3.2 Adjustment Frame
The adjustment frame can rotate by 60°around the axe, as shown in Fig. 3.
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 classifications (please refer to Section 6
Operation), and then install it according to Fig. 4.

Step 1: Install the adjustment frame.
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.
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.
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≥1.0mm

, 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.

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
outlet shall be inserted with an blanking element with O-ring.
If Z1 and Z2 does not connect with the loop, they must be connected with D1 and D2
polarity-insensitively.

5 Testing
Warning: Power up only after all detectors are installed.
1 The detector must be tested after installation and regular maintenance.
2 Tests:
(1) Connect the detector to loop and 24VDC, it should be able to be registered by
the control panel, and the red LED should flash periodically. 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 The address and classifications can be programmed using a handheld programmer.
Please refer to the manual for the programmer.
The range of address is 1~242.
For setting classifications, number 1 represents class 1, number 2 for class 2 and
number 3 for class 3.
2 If the detector connects with the loop, it needs to be programmed with an address
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

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.
