Introduction
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. 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. Set in a standard calibration to detect a flames at a distance of 25 meters, which flame created by 2Kg ethanol in a Container of Base 33cmX33cm, Height 5cm

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.
WARNIING:
Not to install flame detector near the below subjects:
1. Halogen lamp, Electric discharge lamp, ultraviolet ray lamp.
2. Welding spark, Electric spark
3. Heavy current magnetic field, thunder discharge.
4. Direct sunlight.
5.Ultra violet radiation subjects
The UV flame detector can not detect the following:
1. The flame behind the glass or transparent resin.
2. Lighted cigarette.
3. Burning charcoal and coal cakes.
4. Burning material without flame.
