The **GE6-R** is a specific model of an infra-red (IR) flame detector, often utilized in industrial safety and fire protection systems. Below is a breakdown of its electronic components and technical specifications. --- ### 1. Core Electronic Components The GE6-R operates by detecting specific light wavelengths emitted by hydrocarbon fires. Its internal circuitry is designed for high-speed processing and false-alarm rejection. | Component | Description | | :--- | :--- | | **Infrared (IR) Sensor** | A high-sensitivity pyroelectric sensor tuned to the 4.35-micron range (CO2 emission line). | | **Optical Filter** | A narrow-bandpass filter that shields the sensor from sunlight and artificial lighting. | | **Signal Processor** | An integrated circuit (IC) that analyzes the frequency and flickering of the IR light to distinguish fire from non-fire sources. | | **Relay Outputs** | Mechanical or solid-state switches that trigger alarms or fire suppression systems. | | **Status LEDs** | Light Emitting Diodes (usually Red and Green) to indicate power, fault, or fire detection status. | --- ### 2. Technical Specifications The following table outlines the electronic and environmental parameters for the GE6-R unit: | Parameter | Specification | | :--- | :--- | | **Operating Voltage** | Typically 24V DC (range: 18V to 32V DC) | | **Current Consumption** | Standby: ~20mA / Alarm: ~50mA | | **Spectral Sensitivity** | 4.2 to 4.7 µm (IR range) | | **Output Contacts** | NO/NC (Normally Open/Normally Closed) Dry Contacts | | **Response Time** | Typically < 5 seconds (standard fire) | | **Operating Temp** | -40°C to +75°C | --- ### 3. Connection and Wiring Diagram The GE6-R usually features a terminal block inside its housing. The standard wiring configuration is as follows: 1. **V+ / V-**: Power supply input (24V DC). 2. **Fire Relay**: Connected to the Fire Alarm Control Panel (FACP). 3. **Fault Relay**: Normally energized; it drops out if power is lost or a hardware failure occurs. 4. **Earth/Ground**: Shielded wire connection to prevent EMI (Electromagnetic Interference). ### 4. Key Electronic Features * **Solar Blindness:** The electronic filtering ensures that the sensor does not react to direct sunlight or welding arcs. * **Self-Diagnosis:** The circuitry performs periodic checks of the sensor sensitivity and internal electronics. * **Sensitivity Adjustment:** Some versions include dip-switches or a potentiometer to adjust the detection range (distance) and delay time. ---
