Explosion Proof Dual IR Flame Detector relay output
Fire alarm relay output Fault relay output IR2 EXdIICT6 Product function and composition A705/IR2 can be applied to the need to monitor the implementation of the fire place, quickly found that the fire may cause the burning flame, issued in a timely manner Fire alarm. A705/IR2 is converted to electrical signal by two infrared pyroelectric sensors which work in different bands. Signal input industrial computing chip for comparison, operation and processing, with the detecter&anysafe II Ir dedicated intelligent control software, you can Send out a fire alarm in time. A705/IR2 uses the aluminum die-casting flameproof shell, has good protective properties and explosion-proof, corrosion resistance, aging resistance, can work for a long time In the indoor, outdoor and all kinds of special industrial places.

UV flame detector fire alarm
Flame Detector with Relay Output 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. Loop Design and Wiring The system designer must make sure that the total current drawn by the devices on the loop does not exceed the current capability of the panel supply, and that the last device on the circuit is operated within its rated voltage. When calculating the voltage available to the last device, it is necessary to consider the voltage drop due to the resistance of the wire. The thicker the wire, the smaller the voltage drops. Wire resistance tables can be obtained from electrical handbooks. SETTING FOR WORKING MODE 1. Alarm Relay Output NO/NC setting: 2. Alarm detect timer setting: Quick detect flame Stable setting( Default setting) Detect flame in smoking area Some special place such as sunshine interfere place 3. Alarm Output mode setting Alarm status latch off (Unlock) Alarm status latch on (Lock) 470 ohm output, connected with conventional fire alarm panel Relay Contacts Output (Default setting) 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. SPECIFICATIONS Operating Voltage Range: 12 to 28 VDC Volts Standby Current: ≤10 mA @ 24 VDC Alarm Current ≤40 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 Protection rating: IP 21 Operating Humidity Range: 10% to 93% Relative Humidity, Non-condensing Operating Temperature Range: -20°C to 55°C Height: 45 mm installed in Base Diameter: 103 mm Weight: 153g
