The lack of flashing from the strobe while the horn is functioning correctly could indicate a potential wiring issue or a problem with the strobe itself. Here are a few troubleshooting steps you can take:
Check Wiring Connections: Ensure that the wiring connections between the strobe and the fire alarm control panel are secure and correctly terminated. Loose or faulty connections can disrupt the signaling.
Verify Power Supply: Confirm that the power supply to the strobe is adequate. Insufficient power can cause the strobe to malfunction. Check the voltage levels and ensure they match the specifications provided by the manufacturer.
Inspect Strobe Settings: The EST GCF-HDVMH comes with selectable high output settings. Ensure that the strobe is configured correctly according to the desired output level. Refer to the product manual for instructions on adjusting the settings.
Test with Alternative Power Source: Temporarily connect the strobe to a different power source to determine if the issue persists. This can help identify whether the problem lies with the power source or the strobe unit itself.
If these troubleshooting steps do not resolve the issue, it may be necessary to contact a qualified technician for further inspection and potential replacement of the strobe unit.
