Use a multimeter to verify you have 12V between H+ and H-. | | Strobe doesn't flash | Trigger wire disconnected or strobe unit faulty. | Confirm ST- is correctly wired to the panel's strobe output. | | "Tamper" fault on the panel | Sounder cover is open, tamper loop is open, or incorrect EOL resistor fitted. | Ensure both the main and backplate covers are securely closed. Check the loop resistance. A forum post notes "Galaxy uses 1k for everything". | | Unit produces random "chirps" | Unit's self-test has detected an internal fault, like a failing battery. | Check the FAULT terminal output. Test the battery health and voltage. If the battery is old (2-3+ years), replace it. | | Siren won't stop sounding | Engineer hold-off (+12V) not applied; the tamper circuit is shorted. | On some panels, the sounder will only reset after the tamper circuit has been closed. If the issue persists, power down, disconnect the backup battery, and re-check all wiring. | Note: Always disconnect mains power before opening the unit
