Cooper envier 9448+?

The key pad may have gor wet accidentally when my partner was stripping off paper above it with sponge.
The keypad went dead but the alarm sounder in the main box went off for approx 20 mins.
After this time the tamper loop light was illuminated then the keypad started to work, she reset it and there hasn't been a problem since
This was about 7 hrs ago.
Do I need to be concerned about anything please?
