WENTRONIC Goobay 2‑zone adjustable/swivel motion sensor, black, model 79597

The WENTRONIC Goobay 2‑zone adjustable/swivel motion sensor in black (model 79597) is a passive infrared detector designed for indoor monitoring of two separate detection areas. The unit provides directional adjustment and a swivel mechanism to aim each sensing zone independently, enabling targeted coverage for corridors, stairways, entryways or rooms where selective motion detection is required. It operates using PIR technology to detect moving heat sources and can be integrated with lighting circuits or alarm inputs for automated control and energy savings.

Advantages

This 2‑zone PIR sensor offers adjustable detection angles and a swivel function so installers can set coverage precisely without repositioning the entire housing. Its two-zone layout helps avoid unwanted triggers by allowing the user to focus monitoring on specific areas while excluding others. The black finish is intended to blend with dark interiors and fixtures. The sensor is suitable for straightforward wiring into indoor lighting and alarm systems and is built for typical household and light-commercial environments.

Suitable for

• Automated indoor lighting control in corridors, stairwells and entry halls
• Selective motion detection for rooms with zoned coverage requirements
• Integration with alarm systems to trigger alerts on detected movement
• Energy-saving control where lights are switched only when movement is present

When it may not be suitable

The sensor is optimized for indoor use and passive infrared detection; it is not designed for outdoor installation or exposure to direct weather. Locations requiring wide-angle or full-room coverage without zoning may be better served by a ceiling-mounted panoramic detector. It may also be unsuitable where detection must function through glass or with constant thermal sources that can mask movement.

Key specifications

• Detection principle: passive infrared (PIR)
• Number of detection zones: 2 independently adjustable zones
• Mounting orientation: adjustable swivel for directional aiming
• Finish: black
• Intended location: indoor use
• Typical applications: lighting control, alarm input, energy-saving automation

How to use

Mount the sensor at the recommended indoor height and position so the two sensing zones cover the intended areas. Use the swivel and adjustment features to aim each zone precisely, avoiding pointing directly at heat sources or vents. Connect the sensor to the lighting circuit or alarm input following the wiring diagram provided by the installer or product manual, and perform walk tests to confirm reliable detection and to adjust sensitivity or angle as needed. Regularly check alignment after any interior changes that could affect detection paths.

What to consider before purchase

• Confirm that the installation location is indoors and sheltered from weather.
• Determine whether two adjustable zones meet coverage needs versus a single wide-angle sensor.
• Consider compatibility with the lighting or alarm system voltage and wiring method.
• Assess mounting position to avoid direct exposure to heating vents, windows or constant heat sources.

Usage recommendations

For reliable operation, place the sensor so moving subjects cross the detection zones rather than approach directly, and perform a test walk through at typical speeds and clothing to fine-tune the swivel and angle settings for optimal response while minimizing false triggers.
