The **FTS-02-R/Q** typically refers to a specialized series of **Flame Detectors** or **Thermal Sensors** often utilized in fire suppression systems or industrial automation. These devices are engineered to identify specific wavelengths of light (Infrared/Ultraviolet) or rapid temperature changes to trigger safety protocols. --- ### 1. Key Electronic Components The internal architecture of these sensors generally consists of the following functional blocks: | Component Type | Function | Description | | :--- | :--- | :--- | | **Sensing Element** | Signal Acquisition | Uses a Photodiode or Thermopile to detect IR/UV radiation or thermal energy. | | **Signal Amplifier** | Gain Control | Amplifies the micro-volt signals from the sensor to a level processable by the logic board. | | **Microcontroller (MCU)** | Logic Processing | Analyzes the input signal against pre-set algorithms to prevent false alarms (e.g., distinguishing sunlight from fire). | | **Output Relay/Transistor** | Switching | Provides the physical interface (dry contact or open collector) to the control panel. | | **Status LEDs** | Visual Feedback | Typically includes a Red LED (Alarm) and a Green/Yellow LED (Power/Fault). | --- ### 2. Technical Specifications While specific datasheets vary by manufacturer, the "R/Q" designation usually points to specific output or reset configurations: * **Operating Voltage:** Typically 12V DC or 24V DC. * **Current Consumption:** Low standby current (approx. 10-30mA), higher during alarm state. * **Response Time:** Usually < 5 seconds for flame detection. * **Output Type:** * **R:** Often denotes a **Relay** output (Form A or C). * **Q:** Often denotes a **Quick-connect** or specific high-speed switching variant. --- ### 3. Connection Pinout (General Example) Electronic parts like the FTS-02 usually follow a standardized 4-wire or 6-wire terminal configuration: ```yaml Terminal 1: [V+] Positive Power Supply Terminal 2: [V-] Common/Ground Terminal 3: [ALARM] Relay Contact (Normally Open) Terminal 4: [ALARM] Relay Contact (Common) Terminal 5: [FAULT] Fault Monitor (Optional) ``` --- ### 4. Detection Logic The electronics are designed to filter out "Optical Noise." This is achieved through: 1. **Flicker Frequency Analysis:** Recognizing the 1-20 Hz flickering pattern of a real flame. 2. **Spectral Filtering:** Only allowing specific wavelengths (e.g., 4.3 microns for CO2 emissions in fires) to reach the internal photodetector. ---
