Door/window wireless reed switch Paradox DCTXP-2 – magnetic contact sensor, wireless connection

Paradox DCTXP-2 is a wireless reed (magnetic) contact sensor designed to monitor door and window openings and transmit status changes wirelessly to compatible Paradox alarm control panels. The sensor consists of a magnet and a reed switch module that detect separation or alignment of the magnet and send a wireless signal when the contact state changes. It is intended for perimeter security and entry-point monitoring in residential and commercial installations where a wireless connection simplifies installation and wiring.

Advantages

The Paradox DCTXP-2 offers a compact form factor and wireless connectivity that reduces installation time and eliminates the need for wiring between the contact and the control panel. Its magnetic sensing principle provides reliable detection of openings while maintaining low power consumption for long battery life. Compatibility with Paradox wireless systems enables straightforward integration into existing alarm setups and centralized status reporting.

Suitable for

• Monitoring doors and windows in homes and apartments
• Perimeter entry monitoring for retail and office premises
• Temporary or retrofit installations where running wires is impractical
• Integration with compatible Paradox alarm systems for intrusion detection

Key specifications

• Type: Wireless reed (magnetic) contact sensor
• Function: Detects open/closed state of doors and windows
• Wireless communication: For transmission to compatible Paradox control panels
• Power: Battery-powered for wireless operation
• Installation: Surface-mounted magnet and sensor components
• Operating principle: Magnetic field detection via reed switch

How to use

Mount the magnet on the moving part of the door or window and the reed switch module on the fixed frame so that the two components align when the opening is closed. Follow the manufacturer’s instructions for pairing the sensor with a compatible Paradox wireless receiver or control panel, typically using the system’s enrollment or learning mode. Ensure correct spacing and orientation for reliable detection and replace batteries according to the system’s low-battery indicators or scheduled maintenance intervals.

Usage recommendations

Place the sensor and magnet on clean, dry surfaces and avoid mounting where heavy vibration or strong external magnetic fields could cause false alarms. Verify wireless signal strength at the intended installation location and, if necessary, reposition the wireless receiver or use compatible signal repeaters to ensure consistent communication with the control panel.
