3. FAQ
| Problem | Solutions |
| The indicator light of the module flashes quickly, and the screen of Fire Alarm Control Panel displays “Add or replace equipment” | While adding or replacing equipment, re-register in the System Debugging menu on the Fire Alarm Control Panel |
| The indicator light of the module flashes quickly, and the screen of Fire Alarm Control Panel displays “LA repeated equipment information” | Find and take off the wrong coding device, rewrite the code with the encoder, and re-register on the Fire Alarm Control Panel after installation |
| The indicator light of the module does not light up, and the screen of Fire Alarm Control Panel displays “Registered device is offline” | Check whether the device is installed in place; if it is installed correctly, check the circuit, measure and ensure that the voltage of the equipment signal line is between 16V DC and 28V DC |
| The indicator light of the module flashes quickly, and the screen of Fire Alarm Control Panel displays “Open Circuit (Short Circuit) Fault” | Terminal 3 and 4 should be connected with 47 KΩ resistor |
