Help when the product does not work
Choose the symptom and check the model scope before following the steps. This is troubleshooting, not a list of confirmed product defects.
PowerMaster shows NOT READY
Applies to: PowerMaster-10 G2. PG2 accessories only when fitted to this panel; not PowerG+ or IQ Panel.
- Read the display and review open zones/faults as described in the user guide. Record the zone, room and full message.
- For an open door or window message, close it fully. Look to see whether the magnet and sensor are still in place.
- Check the display again. Battery, tamper or communication faults require the named sensor manual. Do not replace the panel battery because of a sensor fault.
- When the panel is ready, use normal arming. Do not bypass an unknown zone or force arm to remove the warning.
Check the result: The panel shows READY with no unresolved fault and normal control works.
Stop and get help: If the zone remains open or the fault concerns communication/tamper, contact support with the zone and sensor model.
