Presence detector P42LR, 230 V, 2-channel, master, 32 – 37 m, 360°, SnapFit, for flush-mounted installation, white 353-701221

Intelligent lighting and HVAC control with presence sensor

This advanced presence sensor, designed for flush-mounting, is the ideal solution for both installers and end-users looking for comfort and energy savings. The device offers a wide range of configuration and control options for lighting and HVAC systems (heating, ventilation, and air conditioning). Thanks to its dual-channel design, it allows independent control of lighting and air conditioning circuits, increasing installation flexibility.

Functionality and configuration options

The P42LR sensor stands out with its large detection range – up to 37 meters – making it perfect for large office spaces, production halls, or public areas. SnapFit mounting simplifies and speeds up installation in various types of suspended ceilings. Remote control via the Niko Detector Tool app (available on iOS and Android) and two-way Bluetooth communication allow for precise adjustment of settings to individual needs. The application also enables real-time monitoring of the device status and access to the event log.

• Wide range: Up to 37 meters provides coverage even in large spaces.
• Dual-channel: Independent control of lighting and HVAC systems.
• SnapFit mounting: Quick and stable mounting in various types of suspended ceilings.
• Mobile app: Intuitive configuration and remote control using the Niko Detector Tool.
• Bluetooth communication: Two-way communication for fast modification of settings.
• Master/slave system: Possibility to expand the system to 10 secondary sensors to increase the range.
• Adjustable PIR sensitivity: Four sensitivity levels allow optimal adaptation to environmental conditions.
• Delay-off function: Setting the time from when a person leaves to when the light turns off (from 15 seconds to 2 hours or ∞ mode).
• PIN settings lock: Protection against unauthorized configuration changes.

Construction and technical parameters

The sensor is made of high-quality thermoplastic, ensuring its durability and resistance to damage. It has a protection rating of IP20, which means protection against touching foreign objects with a diameter greater than 12.5 mm. It is equipped with solid potential-free N.O. relays, which allow controlling loads up to 2300 W for incandescent and halogen lamps and 350 W for LED lamps. Thanks to the possibility of connecting additional modules, the functionality of the device can be extended with additional control options.

The technologies used ensure reliable operation in a wide range of ambient temperatures (-25°C to +40°C). The built-in anti-theft mechanism further increases the security of the installation. The device complies with safety standards and has a CE certificate.
