GENERAL DESCRIPTION
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.
