent performance. Configurable settings can be adjusted without special tools
When linked with an Echoflex controller, Range Confirmation technology indicates radio signal strength via LED with a simple button-press and hold sequence.
An optional battery level status message makes it convenient to monitor battery power when the device LEDs are not clearly visible.
These built-in features assist the installer in locating the sensor for optimal wireless performance and be confident of its operation.
