Wireless Open/Closed Sensor

The wireless open/closed sensor provides information on the status of doors, windows, cabinets, etc. Know if a building or specific area is being accessed when it should not be, or if a door or window has been left open.
Monnit WIT Wireless Sensor Specifications
  • 900, 868 and 433MHz operating frequencies
  • 250 - 300 ft. non-line-of-sight device range*
  • Replaceable 3.0V battery
  • At 1 hour heartbeat setting, coin
    cell battery will last ~ 1-2 Years. **
  • Includes Magnet and Mounting Hardware.
     
  • Sense immediate door access.
