accentra alarm panic button reset?

Hi,
The house we let/rent has an accentra alarm panal and panic box around 9 years old. It does not list the model or make - only accenta. I wiped to top of the panic box and the red insert inside clicked down, setting off the panic alarm. I typed in my code into the key pad but it now reads...attack.
The alarm can not be set in this attack mode. How do you reset the panic button?
