## Long description

Wireless window opening sensor TECH C-2N in brown is a compact wireless contact sensor designed to detect the opening and closing of windows and send a wireless signal to compatible alarm panels or control units. Its unobtrusive form factor allows discreet installation on window frames and sashes, making it suitable for residential and commercial security setups as well as simple access monitoring and basic home automation tasks where a non-wired sensor is preferred.
Advantages
The sensor provides wireless detection without the need for cabling, reducing installation time and preserving window aesthetics. Its small size and neutral brown color enable discreet mounting on wooden or colored frames. The device is compatible with standard wireless alarm systems that accept contact sensors and offers reliable open/close reporting for security and automation logic.
Suitable for
 Home security: detecting unauthorized or unexpected window openings
 Office or retail security: perimeter monitoring of display or back-office windows
 Access monitoring: simple occupancy or entry tracking via window status
 Home automation: triggering lights, notifications or HVAC adjustments when windows open
 Renovations and retrofits: adding sensing where running wires is impractical
Key specifications
 Function: magnetic contact sensor for window open/close detection
 Mounting: surface mount on window frame and sash for contact alignment
 Color: brown finish suitable for wood or dark frames
 Form factor: compact housing designed for discreet installation
 Communication: wireless transmission compatible with compatible alarm/control systems
 Power: battery-powered for cord-free operation
How to use
Install the sensor body on the fixed frame and the magnet on the moving sash so that they align at the closed position. Follow the manufacturer’s pairing procedure to enroll the device in a compatible control panel or alarm system and ensure the device is within range of the receiver. Test the sensor after installation by opening and closing the window to verify that the control unit receives state changes. Replace batteries according to system indicators or routine maintenance intervals to maintain reliable operation.
Usage recommendations
Install on clean, dry surfaces using the recommended adhesive pads or screws; avoid mounting where repeated impacts or severe weather exposure could dislodge the units. Place the sensor within the wireless range of the control panel and verify line-of-sight or signal path if interference is suspected. Periodically test and check battery status to ensure continuous monitoring.
