4.3Installation Notes
4.3.1Suitable installation location
When installed on the roof, it should be placed in the middle of the roof. If it is installed on the
inclined or human roof, the alarm should be kept at a certain distance from the roof. When the
slope is less than 30°, the distance is 0.2m, more than 30°. The distance is from 0.3m to 0.5m.
4.3.2 Location and environment to avoid installation
1. Places where smoke is normally trapped
2. Locations with large dust, water mist, steam, oil mist pollution and corrosive gases
3. Locations with relative humidity greater than 95%
4. Locations with ventilation speeds greater than 5 m/s
5. Close to fluorescent fixtures
4.3.3 installation method
Two mounting holes of 5 mm in diameter were placed at a distance of 60 mm from the ceiling,
and the detector base was fixed to the ceiling with a plug and a screw.

5.2parameter settings
1. Select the correct COM port ("My Computer - Properties - Device Manager - Port"
to view the COM port). The following figure lists the drive names of several different
485 converters.
2. Connect only one device and power on separately. Click the test baud rate of the
software. The software will test the baud rate and address of the current device. The
default baud rate is 4800 bit/s and the default address is 0x01.
3. Modify the address and baud rate according to the needs of use, and query the
current functional status of the device.
4. If the test is not successful, please re-check the equipment wiring and 485 driver
installation

6.2 Data frame format definition
Adopt Modbus-RTU communication protocol, the format is as follows:
Initial structure ≥ 4 bytes of time
Address code = 1 byte
Function code = 1 byte
Data area = N bytes
Error check = 16-bit CRC code
End structure ≥ 4 bytes of time
Address code: is the address of the transmitter, which is unique in the communication network (factory default 0x01).
Function code: The instruction function of the command sent by the host. This transmitter only uses function code 0x03
(read register data).
Data area: The data area is the specific communication data. Note that the 16-bit data high byte is in front!
CRC code: Two-byte check code.

7. Common problems and solutions
The device cannot be connected to the PLC or computer, possible reasons:
1) The computer has multiple COM ports, and the selected port is incorrect.
2) The device address is incorrect, or there is a device with a duplicate address (all the factory
defaults to 1).
3) Baud rate, check mode, data bit, stop bit error.
4) The host polling interval and the waiting response time are too short and need to be set to more
than 200ms.
5) The 485 bus is disconnected, or the A and B lines are reversed.
6) If the number of devices is too large or the wiring is too long, the power should be supplied
nearby, add 485 enhancer, and increase the resistance of 120Ω terminal.
7) The USB to 485 driver is not installed or damaged.
8) Equipment damage.
