1. **Check Power Supply:** Ensure that the PVX-RM is receiving the correct power supply voltage (24 VDC) and current. Verify that the input voltage and current match the specifications mentioned in the manual (0.033A DC Standby - 0.044A DC Active).
2. **Inspect Wiring Connections:** Review the wiring connections between the PVX-SC supervisory card and the PVX-RM microphone. Make sure the connections are secure and follow the terminal designations provided in the manual.
3. **LED Indicators:** Check the LED indicators on the PVX-RM. The Fault LED (Yellow) should illuminate if there are any issues detected. If the LED is not lit, it could indicate a power supply problem or a fault in the wiring.
4. **Microphone Activation:** Test the microphone by keying it during an alarm condition. Ensure that the microphone is properly keyed to interrupt the alarm signal and broadcast live voice messages. Verify that the In-Use LED (Red) lights up when the microphone is active.
5. **Mic Gain Adjustment:** If there are audio output issues, adjust the Mic Gain using VR1 on the PVX-RM. Turn the xxxx clockwise to increase the microphone gain, which might improve the audio output.
6. **Fault Conditions:** If the Fault LED remains lit or there are persistent issues, refer to the troubleshooting section in the manual for further guidance. It may involve checking for faults in the wiring, circuitry, or power supply.
7. **Technical Support:** If troubleshooting steps do not resolve the issue, contact technical assistance at the provided number (866-956-1211) for further troubleshooting and support.
By following these steps and referring to the provided manual for detailed instructions, users can effectively troubleshoot and address any issues with the PVX-RM microphone in the voice evacuation system.
