Product Description
24v Uv Flame Detector Relay Output Fire Alarm Sensor
The device is an Ultraviolet-only flame detector designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. It detects in the ultraviolet(UV) spectral range for optimized speed of response.
It is fast and capable to detecting the ultraviolet (UV) rays emitted by a burning substance and is used in high hazard applications such as petrochemical plants, munitions factories and other areas where flammable or explosive liquids or solids are handled or stored.

High performance imported UV light sensitive tube
The flame sensor adopts an ultraviolet photosensitive tube, with qualities of highly sensitive, reliable, dust-resistant, corrosion proof and moisture-resistant, therefore is not sensitive in sunlight, dust, oil, tolerance of fume, and humidity.
Function characteristic
* The detector is built with MCU and intelligent algorithm, which can realize fast alarm and reduce false alarm rate
* Relay output mode (normally open/normally closed), can directly control other equipment
INSTALLATION：
NOTE: All wiring must conform to applicable local codes, ordinances, and regulations.Mounting Indoor Wall or Ceiling Products
1. Attach mounting base to ceiling or wall.2. Connect field wiring to terminals:
Terminal 1: Relay Output –COM (ZONE+)
Terminal 2: Relay Output – NO/NC (ZONE-)
Terminal 3:DC Power – Terminal 4: DC Power +
3. To attach product to mounting base.
4. Secure product by tightening the two mounting screws in the front of the product housing.
5. The detector can be connected with Security alarm panel as Figure3. Relay output signal can be changed from Normal Close (NC) to Normal Open (NO) by Jump JP1 on the PCB board.
6. The detector can be connected with conventional alarm panel as Figure 4. One 4.7K ohm resistor should be connected as End of Line (EOL) resistor at the last detector.
7. After the installation, power on the detector, use lighter or candle to test the detector within 3 meters.
