I am looking after my sons place and he has a Yale house alarm. I have used it successfully many times but today on entry the normal warning beeps came on, I pressed the unlock button followed by the 4 digit code and to my horrer the screen said error code and the warning beeps continued. 
At this stage should I have a) pressed the unlock button followed by the 4 digit code, or simply re submitted the 4 digit code?. I was in panic mode but after a few minutes of the alarm shreiking I was able to cancel it. I accept I could have made the initial 4 digit error but What should I have done then? I really dont know how I stopped it, but it was not sounding long enough to have timed out. Thanks
