Bosch RFMS-ZBMS-3 Wireless Sensor 3 pack

The ZigBee® wireless multi-sensor is a surface-mount wireless selectable function detector. By default, the detector is a Door Window Detector for monitoring door or window open or closed position. The detector can also be configured as a Water Detector or Tilt Detector. The Low Temperature Alarm Function, which detects when the temperature is less than 40°F (5°C), is an option available when the detector is configured as a Water Detector. The detector also monitors temperature, and includes tamper detection. The ZigBee® compatible radio allows connection to a security or home automation system.
