Product Overview
The JTY-GD-HA821-485 photoelectric smoke and fire detection alarm (hereinafter referred to as the alarm) can detect the smoke generated during a fire. The alarm adopts photoelectric smoke sensing devices and excellent production technology, with stable operation, beautiful appearance, simple installation, and no need for debugging. It can be widely used in shopping malls, hotels, shops, warehouses, computer rooms, residential areas and other places for fire safety detection. The alarm is equipped with a built-in buzzer, which can emit a strong sound after sounding an alarm. The alarm adopts standard 485 signal output, Modbus protocol, and supports secondary development.

Wiring Instructions
The power input can be 10~30V. When wiring the 485 signal line, be careful not to connect wires A and B in reverse, and ensure that the addresses of multiple devices on the bus do not conflict.
2. Connect the power and signal lines to the installation base, and install the detector on the base
Red "and" black "represent non-polar input of DC power supply;
Blue and yellow "are 485A (3 legs) and 485B (4 legs)
Installation Instructions
1. Use screws to fix the installation base plate to the ceiling.
2. Align the positioning protrusion at the bottom of the detector with the positioning groove on the installation base
Rotate clockwise to install the detector.
Parameter Settings
1. Select the correct COM port (check the COM port in "My Computer - Properties - Device Manager - Ports").
2. Connect only one device separately and power it on. Click on the software's test baud rate, and the software will test the current device's baud rate and address. The default baud rate is 4800bit/s and the default address is 0x01.
3. Modify the address and baud rate according to usage needs, and also query the current functional status of the device.
4. If the test is unsuccessful, please recheck the equipment wiring and 485 driver installation
