Satel GRAPHITE Wired Passive Infrared PIR Motion Detector

The Satel GRAPHITE is a professional wired passive infrared (PIR) motion detector engineered for high-performance indoor security applications. Utilizing advanced Fresnel optics and a dual pyroelement, this sensor provides reliable and precise motion detection across a wide coverage area exceeding 100 square meters. Its digital motion detection algorithm, combined with automatic temperature compensation, ensures consistent operation in various environmental conditions, minimizing false alarms while maintaining high sensitivity.

Advantages

The primary benefit of the Satel GRAPHITE is its exceptional coverage efficiency, which allows for effective protection of large spaces with fewer units, thereby reducing overall installation and hardware costs. The device features a user-friendly design that supports remote LED control, allowing installers to toggle the indicator light without dismantling the housing. Furthermore, the inclusion of an alarm memory function simplifies system diagnostics by identifying which specific detector triggered an event. The robust construction includes tamper protection and continuous monitoring of the signal path and power supply, ensuring a high level of security and operational integrity.

Suitable for

• Residential alarm systems
• Commercial office security
• Retail store monitoring
• Indoor warehouse protection

When it may not be suitable

This detector is designed exclusively for indoor use and is not suitable for outdoor environments where exposure to moisture, direct sunlight, or extreme temperature fluctuations could compromise performance. It is also not intended for areas with high levels of steam, dust, or rapidly moving objects that may interfere with infrared detection.

Key specifications

• Detection technology: Passive Infrared (PIR)
• Coverage area: Over 100 square meters
• Optics: Fresnel lens system
• Sensor type: Dual pyroelement
• Digital processing: Digital motion detection algorithm with temperature compensation
• Tamper protection: Integrated tamper switch
• LED indicator: Remotely switchable

How to use

The detector should be mounted on a wall at the recommended height to ensure optimal coverage of the protected area. Once installed, the sensitivity can be adjusted to match the specific dimensions and environmental conditions of the room. The LED indicator can be enabled during the initial setup and testing phase to verify detection zones and subsequently disabled for discreet operation. Wiring should be connected to a compatible alarm control panel, ensuring that the signal path and power supply are correctly configured to utilize the device's monitoring features.

What to consider before purchase

• Ensure the mounting location is free from obstructions that could block the Fresnel lens.
• Verify compatibility with your existing wired alarm control panel.
• Consider the room temperature and potential heat sources that might affect PIR sensitivity.
• Confirm that the installation environment is strictly indoors.

Usage recommendations

For optimal performance, it is recommended to perform a walk-test after installation to verify the detection range and adjust sensitivity settings accordingly. Regularly inspect the device for dust accumulation on the lens to maintain detection accuracy.
