UMAX U-Smart Motion Sensor UB913 — wireless motion detector, model UB913

The UMAX U-Smart Motion Sensor UB913 is a compact wireless motion detector designed for residential and small-office security and smart-home automation. The device monitors movement within its coverage area and sends signals to compatible control panels or hubs to trigger alarms, lighting scenes, or notifications. Its small form factor allows discreet placement on walls or corners while maintaining reliable detection performance for typical indoor environments.

Advantages

The UB913 provides reliable motion detection with low visual impact, suitable for integration into existing security systems and smart-home setups. Wireless connectivity simplifies installation without extensive wiring, and the sensor’s compact design enables flexible placement. The device is intended to work with compatible control units to deliver timely alerts and automate responses such as switching lights or activating sirens.

Suitable for

• Home intrusion detection in rooms, hallways and entryways
• Small-office security monitoring
• Smart-home automation to trigger lights or scenes based on presence
• Supplementing existing alarm systems with additional motion coverage

Key specifications

• Device type: wireless passive infrared (PIR) motion detector
• Intended use: indoor motion monitoring
• Mounting: wall or corner placement for optimal coverage
• Power: battery-powered for cable-free installation
• Connectivity: wireless link to compatible control panels or smart-home hubs
• Coverage: designed for typical room-sized areas (wide-angle PIR coverage)

How to use

Install the UMAX U-Smart Motion Sensor UB913 at an elevation and position that provides a clear view of the monitored area, typically on a wall or in a corner 1.8–2.4 meters above the floor for best detection of walking persons. Follow the integration procedure for your control panel or smart hub to pair the sensor and configure detection zones, sensitivity and alarm actions. Test the sensor after installation to verify coverage and adjust angle or position if necessary. Replace batteries according to the control unit’s battery status indications.

Usage recommendations

For consistent performance, avoid pointing the sensor directly at windows, heating vents or areas with rapid temperature changes. Use the sensor as part of a coordinated security layout together with door contacts and cameras to minimize false alarms and ensure comprehensive coverage.
