What to do if the Menvier Security Control Panel display shows 'UNSET AC OFF' and beeps?
- MMichelle BenjaminAug 20, 2025
This indicates that the mains power to the Menvier Security Control Panel is off, or the internal fuse has blown. The system will operate from the internal battery for about 8 hours. To address this, enter your passcode to silence the beeps. If the mains power to the building is on, contact your alarm company.
