When I press the silence alarm, the sound signal disappears, but not the alarm itself. Pressing reset doesn't change anything; the alarms remain active.

Hello everyone, I’m working with two Kentec Syncro ASM analogue addressable marine fire panels that are networked together. I’ve run into a problem with a stuck fire alarm on one panel and network/battery faults on both panels after a power/battery sequence. Here is the full situation: --- Chronology 1. A detector activated a fire alarm. The detector later returned to normal, but the fire alarm stayed latched on Panel A, while Panel B showed no fire. 2. Pressing RESET on both panels did nothing — the fire event remained stuck on Panel A. 3. To try clearing the alarm, the following steps were taken: Batteries on Panel A were disconnected while AC power was still present. Then AC power was switched off for both panels. AC power was restored. Afterwards, the batteries were reconnected to Panel A. 4. After this sequence: Panel A still shows the same stuck fire alarm even though the detector is normal. Panel B now shows Battery Missing, even though its batteries are physically connected. Both panels show General Fault and Power Fault. RESET still has no effect. No configuration changes were made. No engineer-level tools (Loop Explorer) were used. This is purely the result of the power/battery sequence. --- What I need help with 1. What is the correct and safe recovery procedure to: clear a stuck fire event on one Syncro ASM panel, and re-synchronize the network between two panels after a mixed battery/AC power interruption? 2. Is the “Battery Missing” on Panel B likely caused by an actual power issue, or can it be triggered by a network desync between two ASM panels? 3. Are there steps that can be performed without engineer-level access, using only: front panel controls, power cycling, battery reconnection — to restore both panels to normal? 4. If anyone has experience with marine Syncro ASM units, please let me know if this behaviour is typical when one panel loses battery power while the other remains active. --- I can provide photos I can post photos of: both LCD screens, all LEDs, network card LEDs, battery compartments, exact fault messages. Just let me know what would be most helpful. --- Thanks in advance for any advice. This system is currently not clearing the fire alarm and both panels are showing faults, so any guidance on a proper recovery sequence would be greatly appreciated.
