The lack of audible alarms and LED indicator illumination on your Hochiki DH-100-P could indicate several potential issues. Firstly, ensure that the power supply to the device is intact and that there are no loose connections. Check if the device is receiving power and if the wiring is properly connected.
If power supply and wiring are confirmed to be in order, the next step is to check the device itself for any internal faults. This might involve opening up the device and inspecting for any visible damage or loose components. However, please exercise caution and ensure that you’re following proper safety protocols when dealing with electrical equipment.
If no obvious faults are found upon visual inspection, it’s recommended to consult the device’s manual for specific troubleshooting steps or contact Hochiki technical support for further assistance. Remember, working with fire alarm equipment requires expertise and caution, so if you’re unsure, it’s best to seek professional help.
