Fire is a serious risk. However, even if the equipment can be tempting to small people, I don’t recommend telling them taping the control panel shut, or posting signs telling people not to touch the fire alarm.
I suspect those intent on fiddling will ignore the sign. While you definitely don’t want to confuse someone in an emergency situation where they *should* sound the alarm.
Instead have regular fire alarm drills. Give training to your volunteers or employees. Suggest training for anyone else who use your building. You might be able to combine groups and provide training to everyone.
These combined with clear signage, plus the use of appropriate equipment coverings to prevent accidental usage or damage will mean fewer false alarms and give everyone involved more confidence that they know what they are doing if an emergency occurs.
