Possible Causes

Corrupted control pack memory, Loose keypad or sensor connections, Electrical interference or power surge

Safety first: Turn off power at the breaker before unplugging any control components.

Power cycle: Leave power off for at least 60 seconds, then restore. This can clear transient software errors.
Check keypad cable: Inspect the topside control panel cable where it enters the control pack. Ensure it is fully seated and not damaged.
Inspect sensors: Reseat all sensor connectors on the control board.
Surge protection: If SE recurs after storms or power events, consider adding a surge protector and have the control pack evaluated by a technician.
