What to do if there are false alarms from the detector on my Ravel Control Panel?
If your Ravel Control Panel is showing false alarms from the detector, it might be due to a faulty detector or an issue with the EOL resistor. Ensure that the AC supply is within the range of 185 - 245v. If the issue persists, consider changing the faulty detector.
Why is my Ravel Control Panel showing a hooter fault indication?
A hooter fault indication on your Ravel Control Panel can arise from connection problems in the hooter or a loop fault. Here's what to check: * If no hooter is connected to the output, verify if an EOL resistor is connected. * Use a meter to check the loop wiring for shorts or opens. * For non-polarized hooters, ensure each hooter’s positive loop is connected to the cathode of a 1N 4007 diode, and the hooter’s negative loop is connected to the anode of the 1N 4007.
How to troubleshoot a Ravel Control Panel with no indication?
If there is no indication on your Ravel Control Panel, the cause may be no power to the panel. Check both the AC power and the standby power.
What to do if the Detector OPEN is not detected by the Ravel Control Panel?
If the Ravel Control Panel isn't detecting a Detector OPEN, it could be because the total zone loop current exceeds the rated value. Check the number of detectors connected in the loop, ensuring that the total detector current does not exceed 3mA.
