Fig. 3 3.3 Operation Principle The detector uses two pyroelectric infrared sensors to detect the change of light signal of flame and background light signal at two bands of infrared spectrum through two signal processing channels. Its microprocessor analyzes the signal through the flame channel and background channel to judge if there is flame. 4 Installation and Connection 4.1 Installation Before installation, check first if the enclosure is in good condition with all necessary markings. Then set the detector address and sensitivity level (please refer to Section 6 Operation), and then install it according to Fig. 4.

Fix the adjustment frame securely on the wall using 4 M6 expansion bolts. Step 2: Install the base. Remove the protective cover (Fig. 5) from the base leaving the screws and washer with the base, and install the base onto the adjustment frame using a M5 screw. Aligning Element Protective Cover Fig. 5 Step 3: Cable connection. Pleaser refer to “Connection” section. Step 4: Install the cover. Remove the protective washer, insert the ribbon cable to XT3 of the base circuit, and then install the enclosure onto the base with reference to the aligning element with the U-shaped slot and secure the four screws using an Allen key. Note: The base and enclosure shall be securely installed. There shall not be any scratches or cracks on the detection window. The enclosure shall be earthed. Protective washer U-shaped slot Fig. 6 Finally, adjust the frame to make sure the detection window is facing the protected area, and fix the screws after adjustment. Note: The detector shall be installed in compliance with relative installation codes and make sure the enclosure is in good condition. Please always contact your installer in case of any off-normal condition. Never conduct maintenance or repair with the power on. 4.2 Connection (1) It is recommended to use multi-core copper cable with core cross section≥ Page 4 D-9107RExd Digital Flame Proof Dual IR Flame Detector Installation and Operation Manual 1.0mm 2, and external diameter 8mm～10mm. (2) The cable shall meet field requirements on resistance to explosion, heat, corrosion and fire. (3) The cable layout for hazardous explosive area must comply with corresponding codes. The connecting cable can be copper-core screened cable or explosion-proof hose with suitable junction thread matching with the detector taper thread of the cable nut (Fig. 7). (4) The cable must enter the detector through the junction nut, and there must be an O-ring, a seal and a washer, as shown in Fig. 7. Fig. 7 (5) Connect the screen cover of the cable with the protective earth inside the detector. (6) Terminals on the base are shown in Fig. 8. FT1 FT2 AL1 AL2 Fig. 8 Z1, Z2: Communication loop input from fire alarm control panel. Polarity insensitive. D1, D2: 24VDC power input. Polarity insensitive. AL1, AL2: Fire alarm contact output. Normally open contact. Closed in fire alarm. FT1, FT2: Fault contact output. Normally closed contact. Open in fault. The loop cable and the power shall enter the detector through a cable nut, and the signal cable through another cable nut (Fig. 9). If no signal cable is needed, the cable inlet shall be inserted with an end cap with O-ring. If Z1 and Z2 does not connect with the loop, they must be connected with D1 and D2 polarity-insensitively.

After the detector is powered up for 20 minutes, igniting an infrared light source at 1.5m distance in front of it, it shall report a fire alarm to the control panel within 30s and light the fire LED, and it should be reset from the control panel to standby state. (2) Connect the detector to 24VDC only, the red LED should flash periodically in standby state. After the detector is powered up for 20 minutes, igniting an infrared light source at 1.5m distance in front of it, it shall give fire signal within 30s and light the fire LED. 3 After testing, reset the detector from control panel if it connects to the loop. If it’s not connected to loop, disconnect 24VDC power and re-power it up. Notify the proper authorities the system is back in operation. 4 If a detector fails in testing, clean and test it again. If it still fails, return it for repair. 6 Operation 1 2 The address and sensitivity level can be programmed using a handheld programmer. Please refer to the manual for the programmer. The range of address is 1~242. For setting sensitivity level, number 1 represents sensitivity level I, number 2 for level II and number 3 for level III. If the detector connects with the loop, it needs to be programmed with an address Page 6 D-9107RExd Digital Flame Proof Dual IR Flame Detector Installation and Operation Manual to be identified by the control panel. If it doesn’t connect with the loop, no address setup is required. But terminal Z1 and Z2 must be connected with D1 and D2 in an polarity-insensitive way. 7 Application 1 Fig. 10 shows the connection of the detector with GST fire alarm control panel.

If there is no problem, replace the detector. Page 7 D-9107RExd Digital Flame Proof Dual IR Flame Detector Installation and Operation Manual Registration failure Other problems 9 Maintenance 1 2 3 The detection window should be cleaned at least every three months. Before cleaning, notify relative departments that the system is undergoing maintenance and will be out of service. Disable the zone or system in maintenance to avoid unwanted alarms. After cleaning, install the detector back and test again. 10 Caution (1) The detector should be handled with care during maintenance to avoid damage. (2) Installation and maintenance should strictly comply with relative codes for explosive and hazardous areas. (3) Never open the cover for maintenance in field. (4) The enclosure must be earthed. (5) False alarms may occur if there is arc welding operation within 5 meters to the detector. (6) The following places are not suitable for the detector: Where flameless fires are to be expected. Where intensive smoke spreads before flames. Where the "view" of the detector is easy to be obscured. Where the sun can directly shine the detection window. Where the detector may encounter frequent vibration. 11 Accessories 1 installation and operation manual 4 M6×60 expansion bolts 1 M5×10 screws 1 adjustment frame 1 Allen Key Page 8 Gulf Security Technology Co., Ltd.
