Wireless Entry Indicator CEE GB212 — wireless door/window entry sensor, model GB212

CEE GB212 is a wireless entry indicator designed to detect and report the open or closed status of doors and windows. The GB212 model uses a wireless connection to integrate with compatible control systems, enabling remote monitoring of access points and signaling entry events to alarms or automation controllers. The device is compact and intended for use in residential and commercial installations where unobtrusive status indication and reliable contact detection are required.

Advantages

The GB212 provides contact state detection without the need for wired connections, simplifying installation and reducing visible wiring. Its wireless operation allows flexible placement on doors or windows and easy integration with alarm panels and smart home controllers that support compatible wireless protocols. The sensor’s compact form factor and low profile make it suitable for environments where discreet monitoring is preferable.

Suitable for

• Monitoring doors and windows in homes
• Access point detection in small offices or shops
• Integration with alarm systems to trigger alerts on open/close events
• Use in automation scenarios to change lighting or HVAC when doors/windows are opened

Key specifications

• Function: wireless open/close contact sensor for doors and windows
• Mounting: surface-mounted on frame and sash (typical installation)
• Power: battery powered for wireless operation (replaceable battery)
• Communication: wireless link to compatible control systems for status reporting
• Physical: compact, low-profile enclosure intended for unobtrusive installation
• Compatibility: designed to work with compatible CEE or third-party control/automation systems supporting the same wireless protocol

How to use

Position the sensor and its magnetic element so they align when the door or window is closed and separate when it opens. Fix both parts to the frame and moving part using the recommended screws or adhesive according to the mounting surface. Insert or verify the battery and follow the control system’s enrollment procedure to pair the sensor with the alarm panel or automation controller. Test the sensor after installation to confirm that open and closed states are reported correctly to the control system.

Usage recommendations

For reliable operation, mount the sensor on clean, dry surfaces and ensure the two parts maintain the specified gap when closed. Replace the battery according to the control system’s low-battery indication, and periodically test the device as part of routine system maintenance. When integrating with automation or alarm systems, consult the system manual for pairing instructions and any protocol-specific placement guidelines.
