IR Explosion Proof Flame Detector Fire Alarm System

Product Description

JTGB-UF-C35Ex Point Type IR Flame Detector Summary
JTGB-UF-C35 Ex point type infrared flame detector the flame multispectral signal acquisition method and full-frequency wave analysis technology are adopted to avoid the vulnerable weakness of traditional detectors. The detection environment is monitored by increasing slope signal detection technology (PAM), which improves the stability and sustainability of the detector. It ensures that the detector can quickly identify and detect fire while minimizing false alarm.
The detector is suitable for various types: oil depot, wine depot, aircraft hangar, chemical equipment site, military equipment site, liquefied gas station, power station, etc. High anti-interference ability, not affected by wind and rain, high temperature, high humidity and natural artificial light source, can work well in indoor or outdoor environment (with lens hood)
The detector adopts a six-wire connection mode (two power lines, two fire touch spot lines, and two fault touch spot lines). When alarming, the fire touch spot changes from normally open to normally closed, while when reporting fault, the fault touch spot changes from normally closed to normally open, which can be connected with the fire alarm system of any manufacturer.
Technical Parameter Spectral response:1.1~3.2um. Response time:5~10s . Monitoring angle:≤90°. Working voltage: DC24V. Static operating current: 25mA±3mA. Alarm status current: 35mA±5mA. Sensitivity: I class ~ III class. I class: 0-25m within the scope of the probe must be reported to the fire.
IIclass: 0-17 m within the scope of the probe must be reported to the fire.
III class: 0-12 m within the scope of the probe must be reported to the fire. Protection grade: IP66 Environment temperature: -10 ~ +55ºC Relative humidity: ≤93%RH(45±2ºC) Installation angle: rotation angle: 360°. Elevation angle: 90°. Exd II CT6 Gb;Ex tD A21 IP66 T80ºC. Cable outlet thread: NPT1/2″ nut explosion-proof hose is connected with outlet screw. Product size: Φ60×150mm.
Status Indicator Green: work indicator light, on when normal, internal device failure report green light does not work. Red: alarm indicator, normally off, often on fire. Power outages reset
Output model Fire relay: normally open, close when alarming. Fault relay: normally closed, disconnected in case of fault Touch spot capacity: 3A /220VAC 3A /30VDC Use and Maintenance
Wiring: The wiring is shown in the picture. The red and black wires are connected to the positive and negative electrodes of the DC24V power supply. The yellow and white line is the contact output of the alarm relay, which closes when alarming. The green and blue line is the output of the fault relay, which is fault relay output, normally closed, fault disconnect. If module has terminal resistance, connect blue and green lines, yellow and white lines and terminal resistance, Resistance should be installed as close as possible to the detector. It is not recommended to install resistors near modules.

Red	DC: +24V	Connect the controller to the power supply DC24V
Black	DC: -24V
White	Fire relay touch spot output, dry contact normally open, closed in case of fire	Connect the alarm module signal end
Yellow
Blue	Fault relay touch spot output, dry contact normal closure, fault disconnect.	After connecting the terminal resistance in series, it is connected to the signal end of the alarm module or to the module return route in series.

Installation Requirement Overlooking installation: overlooking Angle < 45°. Installation distance: The protection distance of detectors in oil sites is 3m ~ 5m.
The protective space of chemical sites is 5m ~ 7m.
The protection distance of smelting site is 7m ~ 10m.
The protection spacing of power sites is 2m ~ 10m. Installation height: when the suspended ceiling is installed, the detector is 0.3m way from the roof. Wall mounted installation: the detector ≥2.5 m from the ground. Try to avoid infrared interference sources within the detection Angle. When there is a fire, the flame can't touch the detector. When there is an automatic spray system, its influence on detector should be considered, and protective measures should be taken when necessary. There should be no obstacles blocking the line of sight of the detector in the fire area. If the obstacles cannot be avoided, the number of detectors should be considered to achieve no-dead Angle detection. Detector shell should be ground.
