High-Standard Fire Alarm Flame Detector With 12-28 VDC Operating Range
Introduction
The DC24V Ultraviolet Flame Detector is a specialized sensor designed to quickly detect the presence of flames in high-risk environments. It utilizes ultraviolet (UV) light sensing technology to identify the unique UV radiation signature emitted by burning substances, providing fast and reliable fire detection capabilities.

Standby Current: ≤10 mA @ 24 VDC
Alarm Current ≤30 mA @ 24 VDC
Spectrum: 180~290nm
Detection Angle: 120 degree
Detection Sensitivity: Grade I, 25m@flame (Container 33cmX33cm,Height 5cm with 2Kg ethanol )
Relay Contact Load: 1A@DC24V
Normal Status: LED blinking in 5 seconds interval
Alarm Status: LED lit steady
Operating Humidity Range: 10% to 93% Relative Humidity, Non-condensing
Operating Temperature Range: -20°C to 55°C
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.
