Wireless input siren with motion sensor GreenBlue GB212 — 52 white tunes, 230V, supports up to 8 sensors

The GreenBlue GB212 is a wireless input siren with integrated motion detection, designed for audible alerts in homes and small commercial premises. Powered by a 230V connection, it offers 52 selectable white tunes and can be connected to up to eight external sensors for expanded monitoring. The device combines motion sensing and external input capability to provide timely alarm signals when movement or sensor triggers are detected.

Advantages

The unit provides a reliable 230V power supply and a choice of 52 distinct white tones for clear audible signaling. Integration of a motion sensor and support for multiple external sensors enables flexible coverage of entry points and interior spaces. Its wireless input capability simplifies wiring requirements for connected detectors, while configurable melodies allow prioritization of different alarm sources. The siren produces a clear sound output suitable for rapid detection and response.

Suitable for

• Home security: entrance halls, living rooms, garages
• Small offices and retail locations
• Supplementing existing alarm panels with wireless sensor inputs
• Areas where visual or immediate audible alerts are required

Key specifications

• Power supply: 230V AC
• Integrated motion sensor for local movement detection
• Selectable melodies: 52 white tunes
• Supports connection of up to 8 external sensors
• Wireless input interface for external detector signals
• Clear audible output suitable for indoor alerting

How to use

Install the siren in a central indoor location with access to a 230V outlet and within wireless range of any external sensors. Configure the device by selecting one of the 52 available tunes according to the desired alert profile. Pair external sensors to the wireless input according to the sensor and siren instructions, keeping the number of paired devices within the supported limit. Ensure the built-in motion sensor orientation covers the intended detection area and test alarm responses after installation to verify coverage and audibility.

Usage recommendations

For reliable performance, mount the siren at an elevation that maximizes motion sensor coverage and sound distribution, avoid obstructing the sensor or speaker grills, and periodically test connected sensors and the siren tone selection. Use the configurable melodies to differentiate between sensor types or zones, and ensure external detectors are positioned to reduce false triggers while maintaining necessary coverage.
