First, ensure the panel is powered and in normal operation mode. Then, verify that all wiring connections are secure and properly terminated. Use a multimeter to check for continuity between the zone terminals and the corresponding devices. If there’s no continuity, inspect the wiring for any breaks or shorts. Additionally, check for any fault indicators on the panel and consult the user manual for further guidance. If the issue persists, consider contacting a certified technician for advanced troubleshooting and repair.
