Hi Isabella, thanks for reaching out. First, check the power supply to ensure the Wheelock ELSPKWC-N is receiving the correct voltage. If the power is good, inspect the wiring for any loose connections or damage. Sometimes, a faulty connection can cause issues with the strobe. If everything looks fine, it might be worth trying a reset if applicable. If the problem persists, let me know, and we can explore further troubleshooting steps.
